Immunity Testing Guidelines
DO NOT WORK ALONE.
Do not use the equipment in conditions other than reasonable laboratory
conditions. There should be no condensing humidity or water standing on the
floor or work surfaces; there shouldn’t be significant dust or other
contamination.
Ensure that NO ONE is touching the equipment under test (EUT) during the test
or immediately after the test until AC power to the EUT has been turned off.
Ensure that there is a barrier to act as protection in case the equipment
under test explodes. This may happen due to power-follow1 after a failure. The
barrier should be interlocked to prevent surging and to disconnect all AC if
the barrier is removed.
The equipment under test must be surrounded by sufficient insulating material
to withstand twice the surge voltage. Consider distance to the floor or table
and walls if air is the insulating material.
Ensure that the proper supply mains voltages are applied to both Thermo
Scientific equipment and to the equipment under test, and that the AC branch
circuit is capable of supplying the current.
The ground (protective earth), neutral and phase lines of the AC supply to the
equipment under test supply must be connected properly. Do not defeat the
protective earth connection.
The ground (protective earth), neutral and phase lines of the AC supply to the
Thermo Scientific equipment must be connected properly. Do not defeat the
protective earth connection.
When surging a powered EUT, the mains supply to the equipment under test must
be capable of handling the potential AC fault current (e.g. do not use a UPS
to power the EUT).
Use only equipment which is designed to be safe for the test being performed.
Do not test in a potentially explosive atmosphere (e.g. gas fumes).
Never use equipment that is operating in a strange manner, or that shows clear
indication of abuse.
If probes are in use, be sure they are differential probes which have no
ground connection to the surged ground or to the equipment under test.
1 Power-follow is a condition where the Surge event causes a low-impedance path which full mains current may then flow through. One example of this is a gas-tube arrestor, which maintains a high impedance until a surge event switches it to a low-impedance state; the low-impedance state is maintained until the mains voltage drops below a critical threshold. Similar effects can be seen due to electrical arcs or exploded components.

Safety Concerns During Immunity Testing
Immunity testing is hazardous. The equipment under test (EUT) can ignite,
possibly explosively. Noxious, toxic and sometimes fatal fumes can be
generated by the burning equipment. Accumulated gases may ignite explosively
(i.e., flashover). In an environment where Immunity testing takes place, it is
absolutely crucial that these minimum safety precautions be taken:
Immunity testing should be performed only by properly trained test personnel,
who are experienced in conducting such test, or be observed and supervised by
such experienced personnel. No person subject to heart or neurological
conditions should be allowed to conduct surge tests. Persons with pacemakers
should not be allowed in or near the area where testing is conducted.
Never leave a procedure or a test setup unattended. All personnel working in
the area must be shielded with appropriate eye protection, body
protection and electrical protection. They should not be allowed to work in a
direct line of a possible explosion of the equipment under test. The test area
should be a clear and unobstructed environment dedicated to such tests. The
test area should be equipped with ventilating hoods and blowers to remove
gases that may be caused by exploding or burning components. The test area
should have nonflammable walls and floors plus shielding to contain exploding
parts and flames. There must be fire extinguishers certified for use in
electrical and chemical fires readily available at the test site. DO NOT USE
WATER TO EXTINGUISH AN ELECTRICAL FIRE. All flammable materials and debris
must be outside the test area, and the area must be well marked, preferably by
physical barriers, to prevent accidental intervention by nontest personnel
while a test is in progress.
Thermo Scientific CM-3CDSRG-32 3-Phase Coupler/Decoupler
Inappropriate Uses
The unit must be kept within the environmental limits of the operating
requirements. This includes not using the unit in condensing humidity. There
are no User Serviceable parts inside; do not remove covers. Use only adapters
and cables and accessories which have been approved for use with this unit.
Connect only to Thermo Scientific equipment which has been approved for use
with this unit. DO NOT connect to any other test equipment. DO NOT modify
front panel jumpers for multiple line Surge coupling. Read and follow
directions for connecting equipment.
Operating the CM-3CDSRG-32 with any equipment other than those recommended may
damage equipment, create a shock hazard, and create a fire risk!

Description
The CM-3CDSRG-32 3-Phase Coupler/Decoupler is a single-enclosure, floor-
standing or desktop test system designed to couple SURGE events to a 3-phase
AC Mains. Single line coupling for Surge per IEC standards with EMCPRO PLUS
EMC Test System. A Coupler/Decoupler is required to apply surge to the AC
Mains of the Equipment Under Test. The Coupler/Decoupler connects the output
of a surge generator to the EUT AC Mains [Coupler] and minimize surge or surge
energy which may couple to the AC Mains of the building [Decoupler]. The CM-
3CDSRG-32 is a manual tester, in which the SURGE operation is programmed from
the front panel via programming jumpers. Programming is fast and simple.
Operation is semiautomatic when used with the EMCPro series test equipment, a
Personal Computer, and the CEWare software, where the CEWare software can
provide pauses and prompt the operator to move jumpers for changing coupling
modes.

Installation
Assembly Instructions
The CM-3CDSRG-32 requires two people for unpacking. Check the packaging
materials and follow any special unpacking instructions shipped with your
unit. The CM-3CDSRG-32 comes fully assembled. Save all shipping materials
(shipping boxes, foam pieces, bags, and special instructions) for possible
future shipments. The original shipping materials must be used whenever the
CM-3CDSRG-32 is returned for service.
Voltage Selection
The CM-3CDSRG-32 must be set for the mains voltage at your site. This is
usually done before shipment, but must be checked before installation and use.
On the rear of the, CM-3CDSRG-32 check that the voltage select block is set to
the proper mains voltage. If not correct, remove line cord, pry the voltage
select block from the inlet assembly using a small screw driver; rotate the
block to the proper voltage, as shown to the right, and fully insert in
holder.

Cabling and Interconnections
The CM-3CDSRG-32 can be placed alongside a Surge generator, placed on top of a
Surge generator, or placed under a Surge generator.
The CM-3CDSRG-32 has an AC Mains line cord which plugs into the rear of the unit, via a standard IEC-320 connector. This provides fan and control power to the CM-3CDSRG-32 , and is required for operation. The EUT Power input is a pin and sleeve connector, rated for the current and voltage of the Equipment Under Test. A power cord is provided to connect the CM-3CDSRG-32 to the building AC mains.
A matching pin and sleeve connector (CONN P&S, RECPT, 32A 288/500V, 5W, BLACK, VDE) for connection to the building mains is provided, and installation of this connector may require the services of an electrician.
Connection to the Equipment Under Test — the EUT Load Connection to the Equipment Under Test (EUT) is via five safety sockets on the lower right of the CM-3CDSRG-32 front panel. Five, unassembled safety socket connectors are provided with the CM-3CDSRG-32. Additional connectors are available from MultiContact.
The cable to the Equipment Under Test must be built to the customer requirements. This wiring should be done to meet all applicable, local, safety requirements. In general — but not exclusively — these requirements include the following:
The wiring to the EUT must be rated to withstand the applied mains voltage.
The wiring to the EUT should be rated to withstand twice the applied pulse
voltage, or the wiring should be isolated from the operator and ground so that
insulation breakdown does not create a hazard.
The wiring to the EUT should be rated for the expected fault current of the
CM-3CDSRG-32 (32 amperes) or additional current limiting and protection should
be added.
WHERE CONNECTION TO PE IS REQUIRED FOR SAFETY, A PE CONNECTION MUST BE
PROVIDED.
It is considered good practice for the PE wired connection to be made longer
than any of the other connections; in the event of an accidental
disconnection, the PE terminal is disconnected last.
In addition, some loads may require proper phasing for proper operation. The
user must determine the phase relationships of the building AC mains and check
this relationship at the CM-3CDSRG-32 outputs.
Caution
Construction and assembly of cord, and connection of EUT loads should be done
only by trained personnel with knowledge of electrical safety practices, and
practical knowledge of the electrical and safety requirements of the load.

Connecting the CM-3CDSRG-32 to EMCPro
The CM-3CDSRG-32 accessories kit includes a line synchronization cable PART#
02-701-85100 This cable connects the synch output of the CM-3CDSRG-32 to the
EUT Mains Input connector on the rear of the EMCPro generator.
The synch output carries the AC line voltage. When this connection to an
EMCPro is in place, the tester’s 250V mains limitation applies to the CM-
3CDSRG-32 .
The synch output of the CM-3CDSRG-32 is not intended for general use as a
utility outlet — do not use this outlet for other devices.
Alternatively, this cable can be replaced with a standard IEC cord, connecting
the EMCPro to a single-phase AC Mains. In situations where a neutral is not
available, this can be a simple way to establish line synchronization.
The surge cable Part# 01-301-995-00 which connects the CM-3CDSRG-32 surge
input to the EMCPro H Coil I/O Line Surge Output connections. DO NOT
CONNECT to the EMCPro Surge Output To Telecom Lines connectors — this output
is not rated for AC mains.
These connections are color-coded; match the white connector on the CM-
3CDSRG-32 to the white connector on the surge generator.
The surge cable set should be disconnected from both the CM-3CDSRG-32 and the
surge generator when not performing surge tests.
Direct Current Power to EUT The CM-3CDSRG-32 can accept a single-phase AC, or
Direct Current (DC) power source at the EUT input and provide it to the EUT
output. When connecting a single-phase or DC source it is important to note
the assignment of EUT inlet and outlet connectors.
The CM-3CDSRG-32 is internally protected at 32 amperes. When used with a
single-phase AC, or Direct Current (DC) power source, if the EUT load or
cabling requires current limiting protection of less than the CM-3CDSRG-32
rating, it is the responsibility of the user to provide that protection.
Thermo Scientific CM-3CDSRG-32 3-Phase Coupler/Decoupler
Electrical Supply Requirements
The CM-3CDSRG-32 system power is configured for one of two voltage ranges:
100 – 120 Vac, 50/60 Hz 220 – 240 Vac, 50/60 Hz
The voltage range configured is identified by label on the rear panel of the
CM-3CDSRG32 . The voltage range may be easily changed with a screwdriver,
following the directions of the Installation, Voltage Selection section of
this manual.
The CM-3CDSRG-32 is rated for a EUT, AC power source of:
CM-3CDSRG-32 250/433 Vac, 32 ampere, 3-phase, 5-wire, 50/60 Hz (U.S.) DC:
30Adc up to 24Vdc, 25A 24 to 48V, 8A up to 100V
CM-3CDSRG-32 is restricted to 250/433 VAC when the sync cable is connected to
an EMCPro.
The EUT, AC power source should be fused or protected for a maximum of 100
amperes.
The overcurrent protection of the CM-3CDSRG-32 includes detection of
imbalanced phasecurrents. When using the CM-3CDSRG-32 with a one-phase load, a
two phase load, or a load with extreme imbalance between phase currents, the
overcurrent protection will trip at a load current of 85% of the CM-3CDSRG-32
rating.
If testing with mains synchronization is required — the surge pulses
synchronized with the AC Mains — then a neutral reference connection must be
provided at the EUT inlet connector. If neutral is not available, then a
neutral reference must be created via a delta-towye transformer or load, and
the neutral reference should be externally fused or protected for the rating
of transformer and wiring.
The synch cable between the CM-3CDSRG-32 and surge generator can be replaced
with a standard IEC cordset, connecting the surge generator to a single-phase
AC Mains. In situations where a neutral is not available, this can be a simple
way to establish a line synchronization reference. The user must then verify
by experiment the synchronization relationship between the single phase and
the three phase lines.
Thermo Fisher Scientific CM-3CDSRG-32 3-Phase Coupler/Decoupler

The EUT power source must have adequate capacity for full power-follow2 in the
event that testing causes an equipment failure. Using a supply without
sufficient capacity may result in a failure being masked.
Acceptable power sources include: A dedicated branch circuit The dedicated
output of a motor-generator (MG) set. The output of a properly rated and
installed isolation transformer.
Use of the CM-3CDSRG-32 with Ground-Fault Interrupters (GFI)
Problems may result when using the CM-3CDSRG-32 on AC mains protected by
GroundFault Interrupters (GFIs).
The problem is due to a clamp circuit, protecting the building Mains from
excessive voltage during surge, and from the coupling network mandated by IEC
61000-4-5 which connects the surge generator to the AC mains during the surge
pulse, and creates a short pulse of mains current in PE, tripping the GFI.
There are two solutions to this problem: The first solution is to power the
EUT from a source that does not have a GFI device
installed. This solution may not be practical in some locations due to
building codes or safety regulations.
The second solution is to install an isolation transformer between the AC
mains and CM3CDSRG-32 . The isolation transformer should be rated for the
current of the EUT load.
Note A solid-state regulated line source such as an uninterruptable power
supply (UPS) or a power frequency amplifier will generally not have the
instantaneous capacity or full power-follow required for Surge and PQF
testing, and therefore should not be used as the AC power source for any
equipment being tested.
2 Power-follow is a condition where the Surge event causes a low-impedance
path through which fault level mains current may then flow: possibly hundreds
of amperes or greater. One example of this is a gas-tube arrestor, which
maintains a high impedance until a surge event switches it to a low-impedance
state; the low-impedance state is maintained until the mains voltage drops
below a critical threshold. Similar effects can be seen due to electrical arcs
or exploded components.

Test Area Considerations and Site Preparation
Conduct Immunity testing under sound laboratory conditions. Verify the
following:
· No condensing humidity or standing water on the floor or work surfaces · No
significant dust or other contaminants · Clear and unobstructed vision ·
Adequate ventilation, including ventilating hoods and blowers to remove gases
· Nonflammable walls and floors · Barriers surrounding the EUT to contain
exploding parts and flames · Appropriate fire extinguishers for electrical and
chemical fires. DO NOT USE WATER
TO EXTINGUISH AN ELECTRICAL FIRE. · No flammable materials or debris inside
the test area. The area must be well marked,
preferably by physical barriers · Keep unauthorized personnel out of the area
during testing
Allow at least six inches clearance from the wall or other equipment on both
sides of the instrument for proper air flow. The system must be mounted on a
level surface. EMCPRO and CM-3CDSRG-32 may be placed on a table that can
support the weight of the units. They may also be placed on a sturdy cart.
However, since the unit is heavy, make certain that the instrument and cart
combination is stable, and cannot be easily tipped particularly if the wheels
strike a bump on the floor such as the edge of a rug, a pebble or a small
piece of hardware.
Special Considerations for Immunity Testing
Immunity testing is best done in an area cleared of obstructions. Clearly mark
the boundaries of the area. There is the possibility that the surge may flash
over to circuits or metal objects not directly under test, and that components
in the equipment being tested may explode or ignite under the stress of the
surge test. Whenever possible, enclose the equipment under test within a
fireproof and explosion-proof barrier having insulation capable of
withstanding at least twice the maximum surge voltage. Never allow direct
line-of-site view of components that may explode or ignite. If visual
observation is required, use a robust transparent barrier of suitable
thickness for protection. Immunity testing should only be carried out by fully
trained personnel who are informed of the hazards of such testing, and who
have full control over all of the test equipment in the area.
Thermo Scientific CM-3CDSRG-32 3-Phase Coupler/Decoupler
Handling, Transportation, Storage
Save all shipping materials (shipping boxes, foam pieces, bags, and special
instructions) for possible future shipments.
The CM-3CDSRG-32 requires two people for unpacking. Follow the instructions in
the INSTALLATION section of this manual and any special instructions shipped
with the unit.
Issues related to transportation of CM-3CDSRG-32 models are identical to those
for installation; the weight of the unit requires that two people help in
packing and movement. When packing the unit for transportation the original
shipping materials should be used, or new materials of equivalent strength and
durability.
For long storage intervals, unplug the power cords of the instrument and cover
the instrument to protect from dust and liquid spills.

CM-3CDSRG-32 Basics
A Coupler/Decoupler is required to apply surge to the AC Mains of the
Equipment Under Test. The Coupler/Decoupler connects the output of a surge
generator to the EUT AC Mains [Coupler] and minimize surge energy which may
couple to the AC Mains of the building [Decoupler]. The circuitry to perform
this is very simple. The generator is connected to the EUT output. Filter
inductors and capacitors in each line attenuate surge energy and reduce the
amount of energy escaping into the building AC Mains. The complications in
this circuitry are in the details: constructing filter inductors which can
block the volt-second product of a 6000 volt, 1.2x50uS pulse, yet which have
very low coupling capacitance to avoid passing SURGE energy. They must also
safely couple the surge generator to a high-voltage AC Mains.
Basic De-Coupler Network
For surges, the CM-3CDSRG-32 is designed to operate with a Thermo Scientific
EMCPro series surge generator. The coupling network required to connect the
surge to the AC Mains is built into the EMCPro.
Operating the CM-3CDSRG-32 with any equipment other than those recommended may
damage equipment, create a shock hazard, and create a fire risk!
Thermo Scientific CM-3CDSRG-32 3-Phase Coupler/Decoupler
The CM-3CDSRG-32 is programmed from the front panel, and all connections to the Equipment Under Test (EUT) are made from the front panel. The front panel controls and features are broken into three major groups: the Surge generator to CM-3CDSRG-32 Interconnections, the Equipment Under Test Connections, and the User Interface (Programming).
EMCPro to CM-3CDSRG-32 Interconnections
The Surge cable Part# 01-301-995-00 connects the CM-3CDSRG-32 surge input to
the EMCPro : H Coil / Surge Output connections.
DO NOT CONNECT to the EMCPro Surge Output To Telecom Lines connectors — this
output is not rated for AC mains.
These connections are color-coded; match the white connector on the CM-
3CDSRG-32 to the white connector on the surge generator.
AC line sync surges, you must install line synchronization cable PART#
02-701-851-00 This cable connects the synch output of the CM-3CDSRG-32 to the
EUT Mains Input connector on the rear of the EMCPro generator.

Equipment Under Test Connections
Connection to the Equipment Under Test (EUT) is via five safety sockets on the
lower right of the CM-3CDSRG-32 front panel. Five, unassembled safety socket
connectors are provided. Additional connectors are available from
MultiContact.
The cable to the Equipment Under Test must be built to the customer
requirements. This wiring should be done to meet all applicable, local, safety
requirements. In general — but not exclusively — these requirements include
the following:
The wiring to the EUT must be rated to withstand the applied mains voltage.
The wiring to the EUT should be rated to withstand twice the applied pulse
voltage, or the wiring should be isolated from the operator and ground so that
insulation breakdown is not a problem. The wiring to the EUT should be rated
for the expected fault current of the CM3CDSRG-32 (32 amperes) or additional
current limiting and protection should be added. WHERE CONNECTION TO PE IS
REQUIRED FOR SAFETY, A PE CONNECTION MUST BE PROVIDED.
User Interface (Programming)
Feedback to the operator is provided by three indicators on the front of the
unit:
SYSTEM POWER is lit when the unit is powered — the rear power switch is set to
ON and the system power cord connected. This indicator must be lit for the
unit to operate.
EUT POWER is lit when the EUT power switch on the front panel is set to ON —
the EUT is energized.
OVERLOAD is lit when there is an over temperature or over current fault and
the EUT power switch on the front panel is set to ON. The unit will not
operate while this indicator is lit.
Warning! EUT load may restart automatically!
The thermal protection within the CM-3CDSRG-32 is self-resetting. In the event
of an Overload, as indicated by the chassis-mount Overload indicator, switch
the EUT power switch off or remove EUT Mains input and wait for Overload to
clear.

Programming CM-3CDSRG-32
To program surges, first connect the CM-3CDSRG-32 and Surge generator using
the surge cable set provided with the CM-3CDSRG-32 .
Connect SURGE HI to SURGE HI, and SURGE LO to SURGE LO. Use Surge cable Part#
01-301-995-00 supplied with the CM-3CDSRG-32 — do not substitute. The surge
cable set should be disconnected from both the CM-3CDSRG-32 and the Surge
generator when not performing tests.
The CM-3CDSRG-32 is manually programmed for surge mode by moving the SURGE HI
and SURGE LO jumpers on the front panel. There are two jumpers required for
any surge event; one jumper is placed in the SURGE HI central socket and
bridges to one of the outer sockets; one jumper is placed in the SURGE LO
central socket and bridges to one of the outer sockets.
As an example, to program SURGE HI to L1 and SURGE LO to PE, place the jumpers as shown below.
SURGE HI should be set to one line to be surged; SURGE LO should be set to the other (SURGE HI and SURGE LO should always be set to different lines; if set to the same line the surge generator will be shorted, and no surge voltage will be delivered. This is a safe condition -the surge generator is designed to withstand shorting — but it does not provide a valid test.).

When surging a line, the polarity of SURGE HI with respect to SURGE LO is always as set at the Surge generator – if the Surge generator is set for a positive surge voltage, SURGE HI will be positive with respect to SURGE LO. Other than polarity, SURGE HI and SURGE LO may be interchanged freely.
There is minimal attenuation of surge waveforms through the CM-3CDSRG-32 ; the voltage programmed at the Surge generator should be delivered to the EUT outlets without attenuation.
The CM-3CDSRG-32 supports single-line to single-line surges.
In all there are 20 coupling modes, of which some are redundant. Eliminating the redundant coupling modes leaves 10 different coupling modes. These are:

For surging to the CM-3CDSRG-32 the EMCPRO must be programmed with Output: Coupling . . . DIRECT. This sets the surge output to the safety sockets. To synchronize to the AC Mains, set the Phase Synch field to L1, and turn the EMCPRO EUT switch ON (If synchronization is not required, set the Phase Synch field to RND, and the EMCPRO EUT switch may be ON or OFF). See the EMCPRO manual for more information on programming options.

For performing AC line sync surges, you must install line synchronization
cable PART# 02-701-851-00 This cable connects the synch output of the CM-
3CDSRG-32 to the EUT Mains Input connector on the rear of the EMCPro
generator.
Most of the EMCPRO pre-programmed tests can also be used with the CM-3CDSRG-32
. To use a pre-programmed test the test must offer the option under coupling
of Output: Coupling: DIRECT. See the EMCPRO manual for more information on
pre-programmed tests.
Pre-programmed tests may use line synchronization; set the Phase Synch field
to L1, and turn the EMCPRO EUT switch ON. When testing is performed with mains
synchronization, a neutral reference must be provided at the EUT inlet
connector. If neutral is not available, then:
a neutral reference must be created via a delta-to-wye transformer or load,
and the neutral reference must be externally fused or protected for the rating
of transformer and wiring, or;
The synch cable between the CM-3CDSRG-32 and EMCPRO can be replaced with a
standard IEC cordset, and connected to a single-phase AC Mains. The user must
then verify by experiment the synchronization relationship between the single
phase and the three phase lines.
When using line synchronization, the EMCPRO will always synchronize to the L1
connection of the CM-3CDSRG-32. To synchronize to another phase, add 120° or
240° to the desired value and enter Phase Sync:Angle: L1: field of the surge
generator. The phase synchronization should be checked with an oscilloscope by
programming a low-voltage surge — within the voltage rating of the
oscilloscope probes used — and measuring the phase reference.
For all pre-programmed tests, remember that you are only testing the single
coupling mode that you have programmed at the CM-3CDSRG-32 front panel. In
many cases, for a complete test, you will have to change coupling mode and
continue until all modes have been tested.
The CM-3CDSRG-32 is a manual unit; it is programmed by moving jumpers and on
the front panel. Since the EMCPro is an automatic unit some care must be taken
on interfacing the two units and in programming. The CEWare software provides
pauses and prompt features which can prompt the operator with pre-programmed
messages and instructions for setting the CM3CDSRG-32 jumpers — allowing semi-
automatic testing.
