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.

Power-follow is a condition where the 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 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

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-3CDEFT-32 with any equipment other than those recommended may damage equipment, create a shock hazard, and create a fire risk!

Description

The CM-3CDEFT-32 3-Phase Coupler/Decoupler is a single-enclosure, floor- standing ordesktop test system designed to couple EFT events to a 3-phase AC Mains. Single & Multiple line coupling for EFT per IEC standards with the Thermo Scientific EMCPRO PLUS Test System. A Coupler/Decoupler is required to apply surge and EFT 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 EFT energy which may couple to the AC Mains of the building [Decoupler]. The CM-3CDEFT-32 is a manual tester, in which the EFT operation is programmed from the front panel via switches. Programming is fast and simple. Operation is semi-automatic when used with EMCPro series test equipment, a Personal Computer, and the CEWare software, where the CEWare software can provide pauses and prompt the operator to change switches .

Installation

Assembly Instructions
The CM-3CDEFT-32 requires two people for unpacking. Check the packaging materials and follow any special unpacking instructions shipped with your unit. The CM-3CDEFT-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-3CDEFT-32 is returned for service. Carefully check all shipping materials for accessories which may be packaged with the CM-3CDEFT-32.
Voltage Selection
The CM-3CDEFT-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-3CDEFT-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 inletassembly 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-3CDEFT-32 can be placed alongside, placed on top or placed under an EMCPro. The CM-3CDEFT-32 has an AC Mains cord which plugs into the rear of the unit, via a standard IEC-320 connector. This provides fan and control power to the CM-3CDEFT-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 cord is provided to connect the CM-3CDEFT-32 to the building AC mains. A matching pin and sleeve connector for connection to the building mains must be provided by the customer, 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-3CDEFT-32 front panel. Five, unassembled safety socket connectors are provided with the CM-3CDEFT-32; additional connectors are available from MultiContact.  The cable to the Equipment Under Test must be built to the customer requirements. Thiswiring 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-3CDEFT-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-3CDEFT-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 EMCPro EFT Output to the CM-3CDEFT-32 Input Thermo Scientific CM-3CDEFT-32 3-Phase Coupler/Decoupler

• The EFT cable connects the CM-3CDEFT-32 EFT inlet to the EMCPro EFT-Output jack.
• The cable is an HN-coax, which screws tight to each connection.
• The maximum programmed EFT voltage should not exceed the 4400V rating of the CM-3CDEFT-32

Direct Current Power to EUT
The CM-3CDEFT-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-3CDEFT-32 is internally protected at 32 or 16 amperes. When used with a singlephase AC, or Direct Current (DC) power source, if the EUT load or cabling requires current limiting protection of less than the CM-3CDEFT-32 rating, it is the responsibility of the user to provide that protection.

Electrical Supply Requirements

The CM-3CDEFT-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-3CDEFT-32. The voltage range may be easily changed with a screwdriver, following the directions of the Installation, Voltage Selection section of this manual. The CM-3CDEFT-32 is rated for EUT/ AC power source of:

CM-3CDEFT-32

• 250/433 Vac, 32 ampere, 3-phase, 5-wire, 50/60 Hz (U.S.)
• DC : 30Adc up to 24Vdc; 25A up to 48V; 8A up to 100V

The EUT, AC power source should be fused or protected for a maximum of 100 amperes. The over current protection of the CM-3CDEFT-32 includes detection of imbalanced phasecurrents. When using the CM-3CDEFT-32 with a one-phase load, a two phase load, or a load with extreme imbalance between phase currents, the over current protection will trip at a load current of 85% of the CM-3CDEFT-32 rating. 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.

2 Power-follow is a condition where the pulsed 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.

Use of the CM-3CDEFT-32 with Ground-Fault Interrupters (GFI)

• Problems may result when using the CM-3CDEFT-32 on AC mains protected by Ground- Fault Interrupters (GFIs).
• The problem is due to a clamp circuit, protecting the building Mains from excessive voltage during surge, and from the coupling network which connects the generator to the AC mains during the event, 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 CM- 3CDEFT-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.

Physical Environment

The CM-3CDEFT-32 systems are intended for operation in a laboratory environment, protected from excess dust, humidity, and temperature.

• No condensing humidity or standing water on the floor or work surfaces.
• No significant dust or other contamination.

Operating limits

• Temperature: 15 – 40° C
• Humidity: 10 – 85%, non-condensing
• Altitude: 10,000 feet max.

Storage limits

• Temperature: 0 – 60° C
• Humidity: 10 – 90%, non-condensing
• Altitude: 10,000 feet max

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. For EFT testing the EFT generator and CM-3CDEFT-32 should be mounted on the floor, on the ground reference plane. For other testing, the EFT generator and CM-3CDEFT-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 cartcombination 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 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.

Special Considerations for EFT Testing

EFT testing involves the use of very high frequency pulses. For this reason the testing standards specify the use of a ground reference plane in the area where EFT testing is performed. In addition, the standards specify the minimum and maximum spacings among the various equipment present in the test area. This device complies with the requirements of the EMC Directive, 89/336/EEC, as stated in the declaration of Conformity. However, EFT test pulses are by nature an interference test and can therefore create a possible source of disturbance to other electronic equipment that is not intended for test. This device should be used in an environment free of other equipment that could be affected by these emissions, or in a shielded room.The floor of the test area is to be covered with copper or aluminum with a minimum thickness of 0.01 inch, which must be bonded to building Protective Earth (PE) ground. In addition, the cabinet of the EFT generator and CM-3CDEFT-32 must be directly tied to the ground reference plane. Provision for a mounting bracket is made on the rear and bottom of the CM-3CDEFT-32 and the bracket and screws are provided. See the EMCPRO manual, for further information on EFT testing.

Handling, Transportation, Storage

Save all shipping materials (shipping boxes, foam pieces, bags, and special instructions) for possible future shipments. The CM-3CDEFT-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-3CDEFT-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.

Introduction

A Coupler/Decoupler is required to apply surge and EFT 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 EFT 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 EFT and 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 EFT energy. They must also safely couple the surge or EFT  generator to a high- voltage AC Mains For EFT, the CM-3CDEFT-32 is designed to operate with the EMCPro series. The coupling network required to connect the surge to the AC Mains is built into the CM-3CDEFT-32. Operating the CM-3CDEFT-32 with any equipment other than those recommended may damage equipment, create a shock hazard, and create a fire risk! Thermo Scientific CM-3CDA 3-Phase Coupler/Decoupler The CM-3CDEFT-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: EMCPro to CM-3CDEFT-32 Interconnections, Equipment Under Test Connections and the User Interface (Programming).

EMCPro to CM-3CDEFT-32 Interconnections

• From the front Panel of the EMCPro and CM-3CDEFT-32 an HN-coax connects the
• CM-3CDEFT-32 EFT inlet to the EMCPro EFT Output to CCL jack.
• This cable screws tight to each connection. Maximum programmed voltage should not exceed the rating of the CM-3CDEFT-32 — 4400V).

Equipment Under Test Connections:
Connection to the Equipment Under Test (EUT) is via five safety sockets on the lower right of the CM-3CDEFT-32 front panel. Five, unassembled safety socket connectors are provided with the CM-3CDEFT-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 is not a problem.
• The wiring to the EUT should be rated for the expected fault current of the CM- 3CDEFT-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-3CDEFT-32 is selfresetting. In the event of an Overload, as indicated by the chassismount Overload indicator, switch the EUT power switch off or remove EUT Mains input and wait for Overload to clear.
Programming EFT
To program EFT, first connect the CM-3CDEFT-32 and EFT generator using the coax cable provided with the CM-3CDEFT-32.

Connect EFT Output on the EFT generator to the coax connector of the CM- 3CDEFT-32. Use the cables supplied with the CM-  3CDEFT-32 — do not substitute. The EFTcable should be disconnected from both the CM-3CDEFT-32 and the EFT generator when not performing tests. The CM-3CDEFT-32 supports single- line to 5-line COMMON MODE EFT coupling per IEC 61000-4-4. The CM-3CDEFT-32 is manually programmed by setting the EFT COUPLING MODE switches to the desired coupling mode. The EFT can be coupled from 1 to 5 lines (L1, L2, L3, N, PE) in any combination.

All EFT events are with respect to the ground plane. The polarity of the event is always as set at the EFT generator.
NOTE! EMCPRO Firmware v6.00 and up adds two new output modes for EFT testing to accommodate separate calibrations for using the CM3CDEFT external coupler/decoupler in Normal and Common mode. The previously-labeled “Direct” output mode has been changed to “CCL” (the capacitive coupling clamp), because all three modes use the “Direct” output connector.

Programming EFT

• For CM-3CDEFT-32 EFT operation the EMCPRO must be programmed with
• Output: Coupling set to — CM3CD NORMAL or CM3CD COMMON.
• Depending if performing single line or multiple line testing.
• This sets the EFT output to the EMCPRO front panel coax connector.

For all pre-programmed tests, remember that you are only testing the single coupling mode that you have programmed at the CM-3CDEFT-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-3CDEFT-32 is a manual unit. it is programmed by switches 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 CM-3CDEFT-32 switches, allowing semi-automatic testing.

Maintenance

• Service and Maintenance Issues
  There are no user serviceable parts within the CM-3CDEFT-32. Service is solely by Thermo

• Fisher Scientific trained, authorized technicians.
  The system power connector contains a fuse block, holding two, 5mm, 1.0A 250V timedelay fuses. These may be replaced by removing the mains cordset from the power connector and prying the cover off the fuse holder with a small screw driver.

• Factory Inspection and Refurbishment
  Factory Inspection and Refurbishment is available. Consult factory for terms and conditions.

• Calibration
  Yearly calibration of the CM-3CDEFT-32 is recommended.
