Attentions and safety guidelines
Before installing the Bulletin 161 drive and putting it into operation, please
read this user manual carefully and take note of all the Attentions and safety
guidelines. Always keep this product manual near the Bulletin 161 drive so
that it is easily accessible.
Definition of the guidelines
ATTENTION
Failure to comply with these precautions may result in death, serious personal
injury or substantial damage to equipment.
General information
Conventions used in this manual
To help differentiate parameter names and selection tags from other text the
following conventions will be used: · parameter names will appear in italic
(example: C22, d07) · selection tags for inputs and outputs will appear in
[brackets] (example: [RS], [CF1])
ATTENTION
· This Bulletin 161 drive generates dangerous electrical voltages and controls
potentially dangerous rotating mechanical parts. Disregarding the guidelines
provided in this manual may result in death, serious personal injury or
substantial damage to equipment.
· The installation, commissioning and maintenance of these drives may only be
carried out by experienced personnel who are thoroughly familiar with the
functioning of the equipment and the entire machine.
· The devices feature dc-bus capacitors that are live even when the mains
supply is switched off. For this reason wait at least 5 minutes after
switching off the mains supply before you open the device and start working on
it. Take care that you do not touch any live parts.
· The drive is intended to be installed with a fix connection to earth. The
protective earth only offers protection for the drive, not against personal
injury. According to EN 50178 it is not recommended to use the Bulletin 161
drives on protective fault current switches as, due to a possible DC component
(rectifier load), the sensitivity of the safety switch will be reduced in the
event of a failure. If unavoidable, only type B RCD’s should be used. As a
precautionary measure, the EN 50178 regulations should be observed. The stop
button on the integrated control panel may not be used for emergency purposes.
The stop button can be activated via parameter b87.
ATTENTION
Earth the Bulletin 161 drive at the connections intended for this.
iii
Bulletin 161
ATTENTION
· To prevent any injuries or damage, do not touch any components located
within the housing either with your hands or with any other objects if
mains voltage is applied or if the DC-bus capacitors are not discharged. Do
not carry out any work on the wiring or check any signals if mains voltage is
applied.
· Exercise particular caution if automatic restart is activated. To prevent
injuries caused by the automatic restarting of the drive following a power
failure, install a switching component at the mains that is deactivated in the
event of a power failure and that may only be switched on again on return of
the power supply (e.g. contactor etc.). Earth the drive at the connections
intended for this.
ATTENTION
· Ensure that the input voltage corresponds to the voltage indicated on the
product nameplate. Environmental influences such as high temperatures and high
relative humidity are to be avoided as well as dust, dirt and corrosive gases.
The mounting location should be well ventilated and not exposed to direct
sunlight. Install the device on a non-flammable, vertical wall that does not
transmit any vibrations. Attention! Do not apply mains voltage to the output
terminals U/T1, V/T2 and W/T3.
· Please contact the motor or machine manufacturers if standard motors with
frequencies >50 Hz are to be used.
· All Bulletin 161 drives are checked for dielectric strength and insulation
resistance. Insulation resistance measurements e.g. as part of a check may
only be taken between the power terminals and earth. Do not carry out any
measurements at the control terminals.
· In normal operation apply the START/STOP commands via the control terminals
or the control panel and not by disconnection and reapplying input power to
the drive or motor contactor. Do not install any capacitors or suppressors to
the drive output terminals.
ATTENTION
· To ensure that your Bulletin 161 drive functions safely and reliably, all
the pertinent safety regulations, e.g. accident prevention regulations,
professional association regulations, EN, VDE regulations etc. must be
observed. As these regulations are implemented differently in different
countries, the user must observe the regulations that apply for his particular
country. Rockwell Automation cannot release the user from complying with the
latest relevant safety regulations.
· The technical data and descriptions in this user manual have been created to
the best of our knowledge and belief. Enhancements to products are being made
continually – Rockwell Automation therefore reserves the right to make
modifications without previous notice.
· In spite of the care taken in producing this manual, Rockwell Automation
cannot be held liable for any errors and damage arising from the use of this
manual.

3. Installation
ATTENTION
· Environmental influences such as high temperatures and high relative
humidity are to be avoided as well as dust, dirt and corrosive gases. The
mounting location should be well ventilated and not exposed to direct
sunlight. Install the device on a non-flammable, vertical wall that does not
transmit any vibrations. Attention! Do not apply mains voltage to the output
terminals U/T1, V/T2 and W/T3.
For heat convection reasons the Bulletin 161 drive must be installed
vertically. Observe the specified minimum distances to the side walls or other
devices. Objects that come into contact with the inside of the drive may
result in the device being damaged.
If installed in normal environmental conditions (max. 40°C ambient) there must
be a minimum of 20 mm clearance around all sides of the drive to enable the
user or installer to open the front cover to get access to the terminals.
The figure below shows the minimum required clearances in case the Bulletin
161 is installed in an IP54 enclosure.

air circulation
When carrying out work on the Bulletin 161 drive please ensure that no objects
such as cable insulation, metal filings or dust get into the enclosure. This
can be avoided by covering up the non-energized AC drive.
Temperatures may not exceed or go below the permissible temperature range from
-10 to +40°C (or to +50°C in the following cases: reduction of the reference
frequency to 2 kHz; reduction of the output current to 80% Bulletin 161 drive
rated current; removal of the top cover). The higher the ambient temperature,
the shorter the life of the drive.
Do not install the device in the vicinity of devices that radiate heat.
If installing the device in a control cabinet, pay attention to the size and
heat transfer capability of the control cabinet. A fan may have to be
installed.

Disconnecting or connecting the motor, changing the number of poles in pole-
changing motors or changing the direction of rotation by means of an external
device (e.g. contactor) is not permitted during operation. Connecting
capacitive loads is not permitted. A variety of cable types are acceptable for
the drive installation. For many installation, unshielded cable is adequate,
provided it can be separated from sensitive circuits. If you cannot separate
motor cables from sensitive circuits, or if you must run motor cables from
multiple drives (more than three) in a common conduit or cable tray, shielded
motor cable is recommended to reduce system noise. (refer to Appendix A). In
the case of motor lead lengths > 50 m, output reactors should be used.
Earth the drive carefully in accordance with the instructions. Avoid the use
of shared protective earth conductors if several Bulletin 161 drives are used.

4.2 Connection and description of the control terminals
When using the transistor outputs 11, 12 – CM2 install a recovery diode
parallel to the relay used. Otherwise the switching relay could damage the
output. Do not short-circuit the terminals H and L or P24 and L.
The control wires must be installed separately from the power lines and motor
lines. They may not exceed 20 m in length. To improve noise immunity, the
control wires should be screened (refer to Appendix A). If unavoidable,
transpositions between the power lines or motor lines and the control wires
should be installed at right angles.

Bulletin 161
Appendix A: CE Conformity
The Bulletin 161 is CE marked for conformity to the Low Voltage (LV) Directive 73/23/EEC when installed as described. It also has been tested to meet the Council Directive 89/336/EEC Electromagnetic Compatibility (EMC).
The standards used are:
LV
EN50178, EN60204-1, EN60950
EMC
Emissions: Immunity:
EN61800-3 (EN55011, Group 1, Class B) EN61800-3 (Industrial Environment).
Important:
The conformity of the drive and filter to any standard does not guarantee that the entire installation or machine will conform. Many other factors can influence the total installation and only direct measurements can verify total conformity. It is therefore the responsibility of the machine manufacturer or end user to ensure that conformity is met.
General Notes and Instructions:
The motor cable should be kept as short as possible in order to avoid
electromagnetic emission as well as capacitive currents. The cable length
increases the capacitive current and electromagnetic emission.
It is recommended that the motor cable length does not exceed 50 m.
It is always recommended to install output reactors if the cable length
exceeds 50 m.
The filters contain capacitors between the phases and the phases to ground as
well as suitable discharging resistors. But after switching off the line
voltage wait a minimum of 60 seconds before removing protective covers or
touching terminals to avoid an electric shock. The use of ground fault
monitoring devices (RCD’s) is not recommended. If unavoidable only monitoring
devices which are suited for DC-, AC- and HF-ground currents (type B RCD’s)
should be used. It is recommended to use devices which responsiveness and time
characteristics are adjustable, to avoid nuisance tripping during power up the
drive.
The thermal capacity of the line filter is guaranteed up to a maximum motor
cable length of 50 m.
The line filters have been developed for use in grounded systems. Use in
ungrounded systems is not recommended.
Essential requirements for a conforming EMC installation
1. An input line filter module (see table below) must be installed to reduce conducted emissions.

Compliance of the Bulletin 161 drive to the conducted emissions levels with appropriate line filter module is as follows:
PWM Carrier Frequency <16 kHz <5 kHz <16 kHz
Motor cable length 10 m 20 m 50 m
Limit Class B Class B Class A
2. All motor cables must be shielded cable, or be in grounded metal conduit.
3. All control and signal wiring must use shielded cable or be in grounded
metal conduit.
4. Grounding of equipment and cable shields must be solid, with low impedance
connections.
5. Ensure that the protective conductor terminal (PE) of the filter is
properly connected with the protective conductor terminal of the drive. The
filter must be solidly and permanently connected with the ground potential to
avoid electric shock.

General instructions for an EMC compliance installation
Enclosure
· Typical IEC metal enclosures are adequate. · The ground connection of the
enclosure must be solidly connected to the PE terminal of the drive. Good
conductivity must be assured grounding must provide a low impedance path for
high frequency signals. · All wiring, except input power leads, must be
shielded cable. · Input power, output power and control wiring inside the
enclosure must be physically separated. · Input power, output power and
control wiring outside the enclosure must use separate shielded cables
or separate metal conduit.
Cable Clamps
· Use suitable EMC cable clamps. · The connection area must be 360 degrees
around the shielded cables. · When using conduit, the contact point of metal
must be free of paint or non-conductive surfaces
and solidly connected with good conductivity to the enclosure.
Motor Cable
· The cable between the drive and motor must be 4-wire shielded cable (three
phases and ground). · Do not exceed the maximum motor cable length for the
specific line filter module used. · Inside the enclosure, shielded motor cable
should be used as close to the drive’s output terminals
as possible. · Where the shielded motor cable exits the enclosure, an EMC
cable clamp, or metal conduit must be used
to solidly connect the cable shield to the enclosure. · The shield on the
motor side must be solidly connected to the motor housing with an EMC cable
clamp,
or conduit, providing good conductivity from the cable shield to the motor
housing.
Control Wiring
· Control wiring must use shielded cable or grounded metal conduit. · The
shield must be connected to PE at both ends of the cable. · Inside the
enclosure, shielded control wiring should be connected as close to the drive’s
control terminals
as possible.
