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 conventio ns will be use d:
• parameter names will appear in
• selection tags for inputs and outputs will appear in [brackets] (example: [RS], [CF1])
ATTENTION
• This Bulletin 161 drive generates dangerous electrical v oltages and controls potentially dangerous
rotating mechanical parts. Disregarding the guidelin es provided in this manual may re sult 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 sw itches 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

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 continuall y - Rockwell Automation

When using the transistor outputs 11, 12 - CM2 install a recovery dio de parallel to the relay used. O therwise
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 se paratel y from the power lines and m otor lines. They may not exce ed 20

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: EN61800-3 (EN55011, Group 1, Class B)
Immunity: 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 em is sion.
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 Motor cable length Limit
<16 kHz 10 m Class B
<5 kHz 20 m Class B
<16 kHz 50 m 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.
