These products comply with the Low Voltage Directive 2006/95/EC, the Electromagnetic Compatibility Directive
2004/108/EC.
These electronic drive products are intended to be used with appropriate motors, controllers,
electrical protection components and other equipment to form complete end products or
systems. Compliance with safety and EMC regulations depends upon installing and
configuring drives correctly, including using the specified input filters. The drives must be
installed only by professional assemblers who are familiar with requirements for safety and
EMC. The assembler is responsible for ensuring that the end product or system complies
with all the relevant laws in the country where it is to be used. Refer to the User Guide. An
EMC Data Sheet is also available giving detailed EMC information.
Declaration of Conformity (including 2006 Machinery Directive)
This declaration applies to Unidrive M variable speed drive products, comprising models numbers as shown below:
This declaration relates to these products when used as a safety component of a machine. Only the SAFE
TORQUE OFF function may be used for a safety function of a machine. None of the other functions of the
drive may be used to carry out a safety function.
These products fulfil all the relevant provisions of Directive 2006/42/EC (The Machinery Directive).

IMPORTANT NOTICE
These drive products are intended to be used with appropriate motors, sensors, electrical protection
components and other equipment to form complete systems. It is the responsibility of the installer to
ensure that the design of the complete machine, including its safety-related control system, is carried out
in accordance with the requirements of the Machinery Directive and any other relevant legislation. The use
of a safety-related drive in itself does not ensure the safety of the machine.
Compliance with safety and EMC regulations depends upon installing and configuring inverters correctly.
The inverters must be installed only by professional assemblers who are familiar with requirements for
safety and EMC. The assembler is responsible for ensuring that the end product or system complies with
all the relevant laws in the country where it is to be used. Refer to the User Guide.

4 Electrical installation
An overlay of the electrical connections / terminals is included on the back page of this manual.
4.1 AC supply requirements
Voltage:
100 V drive: 100 V to 120 V ±10 %
200 V drive: 200 V to 240 V ±10 %
400 V drive: 380 V to 480 V ±10 %
Number of phases: 3
Maximum supply imbalance: 2 % negative phase sequence (equivalent to 3 % voltage imbalance
between phases).
Frequency range: 48 to 62 Hz
For UL compliance only, the maximum supply symmetrical fault current must be limited to 100 kA.
4.2 External braking resistor
4.2.1 Minimum resistance values and peak power rating for the braking resistor
at 40 °C (104 °F)
Table 4-1 Braking resistor resistance and power rating (100 V)
On the size 2 110 V drives or when connecting single phase to a dual rated 200 V unit, the
supply should be connected to L1 and L3.
Overload protection
When an external braking resistor is used, it is essential that an overload protection device
is incorporated in the braking resistor circuit; as shown in the electrical diagram on the
back cover.

4.3.1 Use of residual current device (RCD)
There are three common types of ELCB / RCD:
1. AC - detects AC fault currents
2. A - detects AC and pulsating DC fault currents (provided the DC current reaches zero at least
once every half cycle)
3. B - detects AC, pulsating DC and smooth DC fault currents
• Type AC should never be used with drives.
• Type A can only be used with single phase drives
• Type B must be used with three phase drives
The above leakage currents are just the leakage currents of the drive with the internal
EMC filter connected and do not take into account any leakage currents of the motor or
motor cable.
When the internal filter is installed the leakage current is high. In this case a permanent
fixed ground connection must be provided, or other suitable measures taken to prevent a
safety hazard occurring if the connection is lost.
When the leakage current exceeds 3.5 mA, a permanent fixed ground connection must be
provided using two independent conductors each with a cross-section equal to or
exceeding that of the supply conductors. The drive is provided with two ground
connections to facilitate this. Both ground connections are necessary to meet EN 61800-
5-1: 2007.
Only type B ELCB / RCD are suitable for use with 3 phase inverter drives.

Issue Number: 4
If an external EMC filter is used, a delay of at least 50 ms should be incorporated to ensure spurious
trips are not seen. The leakage current is likely to exceed the trip level if all of the phases are not
energized simultaneously.
4.4 Control terminal configurations and wiring
This parameter is used to automatically setup the user programmable area in the level 2 parameter
set according to drive configurations. Other default values may also be changed by drive
configuration. Parameters are stored in EEPROM automatically following a configuration change.
Defaults are loaded before drive configuration changes are made. Defaults loaded are defined by
Defaults Previously Loaded (11.046).
Action will only occur if the drive is inactive, not in UU state and no User Actions are running.
Otherwise, the parameter will return to its pre altered value on exit from edit mode. All parameters
are saved if this parameter changes.

4.5 EMC
4.5.1 Internal EMC filter
It is recommended that the internal EMC filter be kept in place unless there is a specific reason for
removing it. If the drive is used as a motoring drive as part of a regen system, then the internal EMC
filter must be removed.
The internal EMC filter reduces radio-frequency emission into the line power supply.
For longer motor cables, the filter continues to provide a useful reduction in emission levels and
when used with any length of shielded motor cable up to the limit for the drive, it is unlikely that
nearby industrial equipment will be disturbed. It is recommended that the filter be used in all
applications unless the instructions given above require it to be removed, or where the ground
leakage current is unacceptable.
4.5.2 Removing the internal EMC filter
Figure 4-11 Removal of the internal EMC filter (size 2 shown)
To electrically disconnect the internal EMC filter, remove the screw as shown above (1).
4.5.3 Further EMC precautions
Further EMC precautions are required if more stringent EMC emission requirements apply:
• Operation in the first environment of EN 61800-3: 2004
• Conformity to the generic emission standards
• Equipment which is sensitive to electrical interference operating nearby
In this case it is necessary to use:
• The optional external EMC filter
• A shielded motor cable, with shield clamped to the grounded metal panel
The supply must be disconnected before removing the internal EMC filter.
