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: 45 to 66 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)
* Resistor tolerance: ±10 %
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. Also the DC bus (-) terminal on 110 V drives
has no internal connection. The 110 V drives use a voltage doubler circuit on the input,
therefore the default for Motor Rated Voltage (Pr 08) is 230 V.
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 Ground leakage
The ground leakage current depends upon whether the internal EMC filter is installed or not. The
drive is supplied with the filter installed. Instructions for removing the internal filter are given in
section 4.5.2 Removing the internal EMC filter on page 18.
With internal filter installed:
Size 1:
8.1 mA* AC at 110 V 50 Hz
9.5 mA* AC at 230 V 50 Hz
Size 2:
13 mA* AC at 110 V, 50 Hz (1 phase)
6.3 mA* AC at 230 V, 50 Hz (3 phase)
17.5 mA* AC at 230 V, 50 Hz (1 phase)
9.2 mA* AC at 415 V, 50 Hz (3 phase)
Size 3:
17.1 mA* AC at 230 V 50 Hz (1 phase)
5.9 mA* AC at 230 V 50 Hz (3 phase)
5.7 mA* AC at 415 V 50 Hz (3 phase)
Size 4:
21.3 mA* AC at 230 V 50 Hz (1 phase)
9.7 mA* AC at 230 V 50 Hz (3 phase)
13.3 mA* AC at 415 V 50 Hz (3 phase)
* Proportional to the supply voltage and frequency.
With internal filter removed:
Size 1: < 1 mA
Size 2: 110 V: < 1.2 mA
230 V: < 1 mA
415 V: < 2.3 mA
Size 3: 230 V: < 1.6 mA
415 V: < 1 mA
Size 4: < 1 mA
The above leakage currents are just the leakage currents of the drive 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.

Issue Number: 8
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
If an external EMC filter is used with an ELCB / RCD, 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
* With Unidrive M101, the default is PAd (5).
Action will only occur if the drive is inactive 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.
Only type B ELCB / RCD are suitable for use with 3 phase inverter drives.

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 4-9 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+A1:2012
• 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
• A shielded control cable, with shield clamped to the grounded metal panel
Full instructions are given in the Power Installation Guide.
A full range of external EMC filters are also available for use with Unidrive M100 / 101, shown in the
Power Installation Guide.
The supply must be disconnected before removing the internal EMC filter.

5.1 Saving parameters
When changing a parameter in Menu 0, the new value is saved when pressing the Enter button
to return to parameter view mode from parameter edit mode.
If parameters have been changed in the advanced menus, then the change will not be saved
automatically. A save function must be carried out.
Procedure
1. Select ‘Save' in Pr 00 or Pr mm.000 (alternatively enter a value of 1001 in Pr 00 or Pr mm.000)
• Press the red reset button
5.2 Restoring parameter defaults
Restoring parameter defaults by this method saves the default values in the drives memory. User
Security Status (Pr 10) and User Security Code (Pr 25) are not affected by this procedure.
Procedure
1. Ensure the drive is not enabled, i.e. drive is in inhibit or under voltage state.
2. Select 'Def.50’ or 'Def.60' in Pr 00 or Pr mm.000 (alternatively, enter 1233 (50 Hz settings) or
1244 (60 Hz settings) in Pr 00 or Pr mm.000).
Press the red reset button
