IT (ungrounded) systems
In units with EMC filter options (+E202 and +E200 in the type code), disconnect the
filter capacitors before connecting the drive to an ungrounded system.
WARNING!
If a drive with EMC filter selE202 or +E200 is installed on an IT
system [an ungrounded power system or a high resistance-grounded (over 30 ohms)
power system], the system will be connected to earth potential through the EMC
filter capacitors of the drive. This may cause danger or damage the unit.
Disconnecting the EMC filter capacitors
Remove the two screws shown below.
Note:
When the EMC filter capacitors are disconnected and the motor cable is
longer than 100 m (328 ft) the EMC Directive requirements may not be fulfilled in first
environment, but are fulfilled in second environment. See chapter
.
