IT (ungrounded) systems
A drive equipped with no EMC filter or with EMC filter +E210 is suitable for IT
(ungrounded systems). If the drive is equipped with EMC filter +E202, disconnect
the filter before connecting the drive to an ungrounded system. For detailed
instructions on how to do this, please contact your local ABB representative.
WARNING! If a drive with EMC filter +E202 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.
