using a measuring voltage of 1 kV DC. The insulation resistance must be higher than
1 Mohm.
Checking the compatibility with IT (ungrounded) systems
EMC E200 is not suitable for use in an IT (ungrounded) system. If the drive is
equipped with E200, disconnect the filter grounding wire before connecting the drive
to the supply network. Insulate the end of the wire and attach it. The wire is located behind
the middle front cover.
WARNING!
If a drive with EMC E200 is installed on an IT system (an
ungrounded power system or a high resistance-grounded [over 30 ohm] power
system), the system will be connected to earth potential through the EMC filter
capacitors of the drive. This can cause danger, or damage the drive.
