Ground-To-Phase Varistor - ABB ACS880-14 Schnellinstalationsanleitung

Make sure that the drive is compatible with the grounding
system
The standard drive with ground-to-phase varistors connected can be installed to a
symmetrically grounded TN-S system. If you install the drive to another system, you
may need to disconnect the EMC filter and ground-to-phase varistors. See
frames R1 to R11 EMC filter and ground-to-phase varistor disconnecting instructions
(3AUA0000125152 [English]).
EMC filter options +E200 and +E202
￭
Do not install the drive with EMC filter +E200 or option +E202 connected to a
system that the filter is not suitable for. This can cause danger, or damage the
drive.
Note: When EMC filter +E200 or +E202 is disconnected, the drive EMC compatibility
is considerably reduced.

Ground-to-phase varistor

￭
A drive with the ground-to-phase varistor connected can be installed to a symmetrically
grounded TN-S system. If you install the drive to another system, you may need to
disconnect the varistor. See
varistor disconnecting instructions (3AUA0000125152
Do not install the drive with the ground-to-phase varistor connected to a system
that the varistor is not suitable for. If you do, the varistor circuit can be
damaged.
