12 ACS880-01/04 +C132 marine type-approved drives
Electrical installation

IT (ungrounded) networks
The ground-to-phase varistor of the drive is not suitable for use on an IT
(ungrounded) system. Disconnect it (also from marine type-approved drives with
E201) before you connect the drive to the supply network. For disconnecting
instructions, see
EMC filter and ground-to-phase varistor disconnecting instructions
for ACS880 frames R1 to R11 (3AUA0000125152 [English]) or contact ABB.
WARNING! Do not install the drive with the ground-to-phase varistor
connected on an IT system (an ungrounded power system or a high-
resistance-grounded [over 30 ohms] power system). The varistor circuit and the drive
can be damaged.
