Corner-grounded and midpoint-grounded 525…690 V delta systems
WARNING!
Do not install the drive on a 525…690 V corner-grounded or midpoint-grounded
delta system. Disconnecting the EMC filter and ground-to-phase varistor does
not prevent damage to the drive.
■
When to disconnect EMC filter (oE200 and +E202) or
ground-to-phase varistor: TN-S, IT, corner-grounded delta and
midpoint-grounded delta systems and TT systems
Requirements for disconnecting EMC filter and varistor and additional requirements for
different electrical power systems are given below.
Symmetrically grounded TN systems (TN-S systems (ie. center-grounded wye)
Do not disconnect EMC or VAR screws.
