Configuring the EMC Filter
Frame 11 size drives are equipped with common mode capacitors. To guard
against drive damage, these capacitors should be disconnected depending
upon the type of ground system on which the drive is installed.
Installation on an Ungrounded Distribution System or High Resistive Ground
If you are installing a 400/480V AC input drive on an ungrounded
distribution system or high resistive ground, you:
•
Must move the common mode jumper to the disconnected position -
refer to
Move the Common Mode Jumper to the Disconnected
Position on page 6 .
•
Should insulate terminal X4 on the Rectifier circuit board- refer to
Insulate Terminal X4 on the Rectifier Circuit Board on page 7 .
If you are installing a 600/690V AC input drive on an ungrounded
distribution system or high resistive ground, you:
•
Must move the common mode jumper to the disconnected position -
refer to
Move the Common Mode Jumper to the Disconnected
Position on page 6 .
•
Must insulate terminal X4 on the Rectifier circuit board- refer to Insulate
Terminal X4 on the Rectifier Circuit Board on page 7 .
Installation on a Grounded B Phase Delta System
If you are installing a drive on a grounded B phase Delta system, you:
•
Must move the common mode jumper to the disconnected position -
refer to
Move the Common Mode Jumper to the Disconnected
Position on page 6 .
•
Must insulate terminal X4 on the Rectifier circuit board- refer to Insulate
Terminal X4 on the Rectifier Circuit Board on page 7 .
Note: Refer to Wiring and Grounding Guidelines for Pulse Width
