Configuring the EMC Filter
Frame 10 size drives are equipped with common mode capacitors and
capacitors that are connected to the input terminals. 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 .
•
Must disconnect the small capacitors from the input terminals - refer to
Disconnect the Small Capacitors from the Input Terminals on page 8 .
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 .
•
Must disconnect the small capacitors from the input terminals - refer to
Disconnect the Small Capacitors from the Input Terminals on page 8 .
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 .
•
Must disconnect the small capacitors from the input terminals - refer to
Disconnect the Small Capacitors from the Input Terminals on page 8 .
