Frame 14 Mechanical Installation Chapter 10
Ungrounded, High Resistive
Ground or Grounded B Phase
Delta Installations Frame 14 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.
To access and move the common mode jumper(s) and disconnect the capacitor
connections you must first move the control frame and remove the protective
covers from the converter unit. These steps are detailed on the following pages.
Note: See Wiring and Grounding Guidelines for Pulse Width Modulated
(PWM) AC Drives - Installation Instructions, publication
DRIVES-IN001 , for
additional information on an ungrounded distribution system or high resistive
ground installation.
