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:
Refer to 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.
