General Installation Information
AC Supply Source
Considerations
Frame 9 - 14 PowerFlex 700H and 700S drives are suitable for use on a
circuit capable of delivering up to a maximum of 200,000 rms symmetrical
amperes, and a maximum of 690 volts.
If a system ground fault monitor (RCD) is to be used, only Type B
(adjustable) devices should be used to avoid nuisance tripping.
Unbalanced, Ungrounded or Resistive Grounded Distribution Systems
If phase to ground voltage will exceed 125% of normal or the supply system
is ungrounded, refer to Wiring and Grounding Guidelines for Pulse Width
Modulated (PWM) AC Drives, publication DRIVES-IN001…, for more
information.

ATTENTION: To guard against personal injury and/or
equipment damage caused by improper fusing or circuit breaker
selection, use only the recommended line fuses/circuit breakers
specified in Appendix A
.
!
ATTENTION: PowerFlex 700H and 700S drives contain
protective MOVs and common mode capacitors that are
referenced to ground. These devices must be disconnected if the
drive is installed on a resistive grounded distribution system or an
ungrounded distribution system.
