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, see 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 the drive Technical Data
publications. See Additional Resources on page 17
for a list of technical
publications for PowerFlex 700H and PowerFlex 700S drives.
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.
