3-2 GV6000 AC Drive User Manual
3.1.1 Verifying Power Module Input Ratings Match Available Power
GV6000 AC Drives are suitable for use on a circuit capable of delivering a maximum of
200,000 rms symmetrical amperes, and a maximum of 600 volts (nominal).
3.1.1.1 Unbalanced or Ungrounded Distribution Systems
For ungrounded distribution systems, disconnect the MOVs and common mode
capacitors by removing or disconnecting the jumper(s) shown in figure 3.1.
!
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 section 4.4.
!
ATTENTION: GV6000 AC Drives contain protective MOV’s and
common mode capacitors that are referenced to ground. These devices
should be disconnected if the drive is installed on an ungrounded
distribution system. To guard against drive damage, these devices should
be disconnected if the drive is installed on an ungrounded distribution
system where the line-to-ground voltages on any phase could exceed
125% of the nominal line-to-line voltage. Failure to observe this
precaution could result in damage to, or destruction of, the equipment.
ATTENTION: To avoid electrical shock hazard, verify that the voltage
on the bus capacitors has discharged before removing/installing jumpers.
Measure the DC bus voltage at the +DC terminal of the Power Terminal
Block and the -DC test point. The voltage must be zero.
