Mounting the Drive 3-3
3.1.1.1 Unbalanced or Ungrounded Distribution Systems
To disconnect the MOVs and common mode capacitors, remove the
jumper(s) shown in figures 3.1 and 3.2 and table 3.1.
!
ATTENTION: SP600 drives contain protective MOVs and
common mode capacitors that are referenced to ground. 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 electric 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.
