ATTENTION: The drive can operate at excessive armature voltage and speed if
J30 is improperly set to the LOW position when it should be set to HI.
This jumper is factory set according to the type of Power Interface module installed in the drive.
jumper positions are labeled LOW and HIGH. For WebPak 3000 drives with a nominal voltage
rating AC 575 V, 60 Hz and 690 V, 50 Hz the jumper J30 must be set to HIGH, for all other
drives this jumper must stay in position LOW. Please refer to the ‘AC Input’ data on the
nameplate.
If this jumper is not set to the correct position nuisance AC line voltage high/low alarms may
occur or, if configured as a voltage regulator, the drive will not operate at the correct speed.
