In the event of a suspected Power Module failure, examine the LED at the upper left corner of
each Power Module. With SHORE POWER in the ON state, the LEDs should all be lit. If any
Power Module’s LED is not lit, turn OFF the adjacent switch (down for OFF) which will disable
that Power Module. The converter can then be used at a reduced power level (75% load for three
Power Modules, and 50% for two Power Modules) until such time as a replacement module is
available. If the bottom Power Module switch must be turned OFF, please contact an authorized
service center or the factory.

POWER MODULE FUSES
If a Power Module failure has occurred, it is possible that one or more of Fuses F11-18 may now
be open. These fuses are located behind the input and output connection panel on the upper right
side.
