exhaustive.
SYMPTOM
POSSIBLE CAUSE/SUGGESTED
ACTION
Upon initial power-up, the converter does not
behave in accordance with the Section 6.1
description (no display, LEDs, or fans).
Ensure dock power is available. Check
pedestal and shore cord circuit breakers.
Have input power to the converter
checked by a qualified electrician.
Have the power supply fuses located at
the converter base just behind the front
cover checked by a qualified electrician.
Have the main power supply checked
by a qualified electrician.
Upon initial power-up, no fan activity is heard
or otherwise detected.
Have the fan power supply checked by
a qualified electrician.
The converter powers-up in accordance with
the Section 6.1 description, but does not accept
a SHORE POWER ON button press.
Review SHORE POWER metering at
the converter for a single (or dual) shore
input(s) between 170-520VAC.
The converter does not accept a CONVERTER
POWER ON button press.
Review
CONVERTER
POWER
metering at the converter for the correct
and expected output voltages.
The converter does not accept a SHIP’S
POWER CONVERTER or SHIP’S POWER
GENERATOR button press (if the Seamless

The converter trips to a SHORE POWER OFF
state unexpectedly and reports the message
“INPUT_OVERLOAD”
Review Section 7.7. Clear the kW-
