TROUBLESHOOTING
Occasional faults may occur in certain conditions. Please follow the suggested
steps.
1. Charger Does Not Power Up
When the charger is first turned on (main disconnect switch in the
ON
position),
the LCD should come on and display one of the idle mode messages, typically
the
CONNECT BATTERY
screen.
If the LCD is not illuminated after power is applied, perform the following checks:
a. Verify that the main disconnect switch is in the
ON
position.
b. Cycle the switch to the
OFF
position and then return it to the
ON
position.
c. If the charger still does not power up, carefully verify the source circuit and
wiring to the charger and correct any problems. Be sure to check that the
fuses in the AC mains junction box on the wall are intact, and also that the
supply voltage for all three phases (AC mains line-to-line) is 400
–480 V ±
10%, and matches to 10 VAC or better.
DANGEROUS VOLTAGES AND CURRENTS ARE PRESENT IN THE AC MAINS

CHECKS, USING PROPER EQUIPMENT AND PROCEDURES.
