SOLID
RED
SOLID RED -
AC fail, charger
fail or
overvoltage
shutdown
1. Charger is in a fault
state
2. Charger failure
AC LED
1. Using a voltmeter, check that
AC input voltage and frequency at
AC input terminal block/breaker
are in the range 188VAC
–
428VAC / 47Hz
–
63Hz or that >
60VDC is present at DC output
terminal block/breaker and that
the DC polarity is correct. Correct
charger AC input and DC output
voltage as required.
2. If step 1 doesn’t resolve RED AC
light, remove both AC and DC
power for 1 minute, then reapply
power.
3. If steps 1 and 2 don’t resolve
RED AC light, a charger failure is
the likely cause. Replace charger.
DC LED
1. Remove AC and DC power from
charger for 1 minute before
reapplying power. Ensure AC
voltage and/or DC voltage is
within specified operating limits
of the charge.
2. If fault remains, check
overvoltage shutdown settings
and again remove both AC and DC
power for 1 minute, then reapply
power.
3. If steps 1 and 2 don’t resolve
issue, a charger failure is the likely
cause. Replace charger.

AC LED
1. Using a voltmeter, check that
AC input voltage and frequency at
AC input terminal block (J100) are
in the range 188VAC
–
428VAC /
47Hz
–
63Hz or that >60VDC is
present at DC output terminal
block/breaker and that the DC
polarity is correct. Correct charger
AC input and DC output voltage as
required.
2. If step 1 doesn’t resolve RED AC
light, remove both AC and DC
power for 1 minute and then
reapply power.
3. If
steps 1 and 2 don’t resolve
RED AC light, a charger failure is
the likely cause. Replace charger.
