AC CIRCUIT CHECKOUT PROCEDURE
FOR DUAL INPUT VOLTAGE CHARGERS
Check for proper input voltage to primary of transformer. Set meter to read AC voltage.
ACTION
MEASURE
IF
THEN
Step 1 - Set AC voltage selection switch
to proper position.
Step 2 - Place AC voltage test leads of
meter at wall receptacle.
Measure voltage
100-130 volts AC
or
200-260 volts AC
No
Check wall breaker.
Step 3 - Remove charger cover.
Step 4 - Place one meter test lead on
the IEC320 socket terminal that is
connected to a brown wire. Place the
other meter test lead on the IEC320
socket terminal that is connected to a
blue wire.
Step 5 - Plug AC cord into wall
receptacle. Measure voltage and
unplug.
Measure voltage
100-130 volts AC
or
200-260 volts AC
No
Replace AC cord.
Step 6 - Move meter test leads to
voltage selection switch terminals
where the brown and blue wires are
connected.
Step 7 - Plug AC cord into wall
receptacle. Measure voltage and
unplug.
Measure voltage
100-130 volts AC
or
200-260 volts AC
No
Check connections
from IEC320 socket to
voltage selection
switch.
Step 8 - Move the meter test lead at
the voltage selection switch terminal
with a brown wire to the circuit
breaker (referred to as the first circuit
breaker) terminal that is connected to
the voltage selection switch. Leave the
other meter test lead as in Step 6.
Step 9 - Plug AC cord into wall
receptacle. Measure voltage and
unplug.
Measure voltage
100-130 volts AC
or
200-260 volts AC
No
Check connections
from the voltage
selection switch to the
first circuit breaker.
