4. Route AC power input cable in through knock-out
provided in side panel of charger cabinet. Securely
fasten cable wires to a power input terminal inside
charger. Refer to Grounding section of this manual
for proper connection of grounding conductor.
(Charger cabinet top or side panel, or both, may
have to be removed to provide access to terminal
block.)
5. With disconnect switch (on AC input power line) in
“OPEN” or “OFF” position, connect power cable
coming from charger, to the switch. Install fuses in
switch.
Charging Cable Connectors
If connectors are already attached to charging cables,
make sure that they’re attached so that positive charger
polarity will connect to positive battery terminal.
If connectors must be attached to charging cables,
follow instructions supplied with connectors.
CAUTION: Make sure connectors are
securely attached to cables (good
solder joint or well tightened set screws,
whichever is applicable). Be certain
that positive charger cable will connect
to positive battery terminal. If necessary,
trace cables into charger and use
supplied connection diagram to
determine polarity. The use of a DC
voltmeter may show polarity. Improper
connections will “blow” output fuse
and may cause other damage.
Pre-operation Checks
1. Inspect charger thoroughly for damage; loose
screws, nuts, or electrical connections.
WARNING: ELECTRICAL SHOCK
HAZARD – Before inspecting or
cleaning inside cabinet, turn OFF
and remove fuses of disconnect
switch (supplying AC power to
charger), disconnect battery, and
check for voltage on capacitors.
Discharge through insulated
screwdriver if there is any reading.
2. Remove all special tags that are tied to charger.
Keep tags with this manual for future reference.
Leave all precautionary and instruction labels in
place on charger. Carefully read and follow
instructions on all tags and labels. Make sure all
labels remain visible to anyone operating charger.
3. Make sure all charger cabinet panels are fastened
in place, to assure proper flow of ventilating air
through cabinet.
