Skyjack SJIII 4620 Operating Manual page 61

Section 3 - Operation
WARNING
Risk of electric shock – do not immerse the
charger in water. Though the charger is highly
resistant to water, it is not designed for immersion,
and an electric shock can occur.
CAUTION
Hot Surfaces - During charging, the surface of the
charger may become hot to the touch, especially
in higher ambient temperatures. This is normal.
Avoid touching the surface of the charger.
1. Provide adequate ventilation for the batteries and
charger.
NOTE
The convection cooled design requires access
to cooling air for proper operation. Do not allow
blankets or other materials to cover the charger.
Although the charger protects itself against
overheating, the charger cooling fins should
be cleaned if clogged with debris for best
performance.
WARNING
There could be a spark during charging. Be
careful when using fuels, solvents or other
flammables near the charger or batteries.
2. Connect the power supply cord to a properly
grounded socket between 100 to 240 VAC, 50/60
Hz. The charger automatically senses and adjusts
to the AC input voltage range.
3. The charging time is affected by numerous factors
including the battery Amp-Hour capacity, depth
of discharge, battery temperature, and battery
condition (new, old, or defective). Batteries larger
than 240 AH can be recharged but will take longer.
WARNING
Do not disconnect the DC output wires near the
batteries when the charger is ON. The resulting
arcing could cause the batteries to explode. If the
charger must be disconnected, first disconnect
the AC power supply cord from its outlet, then
disconnect the charger DC connections.
SJIII DC Electric
WARNING
Risk of an electric shock – do not touch
uninsulated parts of the charger output wires,
battery connector, or battery terminals.
WARNING
Visually and manually inspect to verify the DC
output wires and terminals are in good working
condition before each use.
4. The charger will start automatically within four
to six seconds. The charger will start even with
severely discharged batteries (down to 1 V
terminal voltage). Once the charging starts, the
LEDs indicate the charging progress.
Batteries do not fully charge: If the batteries
▪
are charged overnight, make sure the AC supply
is not being switched off at night with other
building items. Check the battery condition and
for dead cells or reduced capacity. Replace the
charger only if other problems are not found.
The AC line circuit breaker or fuse is blown: A
▪
defective circuit breaker or fuse, an overloaded
circuit, or a charger problem can cause this
condition. Try connecting the charger to a
different AC outlet (on a different circuit) in
the building. If the AC supply is sufficient, the
charger should be replaced.
