The 2 Amp charger incorporates fuses on both the
input ac line and the battery charger output. The
input AC line fuse is a Littelfuse 2 Amp, Slo-Blo Fuse,
5x20mm, P/N 218002. The AC line fuse is located on
the charger printed-circuit board. The output DC bat-
tery fuse is a Littelfuse 5 Amp, Mini-Blade Fuse, P/N
297005. The battery fuse is located on the charger
printed-circuit board.
The 10 Amp charger incorporates fuses on both the
input ac line and the battery charger output. The
input AC line fuse is a Littelfuse 5 Amp, Slo-Blo Fuse,
5x20mm, P/N 218005. The AC line fuse is located
on the charger printed-circuit board. The output DC
battery fuse is a Littelfuse 15 Amp, ATO Fuse, P/N
257015. The battery fuse is located on the charger
printed-circuit board.
These chargers require that the battery be connected
to the charger in order to turn on. The battery voltage
must also be above a certain "boost" voltage for the
charger to turn-on.
The boost voltage required is approximately 11 volts
for a 12V system. If the battery open-circuit voltage is
less than the above boost voltage, it is recommended
that the battery be checked.
If the voltage of the generator's 12V battery exceeds
15VDC, during normal charging operation, the bat-
tery should be checked. Typical battery voltages,
when a 12V battery is being charged, should be in the
13VDC to 15VDC range.
The 2 Amp and 10 Amp chargers are UL recognized
for use in the R-panel enclosure and are not to be
operated outside the R-panel enclosure.
DANGER
Storage batteries give off explosive hydrogen
gas. This gas can form an explosive mixture
around the battery for several hours after charg-
ing. The slightest spark can ignite the gas and
cause an explosion. Such an explosion can shat-
ter the battery and cause blindness or other
injury. Any area that houses a storage battery
must be properly ventilated. Do not allow smok-
ing, open flame, sparks or any spark producing
tools or equipment near the battery.
Battery electrolyte fluid is an extremely corro-
sive sulfuric acid solution that can cause severe
burns. Do not permit fluid to contact eyes, skin,
clothing, painted surfaces, etc. Wear protective
goggles, protective clothing and gloves when
handling a battery. If fluid is spilled, flush the
affected area immediately with clear water.
Do not use any jumper cables or booster battery
to crank and start the generator engine. If the
battery has completely discharged, remove it
from the generator for recharging.
Be sure the AUTO/OFF/MANUAL switch is set to
the OFF position, before connecting the battery
cables. If the switch is set to AUTO or MANUAL,
the generator can crank and start as soon as the
battery cables are connected.
Be sure the utility power supply to the battery
charger is turned off, or sparking may occur at
the battery posts as the cables are attached and
cause an explosion.
