CAUTION: Read all operating instructions before operating the power pack.
The power pack is not intended for use as a UPS (Uninterruptible Power
Supply). The unit should be operated only in locations that meet the
following requirements:
Dry
Don’t allow water or other liquids to drop or splash on the unit.
Cool Ambient air temperature should be between -10° and 40° C
(14° and 104° F) – the cooler the better within this range.
Ventilated Leave at least 2” (5 cm) clearance around the unit for air flow.
Ensure that the ventilation openings are not obstructed.
Safe Do not operate the unit in the same compartment as batteries
or in any compartment capable of storing flammable liquids
like gasoline.
Protect from Do not operate the unit where it will be exposed to battery
battery gases gases. These gases are very corrosive and prolonged exposure
will damage the power pack
AC appliances
The power pack has one grounded AC power outlet for use with AC
appliance. You can either plug the appliance directly into the AC outlet or you
can use an AC power bar to increase the number of outlets available.
However, for continuous operations, the combined loads must be less than
80W. The less wattage used, the longer the power pack will operate before
recharging is required.
Operating range:
• 80 watts or less for continuous operation
• 100 watts for 5-minute operation
Some appliance may be difficult or impossible to operate from the power
pack. They may have high surge requirements or may be incompatible with
the output waveform of the power pack. See “High Surge Appliances” and
“Trouble Appliances” (page 10).
NOTE: To determine required wattage for a device, look up required Amps a
device is rated. This Amperage is found on device I.D. tag in back of the unit.
Multiply Amps X Volts = Watts.
Some devices you can power up:
• 13” TV (80W)
• Video Game System (20W)
• Weather Radio (10W)
Operating AC appliances
1. Check battery status to ensure the battery is fully charged.
2. Open the AC Outlet cover.
3. Turn the AC socket switch ON.
4. Plug the AC appliance into AC outlets.
5. Turn the AC appliance ON.
6. Recharge the power pack immediately after use. See “recharging the
power pack battery” (page 12).
Low battery shut down
Unit will automatically shutdown when the battery reaches 10.0V DC. You must
turn off the AC power switch and charge the battery.
Overload and high temperature protection
In the event of an overload (>100W) or overheating, the power pack
automatically shuts down power to the AC outlets. If, after a while the audible
warning is ignored and a manual reset is not performed, the unit will do a
complete shutdown automatically.
High surge appliances
The wattage rating of AC appliance is the average power used by the appliance.
Appliances such as televisions, computer monitors and appliances with motors
consume much more power than their average rating when they are first
switched on.
Although power pack can supply momentary surge power up to 400W, some
appliances may exceed the capabilities of the power pack and trigger the
inverter’s safety overload shutdown circuit.
