Additional Information Regarding Power Requirements
DC Power Source Requirements:
The Inverter must be connected only to batteries with a nominal output voltage
of 12 Volts. The unit will not operate from a 6-Volt battery and will be damaged
if it is connected to a 24-Volt battery. The power source must provide between
11–15.5 Volts DC. The power source may be a battery or other well-regulated
12V DC power supply. Check your vehicle’s owner manual.
The power supply must also be able to deliver the amperage necessary to
operate the load created by the AC product. As a rough guideline, divide the
power consumption of the load (in Watts) by 12 (the input voltage) to obtain
the current (in Amps) the power source must deliver. Example: If the AC televi-
sion is rated at 120 Watts; the power source must be able to deliver:
(120/12) = 10 Amps. Most vehicular 12V cigarette lighter outlets have fuses
that will permit the outlet to draw 20 Amps.
AC Power Draw Guidelines:
Most electrical tools, appliances and audio/video equipment have labels that
indicate the power consumption in Amps or Watts. Be sure that the continuous
power consumption of the item(s) you wish to operate is rated at 120 Watts or
less. If the power consumption is rated in Amps, simply multiply by the AC volts
(115) to determine the wattage. For example, a power drill rated at 1 Amp will
draw 115 Watts. Do not use the Inverter to operate product(s) that require more
than 120 Watts of continuous power.
Fuse Replacement
If the Inverter is overloaded and the (20A) fuse is blown, unplug the Inverter
to replace the automotive type 20A fuse in the cigarette lighter plug which is
accessed by unscrewing the knurled chrome trim piece at the end of the plug.
If the cigarette lighter outlet fuse in your vehicle has blown, unplug the
Inverter. Follow the vehicle manufacturer’s instructions for replacing the fuse,
and replace the fuse only with the identical rating and type of fuse.
Using any
other fuse can result in serious or fatal injury and property damage.
Determine the cause of the overload/short circuit before restarting
your Inverter.
