The Power Source:
When the engine is off, most batteries will provide an ample power supply
to the Inverter for one to two hours. The actual length of time is a function
of several variables including the age and condition of the battery, and the
power demand being placed on it by the equipment being operated.
If you are using the Inverter while the engine is off, we recommend you
start the engine every hour and let it run for approximately 10 minutes to
recharge the battery. We also recommend that the device plugged into the
Inverter be turned off before turning over the engine.
Although it is not necessary to unplug the Inverter when starting the
engine, the Inverter may momentarily cease operation as the battery voltage
decreases. When the Inverter is not supplying power, it draws very low
amperage from the battery (< 0.1 amps to < 0.2 amps depending on the
model) and may be left connected to the battery for up to 3 hours. However,
we recommend the Inverter always be disconnected when not in use.
Note:
• Inverters will not operate with certain automotive systems unless the
ignition is on. If the Inverter is not generating power, try turning the
ignition to the accessory position.
Automatic Shut-down and Related Safety Features:
The Belkin 140 and 300-Watt Inverter models have a unique LED indicator
warning light system that operates in conjunction with the automatic shut
down feature. This indicator light operates as follows:
RED - Overload/Low Battery
Your Inverter will shut down automatically when any of the following
problems occur:
1. The power input from the battery drops below 10.4 volts.
2. The power output from the battery exceeds 15 volts.
3. The continuous draw of the device exceeds the design
parameters of the Inverter.
