- Page 2 The advanced surge capacity of the PI-400 power invert- er gives it the means to start most electrical appliances including: Color televisions, TV/VCR combinations, microwaves, refrigeration units, small air conditioners. In addition, the PI-400 power inverter consumes less bat- tery power, therefore runs for a longer time because it is a state-of-the-art microprocessor-controlled inverter.
- Page 3 ON (I), OFF (0), and ON (I) again in quick succession. If this procedure is not successful, it is likely that the PI-400 inverter does not have the required capacity to operate the appliance in question.
- Page 4 D. 12-Volt Power Cord E. High-Speed Cooling Fan F. (2) 25-Amp Fuses How To Connect your PI-400 Inverter Make sure the ON/OFF rocker switch is in the OFF (0) position. (If connecting in a vehicle, remove the ciga- rette lighter from its outlet.) Push the 12-volt power plug firmly into the outlet.
- Page 5 You can use an extension cord from the inverter to the appliance without significantly decreasing the power being generated by the inverter. For best operating results, the extension cord should be no longer than 50 feet. The LED Indicator briefly flashing when you first turn the inverter ON, is a sign if that there is a short circuit within the power supply.
- Page 6 3. Install the new fuse (supplied with your power inverter.) Attention: Do not install a fuse higher than 25-amps, as this may damage the inverter. Make sure to correct the cause of the blown fuse before using the PI-400 again.

Page 7: Power Source
Power Source Your average automobile or marine battery will provide an ample power supply to the inverter for 30 to 45 minutes even when the engine is off. The actual length of time the inverter will function depends on: 1. Age and condition of the battery. 2. - Page 8 400 watts. 4. The case temperature exceeds 145 ºF. Attention: The PI-400 is fitted with a cooling fan that runs as needed while the inverter is operating. If the cooling fan is unable to maintain a cool enough tempera- ture for safe operation, the inverter will automatically shut down.
- Page 9 There are two stages involved in transforming 12-volt DC (or battery) power into 110V AC (household voltage): STAGE 1: The PI-400 power inverter uses a DC to DC transformer to increase the 12-volt DC input voltage from the power source to 145-volts DC.

Make sure the power consumption of the appliance or equipment you want to operate is compatible with the capacity of the inverter, i.e. does not exceed 400 watts. If you are using the power inverter to operate battery charger, monitor the temperature of the battery charger for about 10 minutes. - Page 11 PROBLEM: Red LED On Reason/Solution 1. Battery voltage below 11 volts. Recharge or replace battery. 2. Equipment being operated is drawing too much power. Use a higher capacity inverter or do not use this equipment. 3. Inverter is too hot (thermal shut down mode). Allow inverter to cool.
