1. Important Safety Information WARNING! Before installing and using the Inverter, you need to read the following safety information carefully. 1-1. General Safety Precautions 1-1-1. Do not expose the Inverter to rain, snow, spray, bilge or dust. To reduce risk of hazard, do not cover or obstruct the ventilation openings.
2. Features Pure sine wave output (THD < 3%) Output frequency:50 / 60Hz switch selections Input & output completely isolated design High efficiency 84~94% Capable of driving inductive & capacitive loads at the start moment. A LED Indicator with twin color displays all operation status. Loading and temperature controlled cooling fan.
3. Instructions This power inverter series is a the member of the most advanced line of mobile AC power systems available. To get the most out of the power inverter, it must be installed and used properly. Please read the instructions in this manual before installation and operation this model.

3-4-6. Close to batteries – Avoid excessive cable lengths but do not install the Inverter in the same compartment as batteries. Use the recommended wire lengths and sizes (see section 3-5). Also do not mount the Inverter where it will be exposed to the gases produced by the battery.
3-6. AC Safety Grounding: The AC output ground wire should go to the grounding point for your loads ( for example, a distribution panel ground bus ). 3-6-1. Neutral Grounding (GFCI’S): 3-6-1-1. 120V models:The neutral conductor of the AC output circuit of the Inverter is automatically connected to the safety ground during inverter operation.
Ground Fault Circuit Interrupters (GFCI): Installations in Recreational Vehicles (for North American approvals) will require GFCI protection of all branch circuit connected to the AC output of the hardwire terminal equipped Inverter. In addition, electrical codes require GFCI protection of certain receptacles in residential installations. While the pure sine wave output of the Inverter is equivalent to the waveform provided by utilities, compliance with UL standards requires us to test and recommend specific GFCI.
4. Troubleshooting guide: WARNING! Do not open or disassemble the Inverter. Attempting to service the unit yourself may result in a risk of electrical shock or fire. Problems and Symptoms Possible Cause Solutions “No AC Power Output” STATUS illuminates the red LED a.
5. Maintenance: Very little maintenance is required to keep your inverter operating properly. You should clean the exterior of the unit periodically with a damp cloth to prevent accumulation of dust and dirt. At the same time, tighten the screws on the DC input terminals. 6.
