1. Important Safety Information WARNING! Before installing and using the Inverter, you need to read Following safety information carefully. 1-1. General Safety Precautions 1-1-1. Do not expose the Inverter to water, mist, snow, or dust. To reduce the risk of hazard, do not cover or obstruct the ventilation shaft. Do not install the Inverter in a zero-clearance compartment.
3. Instructions This power inverter series is one of the most advanced line of mobile AC power systems. To get the most effective power inverter, it must be installed and used properly. Please read the instructions of this manual before you install and operate this model.

3-2-2. Ventilation Shaft: Be sure to keep it a distance (at least 1 inch) form surrounding things. 3-2-3. Input terminals: Connect the input terminal to 12V / 24V / 48V battery or other 12V / 24V /48V power source. 【+】represents positive, and【-】represents negative. Reverse polarity connection will blow the internal fuse and may damage the inverter permanently.
3-3. Installation: The power inverter should be installed in an environment that meets the following requirements: 3-3-1. Dry – Do not allow water to drip on or enter into the inverter. 3-3-2. Cool – Ambient air temperature should be between 0℃ and 33℃, the cooler the better.
3-4. Quick hook – up and testing: For a quick hook – up of the power inverter to check its performance before going ahead with installation, please follow these guidelines: 3-4-1. To check its performance, unpack and inspect the power inverter the switch is OFF.

3-4-3. Before proceeding further, carefully check that cable you have connected does tie negative terminal of inverter to the negative output power source. CAUTION ! Reverse polarity connection will blow the fuse in inverter and may permanently damage the inverter. Damage caused by reverse polarity connection is not covered by warranty.
3-5. AC Safety Grounding: During the AC wiring installation, AC input and output ground wires are connected to the inverter. The AC input ground wire must be connected to the incoming ground from AC utility source. The AC output ground wire should go to the grounding point for your loads ( for example, a distribution panel ground bus ).
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 with 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.

Increasing DC cable size helps improve the situation. Cotek recommends the following cables for optimum inverter performance. (apply both 120V and 230V versions) Model No Wire AWG Inline Fuse S600-112 100A S600-212 100A S600-124 S600-224 Also, use only high quality copper wiring and keep cable length short, (a maximum of 3-6 feet).
3-7. Inverter Operation: To operate the power inverter, use the ON / OFF switch on the Front panel to turn the power on. Then the power inverter is ready to deliver AC power to the loads. If you are operating several loads from the power inverter, turn them on separately after the inverter is on.
4. Troubleshooting: WARNING! Do not open or disassemble the S600 Inverter. Attempting to service the unit yourself may cause an electrical shock or fire. Problems and Symptoms Possible Cause Solutions Low output voltage Using average reading Use true RMS reading meter and cable.
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 pre vent accumulation of dust and dirt. At the same time, tighten the screws on the DC input terminals.
