Chapter 2 Installation and Wiring 2.2 Wiring ! WARNING - Be sure to ground the inverter. Otherwise, you run the risk of electric shock or fire. - Commit wiring work to a qualified electrician. Otherwise, you run the risk of electric shock or fire. - Before wiring, make sure that the power supply is off. Otherwise, you run the risk of electric shock or fire. - Perform wiring only after installing the inverter. Otherwise, you run the risk of electric shock or injury. - Do not remove rubber bushings from the wiring section. Otherwise, the edges of the wiring cover may damage the wire, resulting in a short circuit or ground fault. ! CAUTION - Make sure that the voltage of AC power supply matches the rated voltage of your inverter. Otherwise, you run the risk of injury or fire. - Do not input single-phase power into the inverter. Otherwise, you run the risk of fire. - Do not connect AC power supply to any of the output terminals (U, V, and W). Otherwise, you run the risk of injury or fire. - Do not connect a resistor directly to any of the DC terminals (PD, P, and N). Otherwise, you run the risk of fire. - Connect an earth-leakage breaker to the power input circuit. Otherwise, you run the risk of fire. - Use only the power cables, earth-leakage breaker, and magnetic contactors that have the specified capacity (ratings). Otherwise, you run the risk of fire. - Do not use the magnetic contactor installed on the primary and secondary sides of the inverter to stop its operation. - Tighten each screw to the specified torque. No screws must be left loose. Otherwise, you run the risk of fire. - Before operating, slide switch SW1 in the inverter, be sure to turn off the power supply. Otherwise, you run the risk of electric shock and injury. - Since the inverter supports two modes of cooling-fan operation, the inverter power is not always off, even when the cooling fan is stopped. Therefore, be sure to confirm that the power supply is off before wiring. Otherwise, you run the risk of electric shock and injury. 2 - 5
