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