- Only properly trained and qualified personnel are allowed to perform wiring work.
- Before wiring, be sure to shut off the power supply. Never perform wiring work
while the product is energized.
- Supply power of the product should meet the specifications on page 7-1.
- Ensure a stable power supply with no voltage surges.
- Take care not to overload the power supply by connecting multiple units to one
supply.
- Supply power from a system that has emergency stop measures.
- Ensure that a Ground Fault Circuit Interrupter (GFCI) with appropriate capacity for
earth leakage and load is used in the power supply of the product to prevent
electrical shock and burnout of the compressor motor. See “7-1 List of
sp
ecifications” for details.
- Be sure to install the circuit breaker correctly so that it disconnects all live
conductors and so that the operating handle can be easily accessible.
- Circuit breaker must be properly selected to meet safety standard of local
regulations.
- The product must be grounded for safety.
- Be sure that the protective conductor has some additional length in respect to the
live conductors, so that it is not subject to mechanical stresses.
- Always be sure to connect the protective conductor first, disconnect it last in
respect to the other connections.
- Do not connect ground wire to a water pipe, a gas pipe, or a lightening rod.
- Do not modify the electrical wiring of the power supply.
