 Use only copper wires .
 A main switch or other means for disconnection, having a contact separation in all poles, must be
incorporated in the fixed wiring in accordance with applicable legislation . Do not turn on the main switch until
all the wiring is completed .
 Make sure to connect power supply cables in normal phase .
 Never squeeze bundled cables into a unit .
 Fix cables so that cables do not make contact with the pipes (especially on high pressure side) .
 Secure the electrical wiring with cable ties as shown in the figure in 10 .2 .
 Make sure no external pressure is applied to the terminal connectors .
 When installing the earth leakage circuit breaker make sure that it is compatible with the inverter (resistant to
high frequency electrical noise ) to avoid unnecessary opening of the earth leakage circuit breaker .
 As this unit is equipped with an inverter, installing a phase advancing capacitor not only will deteriorate power
factor improvement effect, but also may cause capacitor abnormal heating accident due to high-frequency waves
. Therefore, never install a phase advancing capacitor.
Be sure to install the required fuses or circuit breakers.
