Precautions on electrical wiring work

High voltage
To avoid electrical shock, make sure to disconnect the
power supply 1 minute or more before servicing the
electrical parts. Even after 1 minute, always measure the
voltage at the terminals of main circuit capacitors or
electrical parts and, before touching, make sure that those
voltages are 50 V DC or less.
Use only copper wires.
For W1
Make sure to connect power supply cables in normal phase. If
connected in reverse phase, the remote controller indicates " U1 "
and the equipment cannot operate. Change any two of the three
power supply cables (L1, L2, L3) to correct 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 figure 2
so that it does not come in contact with the piping, particularly
on the high-pressure side.
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.
NOTE The earth leakage circuit breaker must be a high-
speed type breaker of 30 mA (<0.1 s).
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.
