„ 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 ofthe 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.
CAUTION
Be sure to install the required fuses or circuit
breakers.

„ Secure the cable to the stop valve attachment plate
so that it does not slide.
„ When cables are routed from the unit, a protection
sleeve for the conduits (PG-insertions) can be
inserted at the knock-out hole.
„ When you do not use a wire conduit, be sure to
protect the wires with vinyl tubes to revent the edge of
the knock-out hole from cutting the wires.
