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.
Follow the electric wiring diagram for electrical wiring
works.
Form the wires and fix the cover fimmly so that the
cover may be fit in properly.

- Do not connect wires of different gauge to the same
power supply terminal. (Looseness in the connection
may cause overheating.)
Use the correct screwdriver to tighten the terminal
screws. Small screwdrivers can damage the screw
head and prevent appropriate tightening.
Over-tightening the terminal screws can damage the
screws.
