20 Secure the electrical wiring with cable ties as shownin the figure in 10.2 . Make sure no external pressure is applied to theterminal connectors. When installing the earth leakage circuit breaker makesure that it is compatible with the inverter (resistant tohigh frequency electrical noise ) to avoid unnecessaryopening ofthe earth leakage circuit breaker. As this unit is equipped with an inverter, installing aphase advancing capacitor not only will deterioratepower factor improvement effect, but also may causecapacitor abnormal heating accident due to high-frequency waves. Therefore, never install a phaseadvancing capacitor.CAUTIONBe sure to install the required fuses or circuitbreakers.10.2.

When cables are routed from the unit, a protectionsleeve for the conduits (PG-insertions) can beinserted at the knock-out hole. When you do not use a wire conduit, be sure toprotect the wires with vinyl tubes to revent the edge ofthe knock-out hole from cutting the wires.
