4.2 Power Supply

4.2.2 Noise Filter Installation
Insert the three-phase noise filter into the primary station of the fuse disconnect switch if you
hear noise coming from the power source.
Seal up each cable opening so that dust does not enter.
4.2.3 Leakage Breaker Installation
When connecting the leakage breaker to the controller power supply wiring, use a leakage
breaker which can handle high frequencies from the NX100 inverter. Leakage breakers which
cannot handle high frequencies may malfunction.
For the leakage breakers, select UL-approved products.
Even with a leakage breaker installed, there is still a possibility of some high frequency current
leakage from the NX100 inverter. But, this current leakage presents no safety risks.
