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
controller inverter. Leakage breakers which cannot handle high
frequencies may malfunction.
Even with a leakage breaker installed, there is still a possibility of some
high frequency current leakage from the controller inverter. However, this
current leakage presents no safety risks.
