5.2.1 Installing residual current circuit breakers (optional)
For connection of an all-current sensitive ELCB use a switch suitable for the high frequency
of the robot controller inverter. Leakage breakers which cannot handle high frequencies
may malfunction.
Tab. 5-1: Example of High Frequency Leakage Breaker
Even with a leakage breaker installed, there is still a possibility of some high frequency
current leakage from the robot controller.
However, this current leakage presents no safety risks.
