When inserting a circuit breaker between the robot and the AC input power supply, select the circuit breaker with breaking capacity higher than the following specification. Use a high frequency-proof leakage breaker for inverters.
- Recommended circuit breaker example : CP33V/20 (Fuji Electric FA Components & Systems Co., Ltd.)
Using a circuit breaker with breaking capacity lower than the following specification may cause the circuit breaker to be shut down due to robot operation.
CAUTION: Take preventive measures against any electrical hazards, such as electric shock, caused by leakage current or grounding fault.
For countermeasures, refer to the following points.
- Use an earth leakage circuit breaker.
- Refer to EN 60204-1 (European Norm
