9、Notice
●No responsibility for problems occurred by disassembly privately;
●Please make sure reliable connection to avoid fault tripping or damage of terminals caused by exceptional heat;
●Don’t use hand to touch the exposed non-insulated part when the circuit breaker is powered.
●No responsibility for problems occurred by debugging the circuit breaker’s characteristic optionally.
●Simulating test should be made once a month by pressing the test button to check whether the circuit breaker works normally. If RCBO is abnormal, it should be replaced.
