In case a problem occurs, first check wiring connector connections.
In order to prevent electric shock and short circuit, be sure to turn power off
before performing work.
Be careful so as not to damage wirings. Damaged wiring can cause electric
shock or short circuit.
After removing the cause of the functioning of the Circuit Protector, reinstate
the Circuit Protector. Depending on the cause of the functioning, using the
Circuit Protector as is without removing the cause can cause generation of
heat and fire hazard.
