15. TROUBLESHOOTING
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.
In case a problem occurs, first check wiring connector connections.
