Be sure to follow the precautions below when turning off the circuit breaker.
• Precautions for turning off the circuit breaker

MAINTENANCE. Note if the Mode switch is set to any other position and the circuit
breaker is turned off, the partition may turn on automatically the next time the circuit breaker
is set to On.
l Never turn on the circuit breaker again within 10 seconds after the circuit breaker is turned
off.
• Precautions for automatic shutdown of the circuit breaker
l If the circuit breaker is automatically shut down as current overload is found, this means
there is abnormality in the power line of the main unit, such as short circuit. Turning on the
circuit breaker too soon after such a shutdown may shut down the breaker of the distribution
panel. Using without appropriate problem resolution may cause overcurrent in the main
unit. Therefore, if such shutdown occurred, consult with a certified service engineer for
maintenance.
