Inspect the circuit breaker to see
if it has tripped off.
( If it is tripped off….like diagram B,
reset the breaker. And check which
part is short-circuited. Then replace
the short-circuited part.)
2. The switch is turned to the "ON" position.
( If the switch light isn't lit, replace the switch.)
Verify wire connection AC1 & AC2 on the MCB.
( refer to “wiring diagram”…….page 4-3 )
Verify the ON/OFF switch, breaker & socket wires are connected.
