8.13 Outdoor Fan System Check
Check No.19
8.14 Capacitor Voltage Check
Check No.21 Before this check, be sure to check the main circuit for short circuit.
With the circuit breaker still on, measure the voltage according to the drawing of the model in
question. Be careful never to touch any live parts.
To prevent electrical shock, use a tester to check that the voltage between P (+) and N (–) is
50 V or less.
The surface of the test points (P, N) may be covered with the coating. Be sure to make firm
contact between the tester probes and the test points.
