8.13 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.
50/65/80 class
To prevent electrical shock, use a multimeter 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 multimeter probes and the test points.
