4.1 Power Supply System
4.1.1 The AC power is absent.
1. Initial checks
[1] Is the power plug connected to the power outlet?
[2] Is the rated AC voltage present at the power outlet?
[3] Has the leakage breaker gone ON?
2. Switch PCB, Wiring, Connector
Is the resistance 0 Ω when the switch is turned on and ∞Ω when it is turned
off?
NO:
YES: Check the AC power line (power cord, leakage breaker, switch
