TOPs P4 live testing procedure
Mains Power On

Measurement:

Test 1:
Measure the AC voltage across pin 6 (brown) at connector X3 on the PCB to a suitable earth point.
Voltage should be approximately 240V AC.
Test 2:
Measure the AC voltage across pin 7 (blue) at
connector X3 on the PCB to a suitable earth point.
Voltage should be less than 15V AC
