Using a multimeter set on the AC volts scale,
measure the voltage between the blue and
brown wires at the inline fuse connectors.
Normal voltage is between 216 and 264VAC.
Using a multimeter set on the DC volts scale,
measure the voltage between red and grey wires
at terminal I on the control PCB.
Normal voltage is between 144V and 192V DC.
