Because a hot chassis ground is present in the power
supply circuit, an isolation transformer must be used.
Also, in order to have the ability to increase the input
slowly,when troubleshooting this type power supply
circuit, a variable isolation transformer is required.
CAUTION ! :
For continued protection against risk of fire,
replace only with same type 4 A, 125V fuse.
4A 125V
ATTENTION : Utiliser un fusible de rechange de même type de 4A, 125V.
CAUTION !
Fixed voltage (or Auto voltage selectable) power supply circuit is used in this unit.
If Main Fuse (F1601) is blown , check to see that all components in the power supply

circuit are not defective before you connect the AC plug to the AC power supply.
(END-SENSOR)
Otherwise it may cause some components in the power supply circuit to fail.

NOTE:
The voltage for parts in hot circuit is measured using
hot GND as a common terminal.
