Power Supply CBA Bottom View
Because a hot chassis ground is present in the power supply
circuit, an isolation transformer must be used when repairing.
Also, in order to have the ability to increase the input slowly,
when troubleshooting this type of power supply circuit,
a variable isolation transformer is required.
BA01P0F01033
NOTE:
The voltage for parts in hot circuit is measured using
hot GND as a common terminal.
For continued protection against risk of fire,
replace only with same type 8A, 250V fuse. CAUTION ! :
ATTENTION : Utiliser un fusible de rechange de m ê me type de 8A, 250V.
8A 250V
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.
Otherwise it may cause some components in the power supply circuit to fail.
