Power Supply Block Diagram

E7B22BLP

CAUTION !

Fixed voltage (or Auto voltage selectable) power supply circuit is used in this unit.

If Main Fuse (F1001) 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.

NOTE:

The voltage for parts in hot circuit is measured using

hot GND as a common terminal.

CAUTION !

For continued protection against fire hazard,

replace only with the same type fuse.
