9.14 Inverter Board Layout ( Bottom Side )

CAUTION !

Fixed voltage (or Auto voltage selectable) power supply circuit is used in this unit.
If Main Fuse (F1901) 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.

For continued protection against risk of fire,
replace only with same type 4 A, 125V fuse.

CAUTION ! :

ATTENTION :

ê

me type de 4A, 125V.

4A/125V

Because a hot chassis ground is present in the power
supply circut, 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.

NOTE:

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