Checking fuses/MCB

For fuse locations, see from page 78.
■ Fuse F1 is located on the cross con-

nect PCB.

■ Fuse F3 is located on the main PCB.

Fuses F1 and F3:
■ 6.3 AH (slow), 250 V~
■ Max. power loss

≤

2.5 W

Danger

Contact with 'live' components
can lead to serious injury from
electric current.
Before working on the equip-
ment, always ensure that

the

power circuit is also at zero
volt.

Removing the fuse from the cross
connect PCB does

not switch

the power circuit to zero volt
