Replacing Fuses

The R&S

 

ZCPS is protected by two time lag fuses (IEC60127-2/5 T3.15H / 250 V,

stock no. 0099.6729.00), located in the fuse drawer below the AC power switch
on the rear panel (see 

figure 2-2

).

Shock hazard

Before replacing a fuse, make sure that the instrument is switched off and
disconnected from all power supplies.
Always use fuses supplied by Rohde & Schwarz as spare parts, or fuses of
the same type and rating.

To replace the fuses

1. Use a small screwdriver to bend the small clamps on both sides of the fuse

drawer inward so that you can lift the fuse drawer out of its slot.

2. Exchange the fuses.

3. Push the drawer back into the slot.
