Caution: Turn the mains power supply switch off and
detach the power cord before replacing input fuses!

Open the fuse compartment by inserting a small flat-
blade screwdriver into the slot at the top of the power
module. Twist the screwdriver 1/8 turn to release the
cover, then pull out the hinged compartment, which
opens out.

Insert the screwdriver above the arrow on one fuse
cassette, catch the cassette end, and slowly slide it
completely out of the module.
Important! Fuses protect equip-
ment by disconnecting loads too
large for the instrument’s circuit
design, so it is imperative that
fuses are replaced only with fuses
of identical rating. The mains
power module, located at the back
of the power lid, contains two
input fuses:
115 V~ model:
T 3A 250 V, 5 × 20 mm
230 V~ model:
T 1.6A 250 V, 5 × 20 mm
