Before opening the BENNING PV 1-1, make quite sure that it is voltage free!
Electrical danger!
The BENNING PV 1-1 is protected against overload by means of one built-in fuse (500 mA,
1000 V, F, D = 6.3 mm, L = 32 mm) (P.no.749771).
Proceed as follows to replace the fuse (see Figure 10):
- Switch the BENNING PV 1-1 off.
- Put the BENNING PV 1-1 face down and unscrew the screw of the battery compartment
cover.
- Lift off the battery compartment cover (in the area of the housing slots) from the bottom part
of the battery compartment.
- Laterally lift one side of the defective fuse off the fuse holder by means of a slotted screw-
driver.
- Completely remove the defective fuse from the fuse holder.
- Insert the new fuse. Only use fuses of the same nominal current, nominal voltage, nominal
breaking capacity, tripping characteristic and dimensions.
- Lock the battery compartment cover into place on the bottom part and tighten the screw.
