The power repeaters and field bus power supplies are products in the KF housing of
Pepperl+Fuchs.
A special feature of the KF system is the removable ter-
minals. Screw-in self-opening apparatus terminals suit-
able for a conductor cross-section of up to 2.5 mm² are
integrated.
The illustration below shows the power rail versions that are used. The connection be-
tween the current-conducting leads of the power rail and the power pack of the switch
cabinet is implemented by a power feed module.
Power Rail UPR-05
Figure 7.3: Power rail variants
The UPR-05 Power Rail does not have a grid and is delivered together with a carrier
rail 2 meters in length. The UPR-05 can be shortened at any spot. The PR-05 has a
20-mm grid and is an insert component to be fitted onto a DIN rail in accordance with
EN 50022. It is supplied with a length of 50 cm and can be reduced in size at any of
the marks spaced at intervals of 4o mm.
Subject to reasonable modifications due to technical advances.

Devices of the KF system are normally installed on a 35-mm
top hat section rail in accordance with DIN EN 50022 with an
inserted power rail. The devices can simply be snapped ver-
tically onto the top hat section rail. In no case should the mod-
ule be mounted from the side so that it is slanted or tipped.
The advantage of the power rail is that power can be supplied
to the modules through it. Power can also optionally be fed in
through the terminals of the power repeater/power supply.
