Caution!
If an external set-value potentiometer is connected, this resistor must be removed.

4.7 Replacing the fuses
The fuses protect the controller from non-permissible operating
conditions. After the release of such a protective function, the
controller and the system must be checked for further faults before
replacing the fuses.
Remove the protective cover to replace the fuses.
Caution!
Removal of the protective cover and the replacement of the
fuses must only be carried out by qualified skilled personnel
when no voltage is applied.
Defective fuses must only be replaced by the prescribed type (see
chapter 2.1 "Controller-specific data").
The protective cover must be attached again after the fuses are
replaced.
