WARNING: All work on the opened device is only permitted
in a de-energized state. The device must not be switched on
again during work!
WARNING: For explosion-proof actuators, it is necessary
to wait a certain time after switching off before opening the
cover (see Operating Instructions for SMARTCON Control
Units).
In order to be able to maintain the function of the real-time clock as well as the counter readings of the con-
troller even in a de-energized state, it has a button cell battery. The service life of this battery varies depending
on the ambient conditions, and must be replaced if necessary, at the latest as soon as the control unit issues
the relevant warning (see Operating Instructions for SMARTCON Control Units).
For replacement, pry the battery out of the socket using a plastic lever tool. Make sure that the tool is not
placed under the socket, as this may cause damage to the circuit board. Then replace the battery with the
following characteristics:
• Model Number: CR2032
• Electrochemical System: MnO
• Nominal Voltage: 3V
• Rated Capacity: 225mAh

8 Fuses
