10 Maintenance
Products by Lutz-Jesco are manufactured to the highest quality stand-
ards and have a long service life. However, some parts are subject to op-
erational wear. This means that regular visual inspections are necessary
to ensure a long operating life. Regular maintenance will protect the de-
vice from operation interruptions.
DANGER!
Mortal danger from electric shock!
Live parts can inflict fatal injuries.
ð
Before carrying out any maintenance work, always disconnect the
device from the power supply.
ð
Secure the system to prevent it from being switched on by accident.
WARNING!
Increased risk of accidents due to insufficient qualifica-
tion of personnel!
The system and its accessories may only be installed, operated and
maintained by personnel with sufficient qualifications. Insufficient
qualification will increase the risk of accidents.
ð
Ensure that all action is taken only by personnel with sufficient and
corresponding qualifications.

10.4 Battery
The device is fitted with a button cell. Check the button cell within the
scope of the annual maintenance. The lifetime of the button cell is deter-
mined by the device usage and can vary considerably.
You will need to replace the battery more often with devices which are
switched off often or over a long period (e.g. over winter).
