6.5.4 Lithium Battery
Fig. 47: Location of the battery with open housing
A 3 V lithium battery (type CR2032) is integrated into
the SCU (Part No. 583381.31) unit to protect the
customer data. In order to ensure the protection over
the long term, this battery should be replaced after no
more than five years, such as during regular
maintenance.
To do this switch off the power supply (mains and
battery), carefully open the SCU housing, remove the
battery and replace with an identical or equivalent
battery type.
Insert the new battery, carefully close the housing,
switch on the power supply (mains and battery).
Perform a function test!
If the SCU does not start up fully following a battery change, please check whether the BIOS flash disk
is being booted. No other boot devices are permitted.
Danger – Electric shock!
Assembly and installation work may only be performed when the system is de-energised (voltage free).
ESD / EMC preventive measures
Before handling electronic modules, always take suitable precautions to prevent static electricity.
