The battery is located on the CCU module (see Fig. 9-1). Before withdrawing
the CCU module, please comply with the ESD measures in the preface of this
Planning Guide.
Warning
The modules contain electrostatic sensitive components. Before touching an
electronic module, the persons carrying out the work must themselves be
electrostatically discharged. The simplest way of doing this is to touch an
electrically conducting earthed object (e.g. a bare metal part of a switchboard
or a plug socket protective conductor).
1. Shut off the control.
2. Comply with the ESD note !
3. Loosen all connectors, marking them first, if necessary.
4. Loosen the four CCU module fastening screws and take out the module.
5. Remove the battery and pull out the battery connector. A c apacitor will back
up the data for approx. 15 mins.
6. Connect the new battery (check polarity) and push it back into the bracket.
7. Re-insert the CCU module and tighten the screws.
8. Insert all the connectors correctly.
