6 Replacing components
6.1 Accessing SCPC System modules
6.1.1 Externally accessible modules
It is not necessary to open the SCPC System to replace the following modules:
◗ Battery monitoring circuit board
◗ Mains monitoring circuit board
◗ Sensor modules
Battery monitoring (ZAU 2002) and Mains monitoring (ZNU 2003)
The layout of these circuit boards conforms to the description on page 6.47. Other parts of the casing
do not need to be opened.
Notes on replacing individual components on these circuit boards (e.g. fuses, EPROM) can be found in
chap. 6.9.
!
Caution: When the front panel and touch screen are removed and the housing is open there is access
to battery voltage. Remove the bridge between the batteries to reduce the risk of short circuits.
