9.7 Exchanging the supply unit
The power supply unit for MULTICAL
®
602 can be exchanged from mains supply to battery or vice versa as the needs
at the utility change. In this way, mains supplied meters can be exchanged for battery meters with advantage in
connection with buildings in the course of construction, as the mains supply may be unstable or lack periodically.
Previous versions of MULTICAL
®
602 (before 2014-04-01) use screw terminals for connection of the supply unit.
When replacing the supply unit in previous versions, cut off the plug and strip the cable insulation before
connecting the cables to the screw terminals.
Exchange from battery to mains supply does not require reprogramming, as MULTICAL
®
602 does not contain an
information code for worn out batteries.
However, exchange from mains supply to battery must not be made on MULTICAL
®
602 with the following base
modules:
