Change of supply unit
The supply unit for MULTICAL
®
61 can be changed from mains supply to battery or visa versa as the needs of the
utility change. Thus, it can be an advantage to change mains supplied meters to battery supplied meters in
buildings under construction where the mains supply can be unstable or periodically missing.
The change from battery to mains supply or visa versa does not require reprogramming as MULTICAL
®
61 does not
include an information code for worn out battery.
However, mains supply must not be changed to battery if MULTICAL
®
61 is fitted with one of the following base
modules:
