MULTICAL® 62 • Water meter
3 Power supply
MULTICAL® 62 can be powered by means of a built-in lithium battery or 24 VAC or 230 VAC mains
supplied via an integral supply module.
The two cables from battery or supply module are mounted in the calculator’s terminal strip.
The polarity must be correct:
red cable to terminal no. 60 (+)
black cable to terminal no. 61 (-)
3.1 Battery supply
MULTICAL® 62 is connected to a lithium battery, D-cell. The battery is marked with installation year,
e.g. 2014 as well as production date.
Kamstrup type number: 66-00-200-100.
Optimal battery lifetime is obtained by keeping the battery temperature below 30 °C.
The voltage of a lithium battery is almost constant throughout the lifetime of the battery (approx.
3.65 V). Therefore, it is not possible to determine the remaining capacity by measuring the voltage.
The battery cannot and must not be charged and must not be short-circuited!
Used batteries must be handed in for approved destruction, e.g. at Kamstrup A/S.
3.2 Supply modules
The modules are protection class II and are
connected via a two-wire cable (without earth)
through the cable bush of the calculator placed
in the right side of the connecting base.
Use connecting cable with an outer diameter
of 5-10 mm and ensure correct dismantling as
well as correct cable relief.
Max. permitted fuse: 6A.
National regulations for electric installations
must be observed.
