Страница: 15 / 28

6. Power supply
MULTICAL® 402 can be powered by a built-in lithium battery or by an
integral 24 VAC or 230 VAC mains module.
The two wires from battery or mains module are mounted in the calcula-
tor via a two-contacts connector.
6.1 Battery supply
MULTICAL® 402 is connected to a lithium battery, D-cell or
2 x AA-cells.
Optimal battery lifetime is obtained by keeping the battery temperature
below 30 °C, e.g. by wall mounting.
The voltage of a lithium battery is almost constant throughout the life-
time of the battery (approx. 3.65 V). Therefore, it is not possible to de-
termine the remaining capacity of the battery 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 de-struction,
f.inst. at Kamstrup A/S.
6.2 Mains 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 mounting of cable relief.
Max. permitted fuse: 6 A
National installation regulations must be obeyed.
