MULTICAL® 603

5.5  Connection of other flow sensors

Other passive flow sensors with either reed switch or transistor 
output can be connected to MULTICAL® via the terminal numbers 
in the table. Be aware of correct mounting of + and - of flow 
sensors with transistor outputs.

Some types of MULTICAL® can be connected to other flow 
sensors with 24 V active pulse outputs using the terminal 
numbers in the table. Be aware of correct mounting of + and -.

5.6  Connection of power supply

5.6.1  Battery supply

MULTICAL® can be delivered battery-supplied with a number of various batteries. 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 lifetime of the battery (approx. 3.65 
VDC). Therefore, it is not possible to determine the remaining capacity of the battery by measuring 
the voltage. However, the information code of the meter indicates if the battery level is low, see 
the paragraph “Information code”. 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. 
Further details appear from document on handling and disposal of lithium batteries (5510-408).

5.6.2  Mains supply

MULTICAL® is available with supply modules for either 24 VAC* or 230 VAC.
The supply modules are protection class II and are connected via a two-wire cable (without earth) 
through the big cable bush at the bottom of the connection base. Use connecting cable with an 
outer diameter of 5-8 mm and ensure correct cable stripping as well as correct mounting of cable 
relief. If connecting to 230 VAC, it is important to make sure that the whole installation complies 
with current regulations. MULTICAL® can be delivered with 2 x 0.75 mm² supply cable. The supply 
cable for the meter must never be protected by a fuse larger than the one permitted.
In case of doubt, it is recommended to take advice from an authorised electrician and get an 
individual assessment of the execution of the installation in question. In addition, note that work 
on fixed installations and any intervention in the fuse box, must be carried our by an authorized 
electrician only.
For installation in Denmark: See “Installation of mains connected equipment for registration of 
consumption” from the Danish National Safety Board.
*  By use of a 24 VAC/VDC “high-power” supply module, MULTICAL® can also be supplied from 24 

VDC.

5.7  Internal communication

According to type, MULTICAL® 603 has the possibility of internal M-Bus communication, M-Bus is 
connected via the connection PCB using terminals 24 and 25.
