MULTICAL® 602 & ULTRAFLOW®
5.3 Electricl connection of Pulse Trnsmitter
If ULTRAFLOW® 54 is used for other equipment, connection must be mde through 
Pulse Trnsmitter or Pulse Divider. See instlltion instructions No. 5512-1421 for further
informtion.
6 Voltge supply of clcultor/Pulse Trnsmitter
MULTICAL® 602 cn be powered by  built-in lithium bttery or n integrl 24 VAC or 230 VAC mins
module.
The bttery or mins module is mounted vi  two-pole plug in the clcultor terminl.
For Pulse Trnsmitter the supply module/bttery is connected vi  two-pole plug. See instlltion
instructions No. 5512-1421 for further informtion.
6.1 Bttery supply
MULTICAL® 602 is connected to  lithium bttery, D-cell. The bttery is mrked with instlltion
yer, e.g. 2014, s well s production dte.
Optiml bttery lifetime is obtined by keeping the bttery temperture below 30 °C, e.g. by wll
mounting.
The voltge of  lithium bttery is lmost constnt throughout the lifetime of the bttery (pprox.
3.65 V). Therefore, it is not possible to determine the remining cpcity of the bttery by
mesuring the voltge.
The bttery cnnot nd must not be chrged nd my only be short-circuited briefly (mx. 2
seconds). Used btteries must be hnded in for pproved destruction, e.g. t Kmstrup A/S.
6.2 Mins modules
The modules re protection clss II. They re connected by mens of  two-wire cble (without
erth) through the cble bush of the clcultor plced in the right side of the connecting bse. Use
connecting cble with 5-10 mm outer dimeter nd ensure correct dismntling s well s correct
mounting of cble relief.
Mx. permitted fuse: 6 A.
Ntionl regultions for electric instlltions must be observed.
6.2.1 High-power supply modules
These modules re glvniclly seprted from the mins supply. The modules include  Switch
Mode Power Supply (SMPS), which fulfils double-isoltion requirements when the clcultor top is
mounted. The modules re vilble in two vrints with either 24 VAC or 230 VAC connection.
