4. Mounting of calculator
The MULTICAL® 602 calculator can be mounted in three different ways:
4.1 Compact mounting
The calculator is mounted direct on the flow sensor, e.g. via an angle fitting. Having
been mounted the calculator is sealed with seal and thread. In case of strong
condensation (e.g. cooling applications) we recommend wall mounting of the
calculator.

≤
DN100", page 6.
4.2 separate/wall mounting
52 mm
In connection with mounting in condensing environments as well
as in order to prolong the battery lifetime, we recommend the use
of a wall fitting.
The wall fitting makes it possible to mount MULTICAL® 602 direct
on an even wall. Use the fitting as a template to mark and drill two
6 mm holes in the wall.
4.3 Panel mounting
MULTICAL® 602 can be mounted direct in panels and control panels, via Kamstrup's
panel mounting kit, No. 66-99-104 (192 x 144 mm).
5. Electrical connection, MULTICAL® and ULTRAFLOW®
The polarity of temperature sensors T1, T2 and T3 is unimportant.
For flow sensors V1 and V2 the below-mentioned colours are used
when connecting ULTRAFLOW® and electronic pick-up units.
Flow sensors with reed switch output are connected to terminals
11–10 and 11–69 respectively.
