10. Installation location
Install this device in a dry indoor location.
To function correctly, please note that the device must not be
exposed to strong electromagnetic fields.
Ensure that the heat meter can be isolated from the power supply
by an additional isolator that can separate all poles with at least
3 mm contact separation, or with an isolating facility (fuse) in
accordance with current regulations.
When installing the power cable and the sensor leads, ensure that
they are routed separately.
10.1 assembly
The device is designed for installation on finished even and vertical
walls with power connection from below.
»
Undo the centre screw and remove the panel.

10.2 Fixing
»
Transfer the two fixing holes onto the wall.
»
Drill the holes and insert rawl plugs.
»
Insert a screw into the upper hole and turn in until approx. 5 mm
of the screw head protrudes from the wall.
»
Hook the device into the gap between the screw head and the
wall, and then fully tighten the screw.
»
Position the lower screw and turn in. Ensure that the casing is
not subject to any mechanical stress.

Provide the heat meter with power via an external main isolator.
Secure the flexible cables/leads to the casing using the strain relief
provided and the appropriate screws.
The following connection allocation applies to a heat meter used
in conjunction with a volumeter (any polarity of the individual
terminals):
