3 INSTALLATION
3.2.9 Electrical wiring, wall-mounted, 13-30 VDC, with or without relay
Before wiring the device, please read § 3.2.1, 3.2.2, 3.2.3, 3.2.4 and 3.2.7
carefully.
Install the device as described in § 3.1.2. Unscrew the 4 screws of the cover and unscrew
the cable glands. Pass the cables through the cable glands by preferably respecting the
allocation indicated in § 3.2.8.
Connect the terminals according to the pin assignment described below.
- Only manipulate the switches when the device is not powered.
- Make sure switches "SENSOR SUPPLY", "FLOW SENSOR" and
"SENSOR INPUT LOAD" are correctly positioned according to the
separate sensor version (see § 3.2.3 and 3.2.4).
