2.4 Connecting the detector
It is recommended to use a stranded, 3 wire cable with a conductor cross section from 0.75
to 1.5mm².
The terminals coming from each detector must be connected to the U•H1 unit in the
following order:

The cables that connect the detector and the U•H1 unit should not be more than 300 m
long.
If the U•H1 unit is installed in an environment that contains sources of strong
electromagnetic interference (transmitters, welding stations, switching relays, HF
transmitters, cable runs or computer networks, etc.), it is preferable to use shielded cables
to connect the detector.
Never use two or more wires to increase the cross-sectional area of the wire. The cable
must be one length of cable (without connections) and properly connected to the
appropriate terminals. Use a maximum torque of 0.60 Nm.
Never place a detector cable next to a coaxial cable or a power cable and never in the
same bundle or cable run.
2.5 Connecting the power supply
Connect the earth to terminal 3 and then the 230V mains voltage to terminals 1 and 2 on
the terminal; see the box below.
