4.3.2. Connection of the electrical ground braid
Use a shield connection clamp (not supplied) to connect the shielding of the cable to the
electric ground of the housing (see § below).
4.3.3. Grounding
A M4 screw passes through the body of the enclosure, enabling the electronic ground of the
housing to be connected to the local ground.
It is recommended to use a yellow / green wire with a ring lug (minimum diameter 1.5 mm).
The armour of the power cable is normally connected to the ground of the detector, but it
may depend on site practices.
4.3.4. 3-wires connection(source)
For a standard 3-wires connection, the 20mA current loop must be supplied with 24 V at
terminal L+. To proceed, connect the 3 (V +) and 5 (L +) terminals at the terminal block level
of the device
