Should the cable gland design allows, connect cable shields to the gland to avoid threading the cable
braiding into the device housing. Do never connect cable shields to the earthing potential (ground) of
electronic boards.
Cable shields must be insulated and slightly protrude from the cable gland inside the device interior. Do
never connect shields to any terminal of the electronic device.
A detailed description of the preparation of the cable and connecting the cable to the
detector is provided in Appendix [9].
On the side of the control unit, screens must be connected to ground.
According to good practice, wiring of the detectors should be carried out as far as possible from the power
cables / high-current cables, preferably in separate trays.
The electric circuits of the Gas Safety System is not intrinsically safe. Damage of any cable
can lead to a danger.
If the connection was made with the use of multi-wire cables (commonly known as a "cord"), the ends of
these connectors should be ended with clamp sleeves.
If there is a need to connect two conductors in one terminal of the device, the only allowable option is to
connect them in a common clamping sleeve (see Table 10).
It is unacceptable to combine in one connector two wires which are not pinched in one cable
lug.
Do not place the cable reserve in the device. Bare wires or wires surplus may create a danger
of electric shock or equipment damage.
Do not leave disconnected cables inside the device.
Incorrect cable routing can lead to reducing the device's immunity from electromagnetic
interference.
Unused screw terminals must be tightened home.
