The installation wiring enters the terminal compartment via a single M20 Ex e cable gland,
which can be mounted on either side of the compartment. The unused entry is blanked with
an Ex e cover.
The detector housing must be connected to local ground via the external earth
point. The wire should be minimum 4 mm2 (8 AWG) and as short as possible.
The shield of the cable should be connected at both sides (at detector side and at the
controller). The shield must be terminated to local ground via the cable gland at the detector
and must not enter the terminal compartment.
