Installing the docking station

— If the transmitter is to be installed in a Zone 2 explosion-hazard area, select
a location with low exposure to mechanical risk.
— Docking station is installed vertically (transmitter with sensor facing down)
in an area with low vibrations and stable temperatures – near the possible
leak.
— A space of at least 15 cm (6") must be maintained above the transmitter for
installation of the measuring unit.
— A space of at least 10 cm (4") – preferably 30 cm (12") – must be maintained
below the docking station to permit access for maintenance.
Unpack the docking station.

66 ±4mm (2.6 ± 0.16") apart.
