Installing the transmitter
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 in-
stallation of the measuring unit.
— A space of at least 10 cm (4") – preferably 30 cm (12") – must be maintained be-
low the docking station to permit access for maintenance.
Unpack the docking station.
1 Remove raincover (protection against dust and splashing water).
2 Remove the 4-pole terminal block (Part No. 83 16 422), keep it in a safe place
and insert it again after completion of the installation work.
A drilling template is provided on page 64. The mounting holes are 66 ±4 mm
(2.6 ± 0.16") apart.
If the measuring unit is not to be mounted at this time:
Refit the raincover (protection against dust and splashing water).
CAUTION
Spacers (e.g. mounting bracket 68 09 951) must be used to prevent any twisting
of the housing when installed on uneven surfaces.
