13.2.6 Mounting of BL67 directly on the mounting plate
The BL67 stations can be mounted directly onto a pre-drilled galvanized mounting plate. The mounting
plate has to be connected to protective earth (PE).
Fasten the station on the mounting plate by screws t
hrough the holes in the base modules and in
the gateway.
13.2.7 FE connection
The station is connected to functional earth by the FE connection at the upper right drilling of the
gateway
NOTE
Mounting the BL67-stations on a mounting rail
The mounting rails used for BL67 should be mounted
onto a galvanized mounting plate with a mini-
mum thickness of 2 mm/0.08 inch. This a
llows a reference potential for protective earth (PE) and func-
tional earth (FE) to be created.
Please allow for a maximum distance of 150 mm/5.91 inch between mounting holes, when mounting
no
n pre-drilled mounting rails.
1 Insert
a screwdriver into the opening provided in the locking mechanism at the top of the gateway
and of the base modules and open the locking mechanism of all modules in the station.
2 Tilt the top of the station towards you, position the lower groove provided on the rear of the gate-
way and each base module onto the lower edge of the mounting rail.
3 Tilt the top of the base module away from you and towards the mounting rail and close the locking
mechanism at the gateway and every base module.
4 The station is mounted on the mounting rail.
13.2.8 Mounting end brackets
BL67 stations must be fixed securely onto the mounting rail using two end brackets.
Method:
Clip the end bracket onto the mounting rail.
If necessary, loosen the screw beforehand.
Slide one end bracket up to the gateway and one up
to the last module in the station and tighten
the screws.
If the mounting plate is not connected to ground, the station has to be grounded via a sepa-
rate ground terminal at the FE contact of the gateway.
