8.2.3 Mounting the electronic modules
Please observe:
1 The correct base module must have been previously mounted.
2 Electronic modules are fitted onto the previously mounted and, where applicable, wired base
modules.
Method:
1 Press the electronic module squarely onto the base module.
2 Tighten the two screws on the top of the electronic module.
8.2.4 Prevention of false mounting
A mechanical coding element prevents an electronic module from being mounted onto the wrong
base module – for example, following a defect in an electronic module. The coding element consists of
two pieces and is supplied with every electronic module.
The complete coding element is mounted on the underside of each electronic module. When
mounting the electronic module for the first time, the lower part of the coding element is automatically
inserted into the recess provided in the base module.
Note
Before plugging the electronic modules, it is advisable to blowclean the station with
compressed air. This prevents dust and grains of dirt from contaminating the contacts, which
can negatively influence the communication on the station.
Attention
To guarantee the protection class IP67, the screws at the base modules have to be firmly
tightened.
Furthermore the seal at the lower side of the electronic module housing must not be
damaged or slipped due to wrong transport, storage or similar.
Note
When plugging electronic modules for the first time, an initial resistance must be overcome.
This is because the lower part of the coding element has to be pressed into the base module.
