Mounting the electronics
module
To dismount the electronics module from the new housing, proceed
as follows:
1. Insert the electronics module carefully into the new housing.
Information:
The electronics module is connected via a plug. Make sure that the
plug is in the correct position. The marking notch must be in position
"18.00 h".

Tip:
Mount the wall mounting plate in such a way that the cable gland of
the base points downward. Rain and condensation water can thus
draino.
The base of stainless steel can be displaced in 90° increments on the
wall mounting plate, the base of plastic by 180°.
Turn the cable gland of the electronics housing downward. The housing can be turned by 330° without the use of any tools.
Warning:
With the plastic housing, the four screws of the base may only be
screwedinhandtight.Exceedingthemax.torquespeciedinchapter
"Technical data" can damage the wall mounting plate.

The connection cable comes pre-assembled. If necessary, shorten it to the
requested length, cut the breather capillaries clean. Remove approx. 5 cm of
the cable mantle, strip approx. 1 cm insulation from the ends of the individual
wires. After shortening the cable, fasten the type plate with support back on
the cable.
