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

draino.

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

screwedinhandtight.Exceedingthemax.torquespeciedinchapter

"Technical data" can damage the wall mounting plate.

Tip:

With plastic housing, the cable gland can be mounted in three posi­tions each displaced by 90°. Simply exchange the cable gland against

theblindpluginthettingthreadedhole.

Note:

Depending on the delivery date of the sensor, the connection cable

maybeequippedwiththreeorfourwires.Takenoteofthedierent

assignments of the terminals in the housing base in "Wiring plan".

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.
