Fig. 5: Hole pattern - wall mounting plate (external housing)
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 hous-
ing 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 posi-
tions each displaced by 90°. Simply exchange the cable gland against
theblindpluginthettingthreadedhole.
4. Connect the wire ends as described in chapter "Connection plan".
Take note of the numbering.
5. Connect the screen to the internal ground terminal, connect the
external ground terminal to potential equalisation
1) 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.
