8.1

Heating

We recommend the installation of a heating
resistor  to  prevent condensate from forming
underneath the cover, for instance, in appli-
cations with strongly fluctuating ambient tem-
peratures, high humidity and in outdoor ap-
plications.
The  heating  resistor  "R"  is  controlled  via  a
thermostatic  switch  "TW"  (bimetallic-element
switch).  A  continuous-operation  voltage  is  re-
quired for operation (indicate when ordering).
The  switch-off  temperature  is approximately
+60

°

C, the re-start tempe40

°

C.

For power supply, connect the heating resistor
with thermostatic switch to clamps 7 and 8.

8.1.1 Retrofitting the heating resistor

You can install and connect a heating resistor
at a later date.
– Remove cover

– Secure heating resistor to the position in-

tended for this purpose (see Fig. 22) using
the two self-cutting screws supplied with the
resistor.

– Secure temperature monitor in the respec-

tive bore hole of the mounting bracket (nut
width across flats 7).

– Connect the flexible lead end of the tem-

perature monitor and the heating resistor to
clamps 7 and 8.

– Route and mount lines in the actuator such

that they are protected from moving or ro-
tating parts and are not damaged when the
cover is removed or replaced.
