The potential-free contacts of external moni t or ing devic-
es (e.g. ventilation interlock, safety high limit humidistat,
airow monitor, etc.) are connected in series (external
safety chain "K2") to the terminals "SC1" and "SC2" on
the driver board in accordance with the wiring diagram.
The connecting cable must be led through a cable gland
or grommet into the control compartment.
Caution! A high limit humidistat is highly recomen-
ded to prevent risk of over-humidication and potential
damage to property.
Note: If, for whatever reason, no external monitoring
devices are connected, a cable bridge "J3" must be
installed on the contacts "SC1" and "SC2" of the ter-
minal block.
CAUTION! Do not apply any extraneous voltage to
contacts "SC1" and "SC2" via the contacts of the
external monitoring devices.

Control compartment
The signal cable of an external controller or of a humidity
sensor (if the internal P/PI controller is used) is to be
connected according to the wiring diagram to the ter-
minals "IN" and GND" on the driver board in the control
compartment. The admissible signal values can be found
in the technical data table in the operation manual. The
connecting cable must be led through a cable gland or
grommet into the control compartment.
Note: if the external controller or the humidity sensor
shall be supplied with 10 V or 24 V from the driver board
(terminal “A+”), the jumper JP1 must be set to 10V or
24V accordingly.
Note: The admissible humidity control signal values
can be found in the technical data table in the operation
manual.
If a shielded signal cable is used, connect the cable
shield to terminal "GND".
Caution! If the signal cable shield is already connected
to a po ten tial or a grounded conductor, do not con-
nect it to terminal "GND".
