Electrical connection
Connecting the controller
Wall mounting
To connect the wiring, pull the controller out of its base. To connect the feeding cables, break
through the holes in the marked locations at the top or bottom at the base housing and fit
supplied grommets or suitable cable glands. Ensure that the cables are not subject to torsion
or bending by taking suitable precautions before inserting the cable.
The controller is connected as illustrated in the following wiring diagrams.
Open the housing to connect the cables. To connect the feeding cables, make holes in the
marked locations at the top, bottom or back of the base of the housing and fit suitable grom-
mets or cable glands.
Connecting sensors
Cables with a minimum cross-section of 2 x 0.5 mm² can be connected to the terminals at
the base of the housing.
Connecting actuators
− 0 to 10 V control output: Use cables with a minimum cross-section of 2 x 0.5 mm².
− Three-step or on/off outputs: Connect cables with at least 1.5 mm² suitable for damp lo-
cations to the terminals of the controller output. The direction of travel needs to be
checked at start-up.
Connecting pumps
Connect all cables with at least 1.5 mm² to the terminals of the controller as illustrated in the
wiring diagram.
NOTICE
The electric actuators are not automatically supplied with a voltage by the controller.
They can be connected over terminals 25 and 28 to an external voltage source. If this
is not the case, connect a jumper from terminal 18 to terminals 25 and 28.
