Wall Installation
1. Unscrew cover screw completely.
2. Carefully pull upper part of housing from lower part.
During the removal, the brackets are released as
well.
3. Set upper part of housing aside. Do not touch the
electronics.
4. Hold the lower part of the housing in the selected
position and mark the 3 mounting holes. Make sure
that the wall surface is as even as possible so that
the housing does not become distorted when
screwed on.
5. Using a drill and size 6 bit, drill three holes at the
points marked on the wall and push in the plugs.
6. Insert the upper screw and screw it in lightly.
7. Fit the upper part of the housing and insert the
other two screws.
8. Align the housing and tighten the three screws.
1. Open the terminal cover.
2. Strip lines a max. of 55 mm, assemble the strain
reliefs, strip wire ends 8-9 mm (Figure 1)
3. Open the terminals with a fitting screwdriver (figure
2) and connect the electrical system to the con-
troller.
4. Clip on the terminal cover again and close it with
the screw.
5. Turn on mains supply and put the controller into
operation.

Additional Information
External relay at signal output V(X) (0-10V / PWM)
Using an external relay (art. no. 77502), a 0-10V/PWM output V(X)
(V1, V2) can be used to get a switching power of 230 VAC (I) or a
potential-free changeover contact (II). The external relay is activated
via the signal output (0V = "off" (0 VAC or opened or closed), 10V =
"on" (230 VAC or closed or opened).
1. Connect external 0-10V relay to signal output, e.g. V1.
2. Assign additional function to signal V1. See " Relay functions " on
page 41
3. Disable the speed control for the corresponding 0-10V / PWM out-
put (Off). See " Variant " on page 40
