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.
3. Open clamps with a fitting screwdriver and connect electrical sys-
tem to the controller.
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)
With the help of an external relay (art. no. 77502), a 0-10V/PWM output
V(X) (V1, V2) can be used to obtain a switching capacity of 230 VAC (I)
or a potential-free change-over contact (II). The external relay is then
activated via the signal output (0V = "off" (0 VAC or open or closed), 10V
= "on" (230VAC or closed or open).
1. Connect external 0-10V relay to signal output, e.g. V1.
2. Assign additional function to signal V1. See " Relay functions " on
page 43
3. Disable the speed control for the corresponding 0-10V / PWM output
(Off). See " Variant " on page 42
Electrical Terminals
For high-efficiency pumps with 0-10V / PWM signal input, the power can be provided (V1 /V2 parallel operation) over a free
relay.
The connection of the ground wire is made at the lower gray terminal block. The neutral conductor N is connected to terminal
block N. The PE protective conductor must be connected to the PE metal terminal block!
