2. Installation
2.1 Installing the controller
The controller is made up of the controller casing which contains the electronics components
and the rear casing section with the terminal blocks. To connect the controller, remove the screws
on the front panel and separate the controller housing from the rear casing.
For wall mounting, use four screws to mount the rear casing to a wall. The distances between the
holes are shown in Fig. 2.
For top hat rail mounting, mount the controller onto the top hat rail using the spring-mounted
hook on the rear casing.
For panel mounting, push the controller casing through the panel cut-out (92 x 138 mm) and in-
sert the fastening clips (delivered with the controller) into the notches at the top and bottom of
the casing. Then turn the threaded bolts in the direction of the control panel so that the casing is
pressed with its front frame against the control panel.
