3.1.1 Electrical connection for control and changeover unit
The connections (screwless spring-type terminals) for the control systems are located in the control panel bottom
part. Connection diagrams for the control are enclosed and for the changeover unit, see section 4.9.
To enter the control panel bottom part, the control panel top part must be folded up. To do this, loosen the front screw
on the control panel (Fig. 70) and fold up the control panel top part until it snaps into the lock at the side – Fig. 71.
Information!
Be sure to note the separate wiring of the extra-low voltage line (sensor) and low-voltage line
(230 VAC)! – Fig. 73.
The connection to the terminal blocks (screwless spring-type terminals) should be made using fine-wire PVC
sheathed cables and the cables are not allowed to be too short or under tension in the cable ducts. This is to allow
the control panel to be folded open even when the cables are connected – Fig. 72, 73.
To close the control panel top part again, loosen the side lock and fix again with screw at front.
