6.3.4 Fitting the conductor
1. Remove the insulation at a length of 0.34 - 0.39 in (9-10 mm).
2. Insert a screwdriver with a tip of maximum 0.015 x 0.1 in
(0.4 x 2.5 mm) into the square hole.
3. Insert the conductor into the corresponding round hole.
Remove the screwdriver. The conductor is now fixed in the
terminal.

6.3.5 Setting the analog inputs, terminals 53 and 54
The contacts A53 and A54 are positioned behind the control
panel and used for setting the signal type of the two analog
inputs.
The factory setting of the inputs is voltage signal "U".
Remove the control panel to set the contact. See fig. 27.

6.3.6 RS-485 GENIbus network connection
One or more CUE units can be connected to a control unit via
GENIbus. See the example in fig. 28.

If a 0/4-20 mA sensor is connected to terminal 54,
the input must be set to current signal "I".
Switch off the power supply before setting the
A54.
