9. Connect the power cable to the terminals.

10. Remount the back panel.

4.4 RS485/RS422 interface

Units in the SpaceSaver and SpaceSaver PLUS versions are equipped with a four-pin RS485 interface as standard. The interface can be reduced to a two-pin RS422 interface.

1.Bridge the terminals to reduce the interface to a two-pole RS422 interface.

-X3/1 to X3/3

-X3/2 to X3/4

2.Use twisted wires (e. g. LiYY (TP) 2x2x0.5) for the connection.

3.Close the last unit with a 150 Ω terminating bus resistor.

4.5Connect performance optimization system (LOA)

Units in the SpaceSaver and SpaceSaver PLUS versions are equipped with a performance optimisation system (LOA) as standard.

With this system, 230 V signals are passed on to an external performance optimization system. By means of this signal, the system can interrupt the heating cycle and stop heating.

The LOA connection is compatible to systems from SICOTRONIC GmbH.
