All connection terminals are detachable plug-in terminals.
To avoid incorrect wiring, terminals which can be connected to AC 230 V (supply and
relay outputs) are physically separate from the other terminals.
Cable restraints must be used for the wires to termi-
nals 19 ... 28 (AC 230 V). The conductors must be
secured with cable ties (see diagram).
Ensure that the power is off before inserting or removing plug-in terminals
connected to a mains voltage.
The RXC20, RXC21 and RXC22 room controllers communicate with other devices via
the following interfaces:
 L
W ® bus (terminals CLA and CLB) for communication with:
ON ORKS
 PXX-Lxx, PXR system controller or NIDES.RX interface (to Desigo)
 Other Desigo RXC devices
 L

 PPS2 (terminals CP– and CP+):
 Interface to the QAX... room units. (In addition to PPS2, the L
also looped to the tool socket on the room unit.)
 Tool socket (RJ45) on the room controller or room unit, for:
 RXT10 commissioning and service tool (L
