Terminal covers (RXZ30.1) are available as an option, to protect the connection
terminals from physical contact and dirt. The service LED remains visible when the
terminal covers are in place, and the programming button can be operated with a
pointed implement. The cable is connected to the room controller by breaking out
the perforated cable entry guide.

All connection terminals are detachable plug-in screw-terminals.
To avoid incorrect wiring, terminals which can be connected to AC 230 V (relay
outputs) are physically separated from the other terminals.
The cable restraints on the housing base must be used
for the connections to terminals 19 ... 27 (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.
