Siemens RXC41 – Extension module for the control of blinds CA2N3843en_06
Building Technologies 2015-12-14
Cable restraints on the housing base must be
used for the connections to terminals 7 … 17
(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.
To protect the volt-free relay contacts and motors for control of the blinds, the module
incorporates a built-in replaceable fine-wire fuse (RXC41.1 only).

Replacing the fine-wire fuse (RXC41.1 only)
The RXC41 extension module communicates via a serial bus connection (the PE bus)
with the RXC30 / RXC31 / RXC38 controller. The PE bus connections are looped
through the module to the connection socket for the next extension module.
There is no direct connection to the L
ONWORKS® bus.
Disposal
The devices are classified as waste electronic equipment in terms of the European Direc-
tive 2012/19/EU (WEEE) and should not be disposed of as unsorted municipal waste.
The relevant national legal rules are to be adhered to.
Regarding disposal, use the systems setup for collecting electronic waste.
Observe all local and applicable laws.
Engineering notes
The RXC41 can be used only in conjunction with an RXC30 / RXC31 / RXC38 basic
module (and possible additional extension modules). The plug-in connection between
the basic module and the extension modules incorporates both the communications
and the power supply. The power supply is limited to a maximum of two extension
modules.
The cables for signal inputs D1 … D4 (SELV / PELV) must be routed separately from
the AC230 V cables and must comply with SELV / PELV requirements. The low voltage
and mains voltage must not be routed in the same cable.
Only volt-free pulsed momentary-contact switches may be connected to the
signal inputs.
