Siemens RXC41 – Extension module for the control of blinds CA2N3843en_06
Building Technologies 2015-12-14
Cable sizing for motorized blinds depends on the connected load and the local
installation regulations. Neutral and protective conductors are looped on the controller
so that there is no need for external terminals. The cables must be secured with cable
restraints.
An interlock makes outputs Q14 / Q 24 and Q34 / Q44 mutually exclusive. To protect
the cables, the circuits must be fused in accordance with local regulations.
RXC41.1: The volt-free relay outputs are protected by an integral fine-wire fuse
with a nominal current of 3.15 A. The maximum load per module (for both motors
together) is therefore restricted to 3A.
RXC41.5: No internal fusing. The sizing and fusing of the power lines are oriented
to overall connected load and local regulations. The switching circuits must be
externally fused (≤10 A).
Mounting
The RXC41 extension module is mounted together with the RXC30 / RXC31 / RXC38
basic module and any additional extension modules on a DIN rail (type EN50022-
35x7.5).

When mounting, note the following:
• The controller should not be freely accessible after mounting
• Ensure adequate air circulation to dissipate heat generated during operation.
• Easy access is required for service personnel
• Local installation regulations must be observed.
The mounting instructions are printed on the controller packaging.
Commissioning
The notes in the technical documentation for the RXC30 / RXC31 / RXC38 room
controller (data sheet 3840, 3844) apply equally to a combination comprising the
RXC30 / RXC31 and the RXC41 extension module.
• The module is not protected against accidental connection to AC 230 V on the
SELV / PELV side.
• Mains AC 230 V for the relays must be disconnected before plugging and
unplugging the terminal blocks (danger of electric shock!)
