Installing an RP Controller Expansion Module on a DIN Rail
You install an RP controller expansion module on a DIN rail to properly fasten the device and to allow for sufficient ventilation.
The RP controller expansion module can be installed on a DIN rail or other flat surface inside a cabinet. The device is recommended to be installed in a cabinet, unless local regulations allow an exception.
A DIN rail is a common and convenient technique for installing the RP controller expansion module along with other associated control and monitoring devices. The most efficient ventilation is achieved with the wall-mounted DIN rail oriented horizontally and with adequate space provided between the RP controller expansion module rail and adjacent rails or other devices.
The RP controller expansion module is typically installed horizontally (on a DIN rail going from left to right), with the device label text in the upright position reading left to right.
The restrictions on installing the device in other orientations, as well as the normal operating conditions, differ between different types of RP controller expansion modules.

Under normal operating conditions of 0 to 50 °C (32 to 122 °F), the light modules and high-voltage blind modules can be installed in the following orientations:
Horizontally (on a DIN rail going from left to right), with the device label text in the upright position reading left to right. See “a” in the following figure.
Vertically (on a DIN rail going from top to bottom), which means that the device is rotated +90 degrees or -90 degrees from the horizontal position. See “b” and “c” in the following figure.
Face down from a ceiling. See “d” in the following figure.
Rotated 180 degrees from the horizontal position with device label text up and down. See “e” in the following figure.
Face up on a horizontal surface. See “f” in the following figure.
Under normal operating conditions of 0 to 40 °C (32 to 104 °F), the low-voltage blind modules can be installed in the following orientations:
Horizontally (on a DIN rail going from left to right), with the device label text in the upright position reading left to right. See “a” in the following figure.
Vertically (on a DIN rail going from top to bottom), which means that the device is rotated +90 degrees or -90 degrees from the horizontal position. See “b” and “c” in the following figure.
Face down from a ceiling. See “d” in the following figure.
Rotated 180 degrees from the horizontal position with device label text up and down. See “e” in the following figure.
The only installation orientation that is not supported for the low-voltage blind modules is when the device is installed face up on a horizontal surface. See “f” in the following figure. In the face up position, the low-voltage blind module's thermal specifications may be exceeded, which can damage the module.
All RP controller expansion module models are recommended to be installed in a cabinet, unless local regulations allow an exception.
The RP controller expansion modules can be installed in a standard DIN enclosure/cabinet.
Local panel regulations should be followed when installing the RP controller expansion modules in a distribution panel.
When installing RP controller expansion modules in a DIN enclosure or cabinet, it is recommended to provide ample space between the DIN rails and modules for sufficient ventilation.
To help prevent the device from sliding down or sideways on the DIN rail, install an end clip for DIN 35 (part number SXWDINEND10001) tightly against the bottom or rightmost device on the rail. The end clip is easily removed if you bend the snap lock open with a screwdriver.
The RP controller expansion light, blind, and RP-C-EXT-REL-4 relay modules have connectors that allow the matching, external connectors (and cables) for the power supply, outputs, and digitals input to be plugged in on site quickly and easily. Pour plus d'informations, voir RP Controller Expansion Module Pluggable Connectors .
The RP controller expansion CRS-HH-REL-10 relay module has connectors for pluggable screw terminal blocks, which are delivered in a plastic bag with the device. The terminal blocks are easy to install and remove from the device. Pour plus d'informations, voir RP Controller Expansion Module Pluggable Connectors .
The RP controller expansion module has four anchor points that can be used to fasten cable ties or other accessories for bundling light weight wires.
It is recommended to always anchor excess cabling, in accordance with the local regulations, to alleviate all stresses on connectors and cable assemblies. When excess cabling is coiled and left suspended only from the module’s connectors, damage can occur to connectors and/or cable assemblies.
Push the DIN rail clip.

Hook the device onto the top of the DIN rail.
Push the device fully onto the DIN rail.
Release the DIN rail clip.
For a vertical DIN rail, install an end clip (stop) below the device.
