Installing MP-C on a DIN Rail
You install MP-C on a DIN rail inside a cabinet to ensure that the device is securely fastened and to allow for sufficient ventilation.
The MP-C 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.
Installation orientation restrictions
The restrictions on installing the device in various orientations differ between the different MP-C controller models ( Pour plus d'informations, voir MP-C Models .). In this regard, the MP-C models can be divided in the following categories:
MP-C models without “-M” in the product name:
MP-C-15A, MP-C-18A, MP-C-18B, MP-C-24A, and MP-C-36A
MP-C models with “-M” in the product name:
MP-C-24A-M and MP-C-36A-M
Under normal operating conditions of 0 to 50 °C (32 to 122 °F), the MP-C controller models MP-C-15A, MP-C-18A, MP-C-18B, MP-C-24A, and MP-C-36A 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.
Installing the MP-C rotated 180 degrees from the horizontal position with device label text up and down (“e” in the figure), face down from a ceiling (“d” in the figure), or face up on a horizontal surface (“f” in the figure) is not supported.
When the MP-C is used for rooftop applications, -40 to +60 °C (-40 to +140 °F), the device should be installed horizontally, with the device label text in the upright position reading left to right. See “a” in the following figure. Any other installation orientation (“b”, “c”, “d”, “e”, and “f” in the figure) may exceed the controller's thermal specifications, which can damage the controller.
Under normal operating conditions of 0 to 50 °C (32 to 122 °F), the MP-C controller models MP-C-24A-M and MP-C-36A-M 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.
Up and down, which means that the device is rotated 180 degrees from the horizontal position and with the device label text up and down. See “e” in the following figure.
Face up on a horizontal surface. See “f” in the following figure.
Installation on a DIN rail
A DIN rail is a common and convenient technique for installing the MP-C 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 MP-C rail and adjacent rails or other devices.
The MP-C 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.
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.
Installation in a cabinet
All MP-C controller models are recommended to be installed in a cabinet, unless local regulations allow an exception.
The device should be installed within an enclosure such as a control cabinet for isolation to exposed live parts.
The MP-C controller can be installed in a standard DIN enclosure/cabinet.
When installing MP-C controllers in a cabinet, it is recommended to provide ample space between the DIN rails and controllers for sufficient ventilation.
Screw terminals
Most of the MP-C controller models have removable screw terminal blocks for the power input and onboard I/O. The screw terminal blocks are easy to install and remove from the device. You can replace the controller in seconds because no terminal wiring is affected. The terminal blocks are installed on the device at delivery. Spare terminal blocks can be ordered separately using the part number SXWMPCCON10001.
For high-power relay outputs, a two-position fixed terminal block is used. The high-power relay output is only available on the MP-C-15A and MP-C-18A models. Pour plus d'informations, voir MP-C Onboard I/O .
The MP-C controller models with “-M” in the product name, MP-C-24A-M and MP-C-36A-M, have fixed screw terminals for the power input and onboard I/O and a removable screw terminal block for connection to the BACnet MS/TP (RS-485) network.
MP-C Display
All MP-C controller models, except MP-C-24A-M and MP-C-36A-M, can be equipped with MP-C Display (part number SXWMPCDSP10001), which is an add-on module that enables manual override control of analog and digital outputs. The module consists of an LCD display and keys. The module is designed for permanent installation.
Do not try to remove the MP-C Display module as it may damage the enclosure and the module. Once installed, the MP-C Display module cannot be removed.
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 clamp below the device.
