Installing MP-C on a Flat Surface

You install MP-C on a flat surface 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.

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.

The restrictions on installing the device in other orientations differ depending on the operating conditions.

Notice

CONTROLLER DEVICE DAMAGE

Follow the installation orientation restrictions that apply to the specific SmartX IP Controller device.

Failure to follow these instructions can result in equipment damage.

Under normal operating conditions of 0 to 50 °C (32 to 122 °F), the MP-C 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.

The MP-C can be installed in a standard DIN enclosure.

When installing MP-Cs in a cabinet, it is recommended to provide ample space between the DIN rails and controllers 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.

Notice

CONTROLLER DEVICE DAMAGE

Use an end clip (part number SXWDINEND10001) when you install the SmartX IP Controller device on a vertical DIN rail.

Failure to follow these instructions can result in equipment damage.

The MP-C is delivered with terminal blocks installed on the device. Spare terminal blocks can be ordered separately using the part number SXWMPCCON10001.

The terminal blocks are removable. You can replace an MP-C in seconds because no terminal wiring is affected. The only exception is the high power relay outputs on the MP-C-15A and MP-C-18A models, which use a two-position fixed terminal block due to current requirements.

All MP-C models 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.

Notice

CONTROLLER DEVICE DAMAGE

Do not try to remove the MP-C Display module.

Failure to follow these instructions can result in equipment damage.

To install MP-C on a flat surface

  1. Refer to the dimensional drawing before installing the MP-C.

     
    action_zoom_plus_stroke

  2. Ensure that you have the proper mounting hardware and anchoring system.

  3. Check the weight-bearing load before choosing your mounting hardware.

  4. Find a suitable location and surface on which to mount the MP-C.

  5. Drill three mounting holes that fit number 8 or M4 screws (or anchors):

    • Two holes for the top two screws on which you hang the MP-C

    • One hole for the screw at the bottom that prevents the device from being lifted off the top two screws

    Use the following drawing to measure out the location of the three holes for MP-C-15A, MP-18A, and MP-C-18B.

    Use the following drawing for MP-C-24A and MP-C-36A.

     
    action_zoom_plus_stroke
    Note:

    You can also use the 1:1 drill template in the installation sheet that comes with each controller.

  6. Install number 8 or M4 (4 mm) pan head self-tapping screws (or anchors) in the two top holes, leaving approximately 5 mm (0.2 inch) space between the head of the screw (or anchor) and the flat surface to accommodate the MP-C material thickness.

  7. Fit the two keyhole slots on the back of the MP-C enclosure to the heads of the mounted screws (or anchors) and then slide the MP-C down in place on the screws (or anchors).

     
    action_zoom_plus_stroke

  8. Fit the bottom screw (or anchor) to the hole at the bottom of the MP-C and tighten the screw (or anchor).
