Installing an RP-IO Module on a Flat Surface

You install an RP-IO module on a flat surface to properly fasten the device and to allow for sufficient ventilation.

The RP-IO 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.

Installation orientations

Under normal operating conditions of 0 to 50 °C (32 to 122 °F), the RP-IO module 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 RP-IO 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-IO rail and adjacent rails or other devices.

The RP-IO 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.

DIN rail end clip

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

EQUIPMENT DAMAGE

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

Failure to follow these instructions can result in equipment damage.

Installation in a cabinet

All RP-IO module models are recommended to be installed in a cabinet, unless local regulations allow an exception.

Important:

The device should be installed within an enclosure such as a control cabinet for isolation to exposed live parts.

When installing RP-IO modules in a cabinet, it is recommended to provide ample space between the DIN rails and modules for sufficient ventilation.

Screw terminals

The RP-IO modules have fixed screw terminals. For more information, see RP-IO Screw Terminals .

Anchor points for cable ties

The RP-IO modules have four anchor points that can be used to fasten cable ties or other accessories for bundling wires.

Optional covers

The RP-IO modules can be equipped with optional covers to reduce access to the screw terminals and wires if desired.

To install an RP-IO module on a flat surface

  1. Refer to the dimensional drawing before installing the RP-IO module.

     
    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 RP-IO module.

  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 RP-IO module

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

    Use the following drawing to measure out the location of the three holes for the RP-IO module.

    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 RP-IO module material thickness.

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

  8. Fit the bottom screw (or anchor) to the hole at the bottom of the RP-IO module and tighten the screw (or anchor).
