The IP-IO module device 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 IP-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 IP-IO module rail and adjacent rails or other panel-mounted devices.

The IP-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.

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 IP-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.

Installing the IP-IO module 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 IP-IO module 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 IP-IO module's thermal specifications, which can damage the module.

The IP-IO module can be installed in a standard DIN enclosure.

When installing IP-IO modules in a 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.

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.

The IP-IO module is delivered with terminal blocks installed on the device.

The terminal blocks are removable. You can replace an IP-IO module in seconds because no terminal wiring is affected. The only exception is the high power relay output on the IP-IO-UIO5DOFA4 model, which uses a two-position fixed terminal block due to current requirements.

All IP-IO module 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.

Danger Danger

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

De-energize the high-voltage equipment connected to the relay outputs before wiring. More than one disconnect switch may be required to de-energize the equipment.

Failure to follow these instructions will result in death or serious injury.

Caution Caution

RISK OF ELECTRIC SHOCK

Disconnect the 24 VAC/DC power supply and other electrically powered equipment before wiring.

Failure to follow these instructions can result in injury or equipment damage.

Notice

EQUIPMENT DAMAGE

Always use the recommended cables (or wires with larger cross-sectional area). For more information, see Wiring .

Failure to follow these instructions can result in equipment damage.

To wire a terminal block on an IP-IO module

  1. De-energize the high-voltage equipment connected to the relay outputs of the IP-IO module.

    This only applies to the IP-IO-UIO5DOFA4 model, which has relay outputs.

  2. Disconnect the 24 VAC/DC power supply and other electrically powered equipment that is connected to the IP-IO module.

  3. Ensure that the correct terminal block is used and that it is properly installed on the IP-IO module. For more information, see Installing a Terminal Block on an IP-IO Module .

  4. Loosen the screws of the terminal block.

  5. Strip approximately 7 mm (0.3 inch) of the insulation from the end of each wire.

  6. Insert the stripped end of each wire fully into its intended terminal. Ensure that no bare wire strands extend from the terminal.

  7. Tighten the screws using a small flat-blade screwdriver. Ensure that the screws are fully tightened. Use the following recommended screw tightening torque: 0.56 Nm (5 lbf.in).
