3. Drill holes in the wall at the locations marked in
Step 2 and insert wall anchors (if necessary).
4. Position the IOM controller and insert the screws
through the holes in the mounting clips, and
carefully tighten all the screws.
IMPORTANT: Do not overtighten the mounting
screws. Overtightening the screws may damage the
mounting clips or IOM housing.

DIN Rail Mount Applications

To mount the IOM controller on a DIN rail:
1. Securely mount the section of DIN rail horizontally
and centered in the required space.
2. Carefully pull down (outward) the bottom mounting
clips until they lock in place (Figure 4).
Note: The top mounting clip is not used on DIN
rail applications. You may remove the clip.
3. Hang the IOM controller on the DIN rails using the
DIN rail hooks on the back of the IOM controller.
4. Secure the IOM controller on the DIN rail by
pressing the bottom mounting clips up until they
snap into place.

Wiring
IMPORTANT: Do not connect 24 VAC supply
power to the IOM controller before finishing wiring
and checking all wiring connections. Short circuits or
improperly connected wires may result in permanent
damage to the equipment.
IMPORTANT: Use copper conductors only. Make
all wiring in accordance with local, national, and
regional regulations. The IOM controller is a
low-voltage (<30 VAC) device. Do not exceed the
IOM controller electrical ratings.
IMPORTANT: Prevent any static electric discharge
to the IOM controller. Static electric discharge can
damage the IOM controller and void any warranties.
Refer to the MS/TP Communications Bus Technical
Bulletin (LIT-12011034) for more information on
Master-Slave/Token-Passing (MS/TP) devices.
To wire the IOM controller:
1. Terminate wiring per engineering drawings.
2. If the IOM is connected to the FC Bus of a Network
Automation Engine (NAE) or Network Control
Engine (NCE), wire the FC Bus in a daisy chain.
