Din Rail Mount Applications - Johnson Controls MS-IOM1710-0 Installation Instructions Manual

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
clip(s) until they lock in place (Figure 2).
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.
To remove the IOM controller from the DIN rail, snap
the bottom DIN clips to the outboard position and
carefully lift the IOM controller off the DIN rail.

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: User 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
(Figure 5).

3. If the IOM is connected to the SA Bus of an NCE or
FEC, wire the SA Bus in a daisy chain (Figure 6).

Note: The SA/FC Bus Port (RJ-12, 6-pin, modular
connector) provides 15 VDC on two of its pins,
which is used to power the MS-BTCVT (Figure 7).
Note: If the IOM controller is at one end of the SA
Bus daisy chain, set the End-of-Line (EOL) switch
to ON.
4. Connect power to the IOM controller.
5. Download and commission the IOM controller. See
the Commissioning section.
