ANALOG INPUT MODULE
INSTALLATION
MOUNTING
The Analog Input Module must be properly installed in
a suitable enclosure that is rated for the location. The
enclosure must provide space to install and wire the
device and must also provide for ground wire
termination. Access into the enclosure must be gained
by using a special tool to open the enclosure. The
enclosure should be rated for the temperature range
of the location plus the temperature rise of all
equipment installed inside the enclosure. The
enclosure must be rated for electrical equipment that
is going to be installed.
NOTe
It is recommended to maintain a minimum of 4
inches clearance between the module and other
equipment to provide adequate room for wiring
and ventilation.
WIRING
All electrical connections are made to the field wiring
connectors furnished with the module. (Connectors
accept up to 12 AWG wire.) Refer to Figure 3-46 for
identification of module wiring terminals.

*Shields on power wires are optional unless required
by local codes.
Connect the module power supply to terminals 1 and
2. If additional terminals are required for powering
other devices, these devices should be connected to
terminals 4 and 5. Shields are to be connected to
terminals 3 and 6.
COM Connector — Terminals 1 to 6
LON Terminals
Be sure to observe polarity when wiring the LON.
1 — "A" side of signaling circuit for COM 1
2 — "B" side of signaling circuit for COM 1
4 — "A" side of signaling circuit for COM 2
5 — "B" side of signaling circuit for COM 2
3 & 6 — shield connections (shields required).
