Mechanical installation
The Model 310 may be surface mounted onto a panel,
attached to DIN rails using adapter clips or wall mounted using two optional enclosures.
Location
Although the Model 310 is encapsulated, all wiring
connections are made to exposed terminals. The unit
should be protected from weather and moisture in
accordance with electrical codes and standard trade
practices.
In any mounting arrangement, the primary concerns
are ease of wiring and attachment of the programming
cable.
The unit generates very little heat so no consideration
need be given to cooling or ventilation.

Enclosure Dimensions
Surface Mount Installation
The Model 310 may be mounted to the surface of any
panel using double sided adhesive tape or by attaching
fasteners through the holes in the mounting anges of
the unit.
DIN Rail Mounting
Optional clips snap onto the mounting anges allowing
the Model 310 to be attached to DIN 15, 32, 35 mm DIN
rail systems.
Wall Mounting
Optional metal and plastic enclosures are available to
mount the Model 310 to a wall when no other enclosure
is used. The enclosure is rst attached to the wall using
fasteners through its mounting holes.
After wiring, the transmitter may be attached to the
enclosure with the terminal headers facing in using the
slots in the mounting anges. As an alternate mounting arrangement, the Model 310 may be fastened to the
box cover using double-sided adhesive tape.
Model 310 Electrical Installation
strips have removable plug-in connectors to make wiring easier.
1. Refer to Figure 3 for
terminal connections.
2. As shown in gure 4,
connect loop power supply
positive (+) to Model 310
terminal marked 4-20mA
loop (+).

Locations
3. Connect terminal
marked 4-20mA loop (-) of Model 310 to positive (+)
analog terminal of input device (Chart Recorder, PLC,
etc.).
4. Connect negative (-) analog terminal of input device
to loop power supply negative (-).
5. If Wiring a Series 200
sensor, connect the red
wire (signal) to Signal (+)
terminal, black wire (common) to Signal (-) terminal
and the shield to Shield
Ground terminal (Disregard
shield for the IR sensors).
If Wiring a Series 4000 sen-

sor, connect the clear wire
(signal) to Signal (+) terminal, black wire (common) to
Signal (-) terminal, shield wire to Shield Ground termi-
nal, and red wire (power) to Power (4000 only) terminal.
If wiring to a sine wave output sensor consult factory.
6. For maximum EMI Protection, connect Model 310
ground lug to panel ground. See Note #1
7. Ensure that all connections are tight, then plug connector into header.
Note #1:
Included with every Model 310 is a 310IK kit containing a screw, lock washer and ground lead to connect
the Model 310 to Earth Ground. This will help prevent
electrical interference from affecting the Model 310’s
normal operation.
Per standard wiring practices, the loop power must be
off before making any wire connections. The terminal
