INSTALLATION
There is no need to remove the meter from its case to com-
plete the installation, wiring, and setup of the meter.
Unpacking
Remove the meter from box. Inspect the packaging and con-
tents for damage. Report damages, if any, to the carrier.
If any part is missing or the meter malfunctions, please contact
your supplier or the factory for assistance.
Panel Mounting
•Prepare a standard 1/8 DIN panel cutout – 3.622" x 1.772" (92 mm
x 45 mm). Refer to Mounting Dimensions, page 28 for more details.
•Clearance: allow at least 4" (102 mm) behind the panel for wiring.
•Panel thickness: 0.04" - 0.25" (1.0 mm - 6.4 mm).
Recommended minimum panel thickness to maintain Type 4X
rating: 0.06" (1.5 mm) steel panel, 0.16" (4.1 mm) plastic panel.
•Remove the two mounting brackets provided with the meter (back-off
the two screws so that there is ¼" (6.4 mm) or less through the
bracket. Slide the bracket toward the front of the case and remove).
•Insert meter into the panel cutout.
•Install mounting brackets and tighten the screws against the panel.
To achieve a proper seal, tighten the mounting bracket screws
evenly until meter is snug to the panel along its short side. DO NOT
OVER TIGHTEN, as the rear of the panel may be damaged.

Connections
All connections are made to removable screw terminal connectors
located at the rear of the meter.
Use copper wire with 60°C or 60/75°C insulation
for all line voltage connections. Observe all safety
regulations. Electrical wiring should be performed
in accordance with all applicable national, state,
and local codes to prevent damage to the meter
and ensure personnel safety.
Connector Labeling
The connectors label, affixed to the meter, shows the location of the
connectors. It also identifies the location of the RTD/TC selector switch.
Figure 2. Connector Labeling
Power Connections
Power connections are made to a two-terminal connector labeled
POWER on Figure 2. The meter will operate regardless of DC polarity
connection. The + and - symbols are only a suggested wiring convention.

Signal Connections
Signal connections are made to a five-terminal connector labeled
SIGNAL on Figure 2. The COM (common) terminal is the return for all
types of input signals.
Thermocouple and RTD Connections
The following figures show examples for thermocouple and RTD con-
nections.
The RTD/TC selector switch must be set to the proper position for the
meter to accept the selected temperature input.
The input type is selected using the Setup menu.
The selected thermocouple input must correspond to thermocouple sen-
sor and wire type used.

SETUP AND PROGRAMMING
•There is no need to recalibrate the meter
when first received from the factory.
•The meter is factory calibrated prior to ship-
ment, for all input types, in degrees Fahren-
heit. The calibration equipment is certified to
NIST standards.
Overview
There are no jumpers involved in the setup process of the meter. The
RTD/TC selector switch, located between the SIGNAL and RJ11 con-
nectors, must be set accordingly for the meter to accept RTD or thermo-
couple inputs, Figure 2.
Setup and programming is done through the front panel buttons.
After power and signal connections have been completed and verified,
apply power to the meter.

Setting the Input Signal (inpt)
Enter the Input menu to set up the meter to display thermocouple (tC)
or RTD (rtd) inputs.
If RTD is selected, the display shows A385 or A392. Select the coeffi-
cient to match the RTD sensor, either 0.00385 (European curve) or
0.00392 (American curve).
