Installation
The PAX meets NEMA 4X/IP65 requirements when properly installed. The
unit is intended to be mounted into an enclosed panel. Prepare the panel cutout
to the dimensions shown. Remove the panel latch from the unit. Slide the panel
gasket over the rear of the unit to the back of the bezel. The unit should be
installed fully assembled. Insert the unit into the panel cutout.
PANEL
BEZEL
While holding the unit in place, push the panel latch over the rear of the unit
so that the tabs of the panel latch engage in the slots on the case. The panel latch
should be engaged in the farthest forward slot possible. To achieve a proper seal,
tighten the latch screws evenly until the unit is snug in the panel (Torque to
approximately 7 in-lbs [79N-cm]). Do not over-tighten the screws.
Installation Environment
The unit should be installed in a location that does not exceed the maximum
operating temperature and provides good air circulation. Placing the unit near
devices that generate excessive heat should be avoided.
The bezel should be cleaned only with a soft cloth and neutral soap product.
Do NOT use solvents. Continuous exposure to direct sunlight may accelerate the
aging process of the bezel.

POWER WIRING
Primary AC power is connected to Terminals 1 and 2. To reduce the chance of
noise spikes entering the AC line and affecting the indicator, the AC power should
be relatively “clean” and within the specified limits. Drawing power from heavily
loaded circuits or circuits that also power loads that cycle on and off (contactors,
relays, motors, machinery, etc.) should be avoided.
AC Power
PROGRAM DISABLE INPUT WIRING
PGM.DIS. (Terminal 3) is a digital input that is active when connected to RTD-
(Terminal 6). Any form of mechanical switch or current sinking logic with less
than 0.7 V saturation may be used. The use of shielded cable is recommended.
Follow the EMC Installation Guidelines for shield connection.

SIGNAL WIRING (RTD SENSOR)
RTD sensors are used in applications where a high degree of accuracy is
required. Most RTD sensors available are the 3-wire type. The 3rd additional
wire is a sense lead for canceling the effects of lead resistance at the probe. The
sense lead connects to Terminal 5 (RTD+), the common lead to Terminal 6
(RTD-), and the excitation lead to Terminal 4 (+ Excitation). The excitation and
sense leads are generally the same color because they are functionally the same
and may be interchanged at the meter. Four wire sensors have an additional
sense lead connected (at the probe) to the common lead. Leave the extra sense
lead disconnected when using a four wire probe with the PAXLRT meter.
Always refer to the sensor manufacturer ’s instructions for probe wiring
connections, if available. Two wire RTD sensors may be used with the PAXLRT
by shorting Terminal 4 to Terminal 5, if the distance between sensor and meter
is less than 30 feet. The total lead resistance can be used to predict the
temperature error for 2-wire sensors, according to 2.5°C/ ?? of lead resistance.
Note: Extended cable runs can be made provided the lead resistance is less
than 20 ? /lead and the resistance is equal in each lead.
WIRING OVERVIEW
Electrical connections are made via screw-clamp terminals located on the
back of the meter. All conductors should conform to the meter ’s voltage and
current ratings. All cabling should conform to appropriate standards of good
installation, local codes and regulations. It is recommended that the power
supplied to the meter be protected by a fuse or circuit breaker.
When wiring the meter, compare the numbers embossed on the back of the
meter case against those shown in wiring drawings for proper wire position. Strip
the wire, leaving approximately 0.3" (7.5 mm) bare lead exposed (stranded wires
should be tinned with solder). Insert the lead under the correct screw-clamp
terminal and tighten until the wire is secure. (Pull wire to verify tightness.)
