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
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.

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.

The meter has an input jumper and switches, which must be checked and/or
changed prior to applying power. To access the input jumper and switches,
remove the meter base from the case by firmly squeezing and pulling back on
the side rear finger tabs. This should lower the latch below the case slot (which
is located just in front of the finger tabs). It is recommended to release the latch
on one side, then start the other side latch.
Set-Up DIP Switches
A DIP switch is located inside the meter. It is used for the selection of decimal
points, backlight annunciator, and scaling. Selecting the “ON” position enables
the function.

Input Range Jumper
A jumper is used for selection of the voltage or current input range. Select the
proper input range that will be high enough to avoid input signal overload. It is
important that only one jumper position is used at a time. Avoid placing a jumper
across two different input ranges.
