Installation
The PAX2S 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.
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 operating
temperature and provides good air circulation. Placing the unit near devices that
generate excessive heat should be avoided.
The bezel should only be cleaned 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.
Do not use tools of any kind (screwdrivers, pens, pencils, etc.) to operate the
keypad of the unit.

Bridge Excitation
This jumper is used to select bridge excitation voltage level. Use the 5 V
excitation with high output (3 mV/V) bridges, so that the higher sensitivity 24
mV range can be used. Using the 5 V excitation also reduces bridge power
consumption compared to the 10 V excitation. A maximum of four 350 ohm
load cells can be driven by the internal bridge excitation voltage.
