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.
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.
Do not use tools of any kind (screwdrivers, pens, pencils, etc.) to
operate the keypad of the unit.
