Installation
The PAX Lite 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.

peak max.
Input B
: Logic level signals only
Trigger levels: V
IL
= 1.0 V max; V
IH
= 2.4 V min; V
MAX
= 28 VDC
