INSTALLATION & CONNECTIONS
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.
Continuous exposure to direct sunlight may accelerate the aging process of
the bezel.
The bezel should be cleaned only with a soft cloth and neutral soap product.
Do not use solvents.
Do not use tools of any kind (screwdrivers, pens, pencils, etc.) to operate
the keypad of the unit.
STANDARD UNIT INSTALLATION
Prepare the panel cutout to the dimensions shown in Figure 1, Panel
Installation & Removal. Remove the panel latch and cardboard sleeve from
the unit and discard the cardboard sleeve. The unit should be installed with the
bezel assembly in place. Insert the unit into the panel cutout. While holding
the front of 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 slots possible. Tighten the screws
evenly until the unit is snug in the panel.
NEMA 4X/IP65 UNIT INSTALLATION
The optional NEMA 4X/IP65 PCU Controller provides a watertight seal in
panels with a minimum thickness of 1/8 inch. The units meet NEMA 4X/IP65
requirements for indoor use, when properly installed. The units are intended
to be mounted into an enclosed panel. Prepare the panel cutout to the
dimensions shown in Figure 1, Panel Installation & Removal. Carefully apply
the adhesive side of the panel gasket to the panel cutout. Remove the panel
latch and cardboard sleeve from the unit. Discard the cardboard sleeve. The
unit should be installed with the bezel assembly in place and the bezel screws
tightened slightly. Insert the unit into the panel cutout. While holding the
front of 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 [79 N-cm]). Do NOT over-tighten the screws.
Note: The installation location of the controller is important. Be sure to keep it
away from heat sources (ovens, furnaces, etc.), away from direct contact with
caustic vapors, oils, steam, or any other process by-products in which
exposure may affect proper operation.
Caution: Prior to applying power to the controller, the internal AC power
selector switch must be set. Damage to the controller may occur if the switch is
set incorrectly.
