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. Before installing the IM into the panel, the user should
first become familiar with the unit. It may also be desirable to program the
unit for the application. When programming is complete, all parameters will
be saved in nonvolatile memory. The Program Disable (PGM.DIS.) terminal
should be connected to COMM. to prevent accidental or unauthorized
programming changes.
The unit meets NEMA 4/IP65 requirements for indoor use, when properly
installed. The units are intended to be mounted into an enclosed panel. Two
mounting clips and screws are provided for easy installation. Consideration
should be given to the thickness of the panel. A panel which is too thin may
distort and not provide a water-tight seal. (Recommended minimum panel
thickness is 1/8".)
After the panel cut-out has been completed and deburred, carefully slide
the panel gasket over the rear of the unit to the back of the bezel. Insert the
unit into the panel. As depicted in the drawing, install the screws into the
narrow end of the mounting clips. Thread the screws into the clips until the
pointed end just protrudes through the
other side. Install each of the mounting
clips by inserting the wide lip of the clips
into the wide end of the hole, located on
either side of the case. Then snap the clip
onto the case. Tighten the screws evenly
to apply uniform compression, thus
providing a water-tight seal.
CAUTION: Only minimum pressure is
required to seal panel. Do
N O T
overtighten screws.
PANEL INSTALLATION
SELECT AC POWER (115/230 VAC)
The AC power to the unit must be selected for either 115 VAC or 230 VAC.
The selector switch is located through an access slot on the side of the case
(See figure above or label on case). The unit is shipped from the factory with
switch in the 230 VAC position.
