APPENDIX “A” - 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.
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.

PANEL INSTALLATION
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
min. panel thickness is 1/8" [3.2 mm].)
Cut the panel opening to the specified dimensions. Remove burrs and
clean around the panel opening. 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 NOT
overtighten screws.
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 the
switch in the 230 VAC position.
CAUTION: Make sure the AC selector switch is set to the
appropriate position before applying power to the unit. Damage
to the unit may occur if the AC selector switch is set incorrectly.
