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 non-volatile
memory. The Program Disable (PGM.DIS.) terminal should be connected to
COMM. to prevent accidental or unauthorized programming changes.

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 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.
The unit meets NEMA 4/IP65 requirements for indoor use, when properly
installed. The units are intended to be mounted into an enclosed panel with a
gasket to provide a water-tight seal. 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
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.
