Page 4

The TLA meets NEMA 4X/IP65 requirements for indoor use to provide a

watertight seal in steel panels with a minimum thickness of 0.09 inch, or

aluminum panels with a minimum thickness of 0.12 inch. The units are intended

to be mounted into an enclosed panel. It is designed so that the units can be

stacked horizontally or vertically. The bezel assembly MUST be in place during

installation of the unit.

Instructions:

1. Prepare the panel cutout to the dimensions.

2. Remove the panel latch from the unit. Discard the cardboard sleeve.

3. Carefully remove the center section of the panel gasket and discard. Slide

the panel gasket over the unit from the rear, seating it against the lip at the

front of the case.

4. Insert the unit into the panel cutout. While holding the unit in place, push the

panel latch over the rear of the unit, engaging the tabs of the panel latch in

the farthest forward slot possible.

5. To achieve a proper seal, tighten the

panel latch screws evenly until the

unit is snug in the panel, torquing

the screws to approximately 7 in-lbs

(79 N-cm). Over tightening can

result in distortion of the panel, and

reduce the effectiveness of the seal.

Note: The installation location of the

TLA is important. Be sure to keep it

away from heat sources (ovens,

furnaces, etc.), and away from

direct contact with caustic vapors,

oils, steam, or any other process

byproducts in which exposure may

affect proper operation.

Multiple Unit Stacking

The TLA is designed for close spacing of multiple units. Units can be stacked

either horizontally or vertically. For vertical stacking, install the panel latch with

the screws to the sides of the unit. For horizontal stacking, the panel latch

screws should be at the top and bottom of the unit. The minimum spacing from

center line to center line of units is 1.96" (49.8 mm). This spacing is the same

for vertical or horizontal stacking.

Note: When stacking units, provide adequate panel ventilation to ensure that

the maximum operating temperature range is not exceeded.

Caution: Disconnect power to the unit and to the output control

circuits to eliminate the potential shock hazard when removing the

bezel assembly.

Unit Removal Procedure

To remove a unit from the panel, first loosen the panel latch screws. Insert

flat blade screwdrivers between the latch and the case on either side of the unit,

so that the latches disengage from the grooves in the case. Push the unit through

the panel from the rear.

Removing Bezel Assembly

The bezel assembly must be removed from the case to replace the output

board. To remove the bezel assembly, insert a flat blade screwdriver into the pry

slot on either side of the unit. Twist the screwdriver handle until the unit is

ejected enough to allow removal.

Caution: The bezel assembly contains electronic circuits that can be damaged

by static electricity. Before removing the assembly, discharge static charge on

your body by touching an earth ground point. It is also important that the

bezel assembly be handled only by the bezel itself. Additionally, if it is

necessary to handle a circuit board, be certain that hands are free from dirt,

oil, etc., to avoid circuit contamination that may lead to malfunction. If it

becomes necessary to ship the unit for repairs, place the unit in its case

before shipping.

Installing Bezel Assembly

To install the bezel assembly, insert the assembly into the case until the bezel

is fully seated against the lip of the case. Properly installing the bezel assembly

is necessary for watertight sealing.
