When closing the hatch of the ET unit, make sure that it closes flush and that the hatch screws do not bind when they are attached. If the hatch is not closed properly, the NEMA 4X seal may be compromised and the warranty invalidated. CAUTION To reduce the risk associated with electric shock or fire that may result in personal injury or property damage:! After making an opening for cables, make sure that there are no metal shavings in the hatch.! Use round cables that fit the diameter range of the cable fitting, as shown in Table A, to meet local electrical requirements and the requirements for a NEMA-4X/IP66 seal. To reduce the risks associated with electric shock or fire which, if not avoided, could result in death or serious injury and/or property damage.! Wiring installation should be done by a journeyman electrician and must comply with federal and local electrical codes.! Properly install the ET unit with a NEMA 4X gasket that is undamaged and effective.! Properly install the ET unit so that it is environmentally sealed to the NEMA 4X/IP66 standard. Do not use an ET unit that is not rated for NEMA 4X/IP66 in environments that require such a seal. 1

2 Installing the NEMA 4X Hatch Equipment Materials supplied The following materials are supplied for installing the NEMA 4X hatch:! 1 NEMA 4X hatch (with removable plate attached). For details about the supplied cable fitting components, see Table A. Tools required! 1 NEMA 4X extended hatch cover To install the NEMA 4X hatch, you will need the following:! Horizontal work surface with a padded cover or foam pads to protect the front bezel and the display of the unit.! Flat blade screwdriver with 3/16-inch blade! No. 1 Phillips torque screwdriver! 1 19/32" (15 mm) open-end wrench! 1 15/16" (24 mm) open-end wrench Attaching the gasket If you ordered the ET 350L3 monitor, the hatch gasket was attached at the factory. Proceed to Preparing the hatch for cables.! 1 gasket! 4 #6-32 Phillips screws! Cable fitting components (3 large sizes and 3 small sizes of each component are provided):! Locking nut! O-ring! Body hex with compression sleeve! Sealing nut 1. Place the ET unit face down on a horizontal work surface (covered with foam pads or other material to protect the unit s bezel and touch screen), with the access hatch facing you. 2. Before removing the gasket backing, position the gasket over the recessed edge of the access hatch opening so that you know which way it fits. 2

The side of the gasket that is placed near the back of the ET unit is shorter than the side that is placed near the front of the unit. Back of monitor 8. When you are satisfied with the fit, use your fingers to press the gasket firmly into place all around the opening of the access hatch. Preparing the hatch for cables You can make up to four openings through the back of the hatch. Do not make openings in the removable plate, the top or bottom of the hatch, nor in the extended hatch cover (if you are using the extended hatch cover). Front of monitor Be sure that the openings you make are free of burrs and that the surface around the hole is smooth and free of debris. This will help ensure that the installed fittings seal properly _co 3. Start at one corner and peel away just enough of the backing to expose about 1 inch of adhesive on each side of the corner.! The adhesive under the backing is very delicate. To be sure that you do not remove the adhesive with the backing, use a razor knife to separate the backing from the adhesive.! Do not remove the entire backing at once. Start at one corner, lift and peel back some of the backing only, as described below.! Do not stretch the gasket. This can cause the adhesive layer to come away from the gasket. 4. Place the gasket on the recessed edge of the access hatch, with the backing side down. Line it up with the edge of the opening in the access hatch, then gently press the corner with the exposed adhesive into place. Don t press it down firmly yet. 5. With the gasket gently adhering at the corner, peel the backing away from the corner carefully, a little bit at a time, gently pressing the gasket into place around the edge of the access hatch as you go along. Don t press it down firmly yet. 6. Continue until you have removed all of the backing and the gasket is lightly tacked into place around the opening of the access hatch. 7. Make sure that the entire surface of the gasket is in contact with the recessed edge of the access hatch, without bumps or ripples. If you want to make your own cables, refer to pin-outs in the user s guide for your ET unit. Connecting cables to the hatch To ensure safe, certifiable connections and a complete seal using one of the sealed fittings provided (Table A), follow the steps in this section.

4 Installing the NEMA 4X Hatch Connecting supplied sealed fittings 1. Make a clearance hole. Clearance holes can be made anywhere on the back of the hatch, as long as the hatch can open and close freely on its hinges after the cables and/or cable fittings are installed. Note: There are three indentations on the back of the hatch that may be used as guides when creating holes. However, these are only guides; if you need four holes, you will need to decide how best to space them. For ET 350 monitors only: The number of holes needed will depend on whether your monitor has a KVM extender (maximum of four holes) or not (three holes). Table B shows the clearance holes required in each case Table B: For ET 350 monitors only: Cable clearance holes required for monitors without and with KVM extender Opening for this cable ET 350 monitor without KVM extender ET 350 monitor with KVM extender Power!! Serial! VGA! CAT5! Mouse! Keyboard! If the diameter of the cable is close to the ranges of both the small and large fittings shown in Table A, try running the cable through the smaller fitting before beginning to connect the fittings. If the cable will go through the small fitting without being forced, 3M Touch Systems recommends using that fitting. 2. The cable fitting comes loosely assembled. Disassemble the cable fitting into its four components: locking nut, o-ring, body hex (which encloses the compression sleeve), and sealing nut. 3. Install the o-ring onto the surface of the body hex and then insert the body hex (with o-ring attached) into the clearance hole on the outside of the hatch. 4. On the inside of the hatch, attach the locking nut to the body hex. 5. Holding the body hex stationary with a wrench, handtighten the locking nut and then use a second wrench to tighten the locking nut until the cable fitting is held in place securely (see Table A for suggested torque values). 6. Slide the sealing nut onto the cable and then, from the outside of the hatch, feed the cable through the cable fitting. 7. Gently screw the sealing nut onto the body hex, but do not tighten it. Leave the sealing nut loose to allow the cable to move through the fitting. 8. Slide the cable through the body hex and into the hatch until you are satisfied with the amount of cable inside and outside of the hatch. Make sure there is enough slack in the cable to allow the hatch to fully open and close on its hinges without straining the cables or connectors. 9. Holding the body hex stationary with a wrench, handtighten the sealing nut and then use a second wrench to tighten the sealing nut until the wire is held securely in place (see Table A for suggested torque values). 4

Insert the hinge pins of the hatch into the hinges of the ET unit, close the hatch and make sure that the screw holes in the edges of the hatch line up with the threaded holes in the unit s enclosure. If you need to examine cables inside the access hatch, take off the removable plate (or extended hatch cover) from the hatch. Replacing cables To replace a cable, disassemble the fitting by following these steps: 1. Using a wrench to hold the body hex stationary, loosen the sealing nut with a second wrench. 2. Grip the disconnected cable and pull while turning the cable in a counter-clockwise direction. The new cable you install will require a new fitting. Closing the hatch To close the hatch, follow these steps: 1. Attach cables to their respective connectors. 2. Close and fasten the hatch by loosely attaching the four #6-32 Phillips screws. 3. Using a No. 1 Phillips torque screwdriver, gradually tighten diagonal pairs until all the screws are equally tight at a torque of 7 inch-pounds. This may require about three rounds of tightening. 5
