Installing the NEMA 4X Hatch
ET 350 Monitor (Models ET 350R and ET 350L3)
Intended Use
When properly installed using the materials provided, and according to these instructions, the NEMA 4X Hatch is intended to provide for the ET 350 monitor (specifically, ET 350R and ET 350L3 monitors) a NEMA 4X/IP66 seal on all sides. The ET 350L3 monitor is also UL listed for use in Pollution Degree 3 environments
Warning
Read and understand all safety information before installing and using this product.
To reduce the risk of electric shock or fire which could result in serious personal injury or death:
!Follow all product and accessory installation instructions.
!Wiring installation should be done by a journeyman electrician and must comply with federal and local electrical codes.
!Any servicing or other procedures not described in this document are to be performed only by 3M Touch Systems service personnel.
!Properly install the monitor with a NEMA 4X gasket that is undamaged and effective.
!Properly install the NEMA 4X gasket to achieve a NEMA 4X/IP66 seal.
!After making an opening, make sure that there are no metal shavings in the hatch.
!Choose fittings and a power cable that provide adequate strain relief for communications and power cables.
!A cable/fitting combination will have to be found that meets local electrical requirements and the requirements for a NEMA 4X seal.
!When connecting power with fixed field wiring for the ET 350L3 monitor and the ET 350R monitor, the power cable must be double insulated. A clear, flexible insulator (supplied) must cover the portion of the cable that is not double insulated when connecting to a terminal strip connector..
Caution
To reduce the risk of electric shock or fire which may result in minor or moderate injury or cause property damage:
!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.

Attaching the gasket
Important
If you ordered the ET 350L3 monitor, the hatch gasket was attached at the factory. Proceed to “Preparing the hatch for cables”.
1.Place the monitor face down on a horizontal work surface (covered with foam pads or other material to protect the monitor’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.
Note. The gasket is not rectangular. The side of the gasket that is placed near the back of the monitor is shorter than the side that is placed near the front of the monitor.

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.
Important
!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.
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).
Important
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.
If you want to make your own cables, refer to pin-outs in the 3M Dynapro ET 350 Monitor User’s Installation Guide.
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.
