3M Dynapro 355 Installation Instruction

Installing the NEMA 4X hatch

ET 355 Monitor HL

Intended Use

When properly installed according to the instructions,
the NEMA 4X hatch is intended to provide a NEMA

TM

4X/IP66 seal on all sides for the 3M Dynapro
ET 355 Monitor HL (hereafter, ET 355 monitor).

The ET 355 monitor is a component. After the
monitor is installed with the NEMA 4X hatch, the
whole system of which it is a part must be inspected
to confirm seal ratings and compliance with all local
electrical codes.

Product safety information

DANGER

TO REDUCE THE RISKS ASSOCIATED WITH FIRE AND EXPLOSION

WHICH, IF NOT AVOIDED, WILL RESULT IN DEATH OR SERIOUS INJURY
AND/OR PROPERTY DAMAGE:

! Do not open the monitor while the circuit is live unless the area

is known to be non-hazardous.

! Do not operate the monitor’s OSD switches, DIP switch, KVM

extender remote board, or potentiometer on the KVM extender
remote board unless the area is known to be non-hazardous.

WARNING

TO REDUCE THE RISKS ASSOCIATED WITH ELECTRICAL SHOCK, FIRE

AND EXPLOSION WHICH, IF NOT AVOIDED, COULD RESULT IN DEATH
OR SERIOUS INJURY AND/OR PROPERTY DAMAGE, IF THE NEMA 4X
HATCH IS PART OF YOUR APPLICATION:

! Choose Listed (UL) conduit hubs that are rated to NEMA

4X/IP66 standards, are suitable for use in hazardous locations,
and provide adequate strain relief for wiring.

! After making an opening in the NEMA 4X hatch, make sure that

there are no metal shavings in the hatch.

! Properly install the monitor so that it is environmentally sealed

to the NEMA 4X/IP66 standard. Do not use the ET 355 monitor
with mounting options that are not rated for NEMA 4X/IP66 in
environments that require such a seal.

! Properly install the ET 355 monitor with a NEMA 4X gasket that

is clean, undamaged, and effective.

! When closing the hatch of the 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 voided.

Power supply, wiring methods

For product safety information about power supply
and wiring methods for the ET 355 monitor, refer to

Tools and material required

You will need the following tools and material to
install the NEMA 4X hatch to the ET 355 monitor:

! No. 1 Phillips torque screwdriver

! Sealed Listed (UL) conduit hubs that meet

NEMA 4X/IP66 ratings

! A punch or drill to make openings in the hatch

Steps

To mount a NEMA 4X hatch on the ET 355 monitor,
follow these steps:

1. Decide on the number and locations of hatch

openings required for your application.

2. If the ET 355 monitor is in a hazardous location,

make sure that the location is free of hazardous
gases.

3. Disconnect power and other connections.

4. Make openings in the back of the hatch. If you

need three or fewer openings, you can use as
guides the three indentations on the back of the
hatch. If you need four openings, you will need
to decide how best to space them.

Openings can be made anywhere on the back of
the hatch, as long as the hatch can open and close
freely on its hinges after conduit hubs are
installed.

Important

! Do not make openings in the removable plate, the top, or

the bottom of the hatch, or in the extended hatch cover
(if you are using the extended hatch cover).

! Be sure that any opening you make is 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.

! Be sure that openings do not have sharp edges that

could damage wiring.

! Provide appropriate Listed (UL) conduit hubs that, when

installed according to the manufacturer’s instructions
and the National Electrical Code or local electrical code,
will provide a NEMA 4X/IP66 seal.

5. Attach conduit hubs through the hatch openings

and tighten them to torque settings recommended
by the manufacturer to achieve a NEMA
4X/IP66 rating.

11. Wire all connectors and attach locking devices to

Important

! Flexible conduit allows for greater flexibility during

installation of the NEMA 4X hatch than does rigid
conduit. However, wiring methods must be in
accordance with Class I, Division 2 wiring methods
Article 501-4(b) or the National Electric Code, NFPA 70
for installations in the U.S., or as specified in Section 18­1J2 of the Canadian Electrical Code for installations
within Canada and in accordance with the authority
having jurisdiction.

! If you use rigid conduit, first attach the monitor to the rigid

conduit and then place the monitor in its final position.
3M Touch Systems recommends that either the monitor
be mounted close to a junction box or that a junction box
be installed close to the monitor.

! The closer the monitor is to a junction box, the easier it

is to make the final connection and mounting of rigid
conduit.

provide strain relief.

12. Close and fasten the hatch by loosely attaching

the four #6-32 Phillips screws. Check to make
sure that the screw holes in the edges of the hatch
line up with the threaded holes in the monitor
enclosure.

Important

If you need to examine wiring inside the hatch, take off the
removable plate (or extended hatch cover) from the hatch.

13. Using a No. 1 Phillips torque screwdriver,

gradually tighten diagonal pairs until all the
screws are equally tight at a torque of 7 inch­pounds. This should require about three rounds
of tightening.

6. Install the monitor on its mounting so that it is

rigidly fixed.

7. Temporarily insert the hinge pins of the hatch

and fasten with the #6-32 Phillips screws
provided.

8. Bring the conduit to the hatch, aligning it with

each hub, and attach the conduit to the hub

14. While the monitor is still in a location that is free

of hazardous gases, connect power to the monitor

15. While the monitor is still in a location that is free

of hazardous gases, adjust on-screen display
(OSD) settings as desired. For information on
using OSD controls, refer to the ET 350 Monitor
User’s Installation Guide.

according to the manufacturer’s instructions.

9. Remove the monitor from its mounting.

10. Pull wiring through the conduit, making sure that

there is enough slack in the wiring to allow the
hatch to open and close fully on its hinges
without straining the wiring or connectors.
