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

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.

Tools and material required
You will need the following tools and material to

! Sealed Listed (UL) conduit hubs that meet
NEMA 4X/IP66 ratings

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.
