Installing the NEMA 4X Hatch
ET 355 Monitor HL
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
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.
11.
Wire all connectors and attach locking devices to
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.
13.
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 should require about three rounds
of tightening.
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

!
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 18-
1J2 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.
Important
If you need to examine wiring inside the hatch, take off the
removable plate (or extended hatch cover) from the hatch.
