Flush Mount Installation Instructions
Caution: The chassis of the XD unit can fall into
the wall cavity if the four screws attaching the
faceplate to the chassis are removed. Use caution
not to drop the unit into the wall during installation
or service.
The XD unit is approximately 4.0" deep. The unit
will not mount flush unless there is at least 3.75" of
clearance. The unit is designed to mount flush on
a typical 2 x 4 stud wall with drywall.
Depending on the depth of the wall cavity, there
are two installation procedures. The preferred
installation utilizes Back Flange Mounting.
The back flange supports the weight of the XD
unit and service procedures are greatly simplified.
If this can not be accomplished, an alternate
Front Flange Mount is possible. Please note that
the front flange installation may create servicing
difficulties in the future.
Preferred Installation - Back Flange Mounting
Mount as close as possible to the protected panel.
Create a wall opening approximately 6 3/4" x 6
1/16". See Figure 6. (Rotate dimensions 90° as
appropriate depending on orientation.) Configure
an appropriate backing plate inside the wall cavity
3 3/4" from the wall face such that the unit will be
supported from its back. Note the mounting holes
on the back flange attachments. Be careful not
to drop the unit into the wall. Configure electrical
conductor and conduit connection consistent with
the installation instructions on page 6. Preplan
connections such that they are completed prior
to fastening the unit to the backing plate. Install
faceplate/cover prior to energizing and testing the
unit.
Alternate Installation - Front Flange Mounting
This method is not preferred for installation as
servicing is substantially more difficult. Extra care
should be taken to NOT DROP the XD unit into the
wall. Mount as close as possible to the protected
FLUSH MOUNT "/FM" (PREFERRED INSTALLATION)

Prepare Wall and SPD
STEP 2
Insert into Wall Mount the SPD
panel. Create a wall opening approximately 6 3/4"
x 6 1/16". See Figure 6. (Rotate dimensions 90°
as appropriate depending on orientation.) Preplan
and pre-connect electrical conductor and conduit
connections such that they are completed prior to
fastening the unit to the wall. Note that removing
the four screws attaching the front faceplate to the
unit chassis will cause the XD to fall inside the wall.
UL 1283 required language concerning the
installation of EMI Filters
a) An insulated grounding conductor that is
identical in size and insulation material and
thickness to the grounded and ungrounded
circuit supply conductors, except that it is green
with or without one or more yellow stripes, is to
be installed as part of the circuit that supplies the
filter. Reference should be made to Table 250-
122 of the National Electrical Code regarding the
appropriate size of the grounding conductor.
b) The grounding conductor mentioned in item a is
to be grounded to earth at the service equipment
or other acceptable building earth ground such as
the building frame in the case of a high-rise steel-
frame structure.
c) Any attachment-plug receptacles in the vicinity
of the filter are to be of a grounding type, and the
grounding conductors serving these receptacles
are to be connected to earth ground at the service
equipment or other acceptable building earth
ground such as the building frame in the case of a
high-rise steel-frame structure.
d) Pressure terminal
connectors and soldering lugs used in the
installation of the filter shall be identified as
being suitable for the material of the conductors.
Conductors of dissimilar metals shall not be
intermixed in a terminal or splicing connector
where physical contact occurs between dissimilar
conductors unless the device is identified for the
purpose and conditions of use.
