3.1 Mounting the Repeater to the Wall
•
The ZXr repeater should be wall mounted in a position that allows clear visibility of displays and easy
access to operating controls. The height above floor level should be chosen such that the LCD is just
above normal eye level (approximately 1.5 metres).
•
DO NOT site the ZXr repeater where there would be restricted access to the internal equipment and
cabling / wiring connections.

Recommended Aperture Dimensions
•
The Bezel Kit is supplied with a dedicated back box
that has three fixing holes on the rear wall and two
fixing holes on each side. This procedure covers the
use of the rear fixing holes but can be applied to the
side fixings.
•
Make a recess in the wall large enough for the back
box to be inserted easily and without unnecessary
force. Allow for space required for cable entry into
the back box. With the bezel still attached to the
back box, offer the assembly to the recess to check
for correct depth and clearance. Repeat this
process until the correct depth and clearance have
been achieved.
•
Support the bezel / back box assembly in the
desired position in the recess and mark the three
screw fixing positions (X) as shown opposite.
Remove the assembly from the recess. Using an
appropriate sized drill bit, drill and plug the three
holes to take up to No. 8 (4mm) wood screws.
Alternatively, use the side fixing holes (Y).

Dimensions
To avoid distortion of the back box
when preparing knockouts, place the
appropriate back box face on a
supporting surface (e.g. work bench).
•
Prepare all required knockouts and fit cable glands
as required (Refer to Wiring Installation Section).
•
Orientate the bezel / back box assembly correctly, off it to the recess, then feed the cables through the
glands and take up any excess slack. Secure the assembly in position using appropriate sized screws –
do not use countersunk-headed screws. To avoid distorting the back box, do not over tighten.
•
Prepare the repeater for fitting by removing the appropriate knockouts as required. Insert one of the
supplied cable grommets into the upper knockout on the rear wall of the repeater (this knockout is
required / used for an earth connection).
•
Correctly orientate the repeater, hold the door open and off the repeater to the installed bezel / back box
assembly. Feed all cables through the prepared knockouts and full insert the repeater into the bezel /
back box aperture. Use the four M4 SEM screws supplied in the kit to secure the repeater to the
assembly (for location of the repeater mounting holes, refer to the Direct Mounting instructions below).
Top Left of Enclosure
•
Connect the free end of the back box earth lead to the earth
connector provided on the inside of the repeater enclosure (top
left corner). Use a suitably sized cross-headed screwdriver to
tighten at the earth point. Ensure good connection is made.
