Installation Of Conduit To The Back Can; Figure 22 Conduit For Protected Wiring To Can; Figure 23 Redeploying The Plug For Wires; Entering From Conduit - Community Distributed Design D4LP Installation And Operation Maintenance Owner's Manual

Required tools:

Installation of conduit to the back can

• One hammer and knockout punch tool
• One step-bit for adjusting knockout
diameter (optional)
• Safety glasses, gloves and other personal
safety gear are recommended as this pro-
cess involves striking metal parts and chip-
ping away debris around the knockouts.
1. All Distributed Design Series loudspeaker
back cans have dual-diameter knockout
strain relief fittings on each side. These
fittings each measure:
• 21/32 (17mm) to accommodate 3/4
"
(19 mm) fittings
• 15/16 (24 mm) to accommodate 1
"
fittings
Conduit fitted to one side of the can (an
additional knockout strain relief on the opposite
side of the can allows the connection wiring to be
carried through to subsequent cans)
When you use conduit to bring wires to the
side port(s) of the back can, you can loosen
the screws in the green plug to remove the
factory-installed wires from the internal
terminal block jumpers (see Figure 22), then
insert wires from the conduit(s) and tighten
the screws. In any case, the rest of the wiring
details are the same as shown in Figure 21.

Installation and Operation Manual
• Additionally, the top cover has a 3/4
(19 mm) knock-out.
2. The knockout strain relief ports are
opened with a hammer and punch using the
same techniques for removing knockouts in
standard electrical boxes. A step-bit can be
used to modify the diameter of the hole to
accommodate larger conduit sizes.
3. Insert appropriate fittings and tighten
sufficiently for wire path concealment and
strain relief, in accordance with applicable
codes.
4. You can use flexible or rigid conduit (if
permitted by local electrical codes).
Conduit fitted to the top cover plate of the can,
which has a knockout strain relief for this
purpose
