with Flexible Conduit • Installation Guide
This guide provides instructions for replacing the power cord of an Extron Cable Cubby or Hideaway Surface Access (HSA) enclosure
with conduit (not provided) where required by local codes.
UL Guidelines
The Underwriters Laboratories (UL) guidelines listed below pertain to the installation of exible conduit into an Extron Cable
Cubby or HSA.
WARNING: Installation and service must be performed by a qualied electrician only.
• This unit is not to be used beyond its rated voltage range.
• This unit must be wired to a UL-listed distribution box. The installer is responsible for obtaining and installing the box.
• This unit must be installed in accordance with the National Electrical Code and with all local codes.
Removing the Old Cable
WARNING: Ensure power is removed from the Cable Cubby or HSA by disconnecting
the power cable from the electrical outlet.
1. If the power module is installed in a Cable Cubby, remove the power module. If a
clamshell is installed on the base of the HSA, remove the clamshell.
NOTE: If necessary, remove the
Power Module
Cable Cubby or HSA from the
table in which it is installed.
2. Unplug any devices plugged into the
sockets of the power module or HSA.
3. For the Cable Cubby power module,
remove and retain the four screws on
the side and remove the side plate (see
image at right).
4. Cut the power cable at approximately
0.5 inch below the sealing nut on the
power module or HSA.
5. Remove the sealing nut.
6. Remove and retain the two screws on the power input plate on the bottom

of the power module or HSA. Gently pull out the plate and remove it from
the cut portion of the cable, leaving the wiring attached to the power
module.
NOTE: If necessary, push the cable through the cord grip so that it is
not pulled by the plate.
7. Remove the lock nut and cord grip
from the power input plate.

Assembling the Flexible Conduit and Power Input Plate
1. Insert the threaded conduit tting into the power input plate
(see image at right for dimensions). The power input plate
contains a ½ inch trade size knockout.
NOTE: Make sure the length of the conduit and wires
extends from the power module or HSA location to the
AC distribution box.
WARNING: Ensure power is removed from the UL-listed
AC distribution box.
2. Fasten a conduit nut (not provided) on the threaded conduit tting.
3. Insert replacement wires through the conduit. Pull the wires out of the
conduit assembly to the length of approximately 3 inches.
Installing the Replacement Wires
1. Cut and strip the green, black, and white wires in
the power module or HSA at the necessary length.
NOTE: The length of the stripped wires
should allow for connection with the
replacement wires (see step 2) and for
fitting into the power module or HSA
enclosure (see step 3).

2. Take the replacement wires and twist together the two
supply (white) wires (one from the power module or
HSA and one from the conduit assembly), the two return
(black) wires, and the two ground (green) wires. Twist a
wire nut (not provided) onto each twisted pair.
3. Place the power input plate assembly on the base of
the power module or HSA, gently tucking the power
cables and wire nuts into the enclosure. Use tie wraps if
necessary.
ATTENTION: If inserting the replacement wires into
an HSA enclosure, be careful not to damage the
wires when closing the lid of the HSA. Close the lid
3
carefully and make sure that it does not contact the
wires inside the enclosure.
NOTE: If necessary, reorient the conduit nut and
wires for the best fit.
4. Secure the power input plate, using the screws.
5. For the power module, secure the side plate in place, using the Phillips head screws.
6. Remove power from the AC distribution (junction) box.
WARNING: Ensure power is removed from the UL-listed AC distribution box before connecting the power wires and
conduit. Hazardous voltages are present in the AC distribution box.
NOTE: Ensure the AC distribution box is rated for and equipped with a 15-amp circuit breaker.
