Extron Electronics Flexible Conduit Adapter Kit User Manual
Flexible Conduit Adapter Kit
Installation Guide
The Flexible Conduit Adapter Kit provides a convenient means to replace the IEC power cord of the Extron PS 124 12 VDC,
4 A power supply (part #60-1022-01), the XPA 1002 (part #60-899-01), or the XPA 2001 (part #60-850-01 and -11) power
amplifier with conduit, where required by local codes.
The Flexible Conduit Adapter Kit includes the following parts:
• One EMT adaptor plate
• One 6' long electrical conduit
• Three 7.5' 14-gauge power wires with spade connectors
• One UL rated zip tie wrap
• Three auxiliary crimp style spade connectors designed for 14- to 16-gauge wires
WARNINGS: The circuit breaker used for this connection should be rated no less than 15 amps when 14 gauge power
wire is used, or 20 amps when 12 gauge wire is used.
This unit must be installed in accordance with the National Electrical Code and with all local codes.
An ALL-POLE MAINS SWITCH with a contact separation of at least 3 mm in each pole must be incorporated
in the electrical installation of the building. The installation must be carried out in accordance with all
applicable installation rules.
Installation and service must be performed by a qualified electrician only.
CAUTIONS: Make sure that the XPA amplifier or the PS 124 power supply and its attached source device, as well as all
output devices, are turned off and disconnected from the power source before you begin.
A UL listed electrical distribution box is recommended for the termination of the conduit opposite the
PS 124 power supply or the XPA amplifier. See “UL Requirements,” below.
NOTE: Extron recommends using a UL-rated crimp tool to terminate the spade connectors, if this is needed. One
recommended choice is the Molex crimp tool (Molex part #19285-0008).
UL Requirements
The Underwriters Laboratories (UL) requirements listed below pertain to the installation of the flexible conduit onto a
PS 124 power supply, an XPA 1002, or an XPA 2001.
• This unit must not be used beyond its rated voltage range.
• This unit must be wired to a UL listed distribution box.
NOTE: The UL approved electrical distribution box is not included with the XPA amplifier, the PS 124 power supply,
or the Flexible Conduit Adapter Kit; the installer is responsible for obtaining and installing the distribution
box.

Installing the Flexible Conduit Cable on a PS 124
Install the flexible conduit cable assembly to the PS 124 as follows:
1. Unplug the IEC power cord from the PS 124.
2. Remove and retain the two Phillips head screws that secure the IEC plate to the PS 124 rear panel.

4. Carefully lift the top cover up, taking care not to remove it completely.
CAUTION:
Rough handling of the top cover can disconnect or damage the wiring that connects the front
panel LED.
5. Use a standard screwdriver to loosen the screws holding the hot and
neutral
wires on the side of the terminal block
nearest the IEC plate (see figure 3, below).
6. Unscrew the IEC connector ground wire from the ground wire nut on the bare metal bottom of the PS 124 enclosure.
7. From the rear panel end, pull the IEC connector out of the enclosure.
8. Thread the 12- or 14-gauge power wires through the length of the electrical conduit tube.

9. Install the EMT adapter plate (with the conduit attached) into the opening from which you removed the IEC connector
in step 7 (see figure 4, on the next page). Use the Phillips head screws that you removed in step 2 to attach the EMT
adapter plate.
