Extron electronic XTRA SERIES manual UL Requirements

The optional Flexible Conduit Adapter Kit consists of:

•One EMT adapter plate

•One 6-foot long electrical conduit

•Three 7.5 feet, 18-gauge spade connector power wires

•One UL-rated zip tie wrap

•Three auxiliary crimp style spade connectors designed for 14- to 16-gauge wires

NOTE: If needed, Extron recommends using a UL-rated crimp tool to terminate the spade connectors. One recommended choice is the Molex crimp tool.

The kit provides a convenient means to replace the IEC power cord of the XPA with conduit, where required by local codes.

UL Requirements

The UL requirements listed below pertain to the installation of the flexible conduit onto a XPA 1002 or XPA 2001.

•This unit is not to 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 either the XPA or the Flexible Conduit Adapter Kit. The installer is responsible for obtaining and installing the box.

Installing the Flexible Conduit Kit

ATTENTION: Electrostatic discharge (ESD) can damage IC chips even though you cannot feel it. You must be electrically grounded before touching anything inside the XPA. A grounding wrist strap is recommended.

Install flexible conduit to the XPA by following the steps below.

1.Unplug the IEC power cord from the power amplifier.

2.Remove the 8 screws from the top and sides of the XPA and lift off the cover (see figure 5).
