Two input power junction boxes and interconnecting cables provide under floor connection for the two
input power feeds. Power terminal blocks are provided in each junction box for the connection of the
input power conductors and a parity-sized ground conductor. The junction boxes are NEMA 1 enclo-
sures. A main input cable assembly is provided for connection between the unit and the junction box.
The cable length between the unit and junction box is 10 feet (3 meters) long.
See 5.2 - Input Junction Box Installation—Optional on page 10 for more information and specifi-
