4.6 AC Power Wiring Installation
A 20-foot connectorized 3-wire cable (also available in lengths of 40, 60, or 100 feet) is provided
for the AC power connections. The connectorized end of the cable connects to the AC power port
located on the bottom of the unit. The stub end of the cable must be routed to an external junction
box (not provided) for permanent connection to the AC power system wiring.
The AC power source must supply between 100 and 240 VAC, 50 or 60 Hz, single-phase power
through a circuit breaker or fuse. The AC power cable provides three wire leads for line, neutral,
and ground connections. The power cable is rated for indoor or outdoor use and must not be placed
within electrical conduit as this will impede the cooling of the cable during usage. The electrical
junction box and any conduit, wire, and fittings required must be provided by the installer.
Note: All electrical work must comply with local codes and requirements. A locally
licensed electrical contractor is best qualified to perform this work. For additional
information, consult with the ADC Technical Assistance Center.
Danger: Use extreme caution when working with high voltage AC power. Ensure all power is
disconnected before working on power circuits.
