A 15-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 enclosure. 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 120 or 240 VAC, 50 or 60 Hz, single-phase power through a
15 Amp circuit breaker. 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. 

Use the following procedure to install the AC power wiring:

1. Locate the AC power cable that is provided separately with the enclosure.

2. Route the power cable between the AC power port, located on the underside of the

enclosure and the nearest AC power junction box as shown in 

. It may be

necessary to install a new junction box if an existing junction box is not available. 

Note: It is recommended that an AC outlet be installed near the enclosure for powering
tools and test equipment. This outlet must include a GFCI device for protection. 

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.
