2.7.5Installing AC Power
Note: Power interfacing for the RAN must be performed by a licensed electrician.
Prime power for the RAN is 240 VAC, 20 Amps, single phase. A separate service disconnect
and lightning arrestor for each RAN must be installed with proper grounding. An electric meter
is optional depending on local agreements.
A non-connectorized #14 AWG 3-wire power cable is provided with the RAN cabinet for the
AC power connections. The power cable is connected to a wiring harness within the cabinet and
is approximately 20 feet (6 meters) long. The stub end of the cable must be routed out of the
cabinet through conduit to an external junction box (not provided). At the junction box, the
power cable must be connected to the AC power system wiring. The RAN electrical input fitting
is located on the right rear of the cabinet, labeled “AC.”
The AC power cable provides three wire leads for Line, Neutral, and Ground connections. All
AC wires must be run within conduit. The interface at the RAN is a 1 in. (2.54 cm) 90 degree
receptor elbow.
For installation of AC power, the following materials are required (customer provided):
• Electrical conduit
• Conduit fittings
• Connector sealant material
The following tools are required to perform this procedure:
Note: All electrical work must comply with local codes and requirements. A locally
licensed electrical contractor is best qualified to perform this work. For operation at less
than 20 Amps, consult with ADC Technical Service.
Danger: Use extreme caution when working with high voltage AC power. Ensure all power is
disconnected before working on power circuits.
Use the following procedure to install the AC power wiring:
1. Install outdoor conduit between the the AC power junction box and the AC power fitting
(rigid 90 degree receptor elbow) on the back of the cabinet.
2. Use a UL approved outdoor conduit connector (not provided) to connect the conduit to the
AC power junction box.
Note: A reducer fitting must be provided to accommodate any size change to the conduit.
3. Route the AC power cable through the conduit to the AC junction box.
4. Install the required AC power supply wires between the AC junction box and the AC
circuit breaker box (by the junction box not within the RAN).
5. Strip off the insulation from the AC power cable wire leads and from the AC supply wires
and connect the AC power cable wires to the AC supplier cable.
6. Connect the AC power to the AC wiring harness.
7. At the AC circuit breaker box, connect the AC power supply load wire(s) to a 20 Amp
circuit breaker.
8. Place the circuit breaker in the ON position and then test the connectorized AC power
cable within the cabinet for proper voltage levels and correct polarity.
9. Place the circuit breaker in the OFF position when testing is complete.
2.7.6Installing Backup Batteries (Extended or Glitch)
Backup batteries for the RAN may be either two-hours-extended or five minutes glitch. The
batteries will need to be installed and under charge before they will be able to provide full
service. Battery storage life is one year in an environmentally controlled area. Batteries should
be checked prior to installation. Each battery should measure 12.6 V or greater across terminals.
Any battery that measures less should not be used. Refer to the battery manufacturer’s manual
for specific information including charging recommendations, tests, and maintenance.
2.7.6.1Battery Safety Rules
