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

For safety purposes, observe the following DO’s and DON’T’s when installing the batteries or performing battery tests and maintenance:

•DO use qualified personnel only for battery maintenance

•DO follow all battery and charger manufacturer maintenance instructions
