5.1 Power Supply Wiring (AC / DC Powered Versions)
The majority of the AW-100 systems will be powered via the AC/DC power supply.
Connect the AW-100 main unit and if applicable the optional Radio Unit system to
suitable AC power sources as shown in Figure 5-1. Use only the AC / DC power supply
and AC cables provided by AirWalk to ensure continued safe operation.

5.2 Grounding
Grounding of the AW-100 system to the local site grounding system is essential for both
safety and proper RF performance. The grounding of the IP-RAN system should be
integrated with the overall site grounding plan as designed by the site planning engineer.
A “halo” perimeter grounding system is recommended for sites equipped with external
antennas that are subject to possible lightning strikes.
A ground strap is provided with each AW-100 system and each RU system to allow
bonding to a ground bus bar or to a common rack grounding point. Each ground wire is
installed on the AW-100 main unit and on the RU amplifier system as shown in Figure 5-
2.
Customer to provide and install (crimp to existing lug) ground cable (AWG 10-12)
between system and the common ground.
Other ground cabling or bus bars used in site installation must be suited to the purpose
and meet any applicable local electrical codes.
Ground connections should be tested for continuity after installation.
