location to achieve single point grounding). The Smart Jack and T1 suppressor 
are located on the Telco board near the T1 line entrance to the site. The CSU is 
located in main rack. The CSU is grounded to the main rack and subsequently to 
the master ground bar approximately 15 wire-feet away. 
3.9.2 Power 
Cabling 
All electrical wiring for the site must meet the requirements of NEC and all 
applicable local codes. 
3.9.2.1 
AC Power Cabling 
This section describes only the AC power. All grounding shall limit the exterior 
connections to a single point. The transmission wire entrance for the GPS and 
the telco service and board must be installed on a common wall to have true 
single point grounding. 
 
 
Caution 
Facility AC wiring within junction boxes, receptacles, and switches shall be performed by a 
licensed and bonded electrical contractor. Personnel safety and liability hazards can result 
from AC wiring performed by installation personnel other than an electrical contractor. 
 
When an open equipment rack is used, hardwiring of power is not always 
possible. Mounting a dedicated simplex receptacle or receptacle assembly on the 
rack may be the most convenient method of supplying power, especially if 
multiple pieces of equipment are mounted on the rack. This is also a convenient 
way to install personal protection type 3 SPD devices (such as Motorola PN 
RLN4924A) to the equipment. 
These receptacle assemblies can be pre-manufactured and mounted to the top 
face of an equipment rack. Mounting can also use a fabricated power pole 
mounted between racks. 
Equipment that contains its own AC power supply is typically fitted with a 
standard grounded line cord. Where this equipment is used, the rack shall be 
equipped with a dedicated simplex receptacle or receptacle assembly.  
Use only the power cables provided by RadioFrame Networks. Use of any other 
cable is strictly prohibited and may void the warranty and/or cause electrical fire 
and damage. 
 
 
Caution 
Under no circumstances shall consumer-grade power outlet strips be used In any 
Installation. Extension cords of any type shall not be use for connecting line power to 
communications equipment.
