electrical wiring to prevent damage to equipment or potential injury to personnel.  

All installations requiring cable trays shall be the responsibility of the RFN 
customer or its customer. Cable tray requirements vary from site to site and are 
not specific to the RadioFrame System. All cable tray installations shall receive 
permits from and be inspected by the local municipality governing tenant 
improvements, including mechanical and electrical inspections. Site plans, 
procurement, installation, grounding/bonding, and inspecting of the cable tray 
shall be the responsibility of the RFN customer or its customer. 

To install a remote ACU, first mount the unit then connect the ACU to the NCU 
and each associated RFU. Repeat the following two procedures for each remote 
ACU. 

Mount each remote Airlink Chassis Unit (ACU) as follows: 

1  Find these items in the ACU shipping container: one ACU, four mounting 

screws, and one 120VAC power cord. 

2  Mount the ACU only in an EIA-standard compliant (19”) rack using all 4 

screws provided. Refer to the site documentation for the exact location of the 
ACU. For safe operation, follow these guidelines: 

• 

Do not mount the ACU in any orientation other than that specified in the 
following illustration.  

• 

Mount the ACU so that both the front and the back are accessible.  

• 

If the mounting holes do not line up, adjust the ACU up or down until the 
mounting holes line up. 

 

 

Caution 

Do not block the air vents on the sides or rear of the ACU. 

 

3  Plug the ACU into an approved power source with the provided power cord.
