Connections
This section describes general examples of how to connect the input and output ports on the WRH.
Main Power and Grounding
Local regulations need to be followed for the main power connection. WRHs are approved in accordance with
EN and UL/cUL regulations. This is, however, only valid if a classified power cord is used. For the Nexus FTto
meet th
ese regulations you must select one of the following classified and approved cord types:
❑ EN – H 05 W5 - F HMR
❑ UL – AWM
Style 2587
❑ CSA– AWM 1 A/B 11 A/B
For outdoor use, the power cord should meet at least IP65 enca
psulation requirements. Do not turn the main
power on until you are ready to commission the WRH.
Fiber Optic and RF Connections
Fiber optic and RF cable connections should be verified both internally and externally before powering up the
equipment. This section illustrates the general internal connections of the WRH. Verify these connections with
the as-built drawings and documents for your specific system configuration. Table 3-1 lists the steps to add
the external connections to the WRH.
WARNING: For WRHs supplied from the main power source, the main outlet must be
grounded.
