Mount the Fiber CAP L
Mounting a CAP L with a Hybrid Fiber Splice Box Kit
The CAP L Hybrid Fiber Splice Box Kit (CommScope PN 7781091-xx) provides a connection solution for both
power and optical signals to a CAP L. For Fiber CAP Ls, you have the option to use composite cable to transport
signals from a TEN or Classic CAN via fiber and power from a remote DC supply, and then use the CAP L
Hybrid Fiber Splice Box Kit to terminate the power and fiber at the CAP L.
The CAP L is designed to be supplied by two LPS (Limited Power Source, <100VA) circuits. By using LPS
circuits, some electrical code requirements for installing the power cables are relaxed. The CAP L supports
a combined/parallel circuit approach. That is, two LPS circuits can be combined in parallel and the CAP L
supplied by a single, higher power source. In either configuration, all electrical and safety code
requirements must be followed.
It is the responsibility of the customer/installer to observe the local regulations of the DC service provider
and to comply with Limited Power Source (LPS) requirements where applicable.
Prepare for CAP L Hybrid Fiber Splice Box Kit Installation
1
Follow the steps in "Unpack and Inspect the CAP L and Optional Accessories” on page 23 .
2
Refer to "Determine the CAP L Installation Site” on page 17 to determine the mounting location, which
must be able to support the weight and dimensions of the CAP L.
3
Refer to "Mounting Orientation for Wall Mounts” on page 29 to determine the mounting orientation of the
CAP L.
Assembling and Wiring the Hybrid Fiber Splice Box
The following subsections describe how to assemble the Hybrid Fiber Splice Box and then how to wire it to
provide power to the CAP L:
•
"Assembling and Wiring the Hybrid Fiber Splice Box” on page 43 tells you how to place the wires into the
Hybrid Fiber Splice Box.
•
You then need to follow one of the following procedures that meets the powering requirements of this
installation.
–
"Wire a Hybrid Fiber Splice Box for 4-Wire Power with Limited Power Source” on page 47
–
"Wire a Hybrid Fiber Splice Box for 2-Wire Power without Limited Power Source” on page 49
