Option 1: Using a DC Power Connector and Cable
If the power source equipment is supplying DC power, use a DC cable at a suitable
gauge given the distance from the fuse panel to the host, and assemble the provided
DC power connector onto the cable.
Figure 3-6: DC Power Connector
The following table describes the maximum distance between the power source
equipment and the unit. The values assume a maximum recommended loss of 3%. The
voltages shown are voltages at the power sourcing equipment.

Use a 2 or 3-wire cable with stranded bare copper wire with unshielded outer jacket.
The nominal voltage required at the host is 48 VDC (with a range of 40 VDC to 58
VDC).

Asse mbling and Connecting the DC P ow e r Cable
Before connecting DC power to the hdHost PS, verify that the power source supplies
48 VDC to the unit, and that any intermediate connections are secure.
To assemble the DC power cable, you need:
DC cable connector (provided)
Multi-conductor #12 AWG to #16 AWG stranded bare copper with unshielded
outer jacket
Stripping tool
Flat head screwdriver
