Dc Power Copper Conductors Warning - Juniper PTX5000 Hardware Manual

• Incorporate an easily accessible disconnect device into the facility wiring. In the United States and
Canada, the –48 VDC facility should be equipped with a circuit breaker (see
PDU Electrical and External Circuit Breaker Specifications" on page 166
with the National Electrical Code in the US and the Canadian Electrical Code in Canada. Be sure to
connect the ground wire or conduit to a solid office (earth) ground. A closed loop ring is
recommended for terminating the ground conductor at the ground stud.
Each –48-VDC facility DC source input power cable connected to a 60-A DC PDU must be equipped
with a current-limiting fuse or circuit breaker (see,
Circuit Breaker Specifications" on page 166
facility DC source circuit breaker must be 80 V minimum. We recommend an 80 A–rated circuit
breaker or current-limiting fuse for each 60-A DC power cable.
• A DC-powered router is equipped with a DC terminal block that is rated for the power requirements
of a maximally configured router. To supply sufficient power, terminate the DC input wiring on a
facility DC source (see
Specifications" on page 166
• Run two wires from the circuit breaker box to a source of 48 VDC. Use appropriate gauge wire (see
"PTX5000 AC and DC PDU Electrical and External Circuit Breaker Specifications" on page 166
details).
