Using AC Power with DC Power Backup

Procedure

✔Make sure that the DC power source wires are not powered (i.e., the circuit breakers are open).

✔The ends of the DC power source wires (14–18 AWG solid or stranded wire) must be stripped of insulation. If they are not stripped of insulation, strip the tip of each wire (about 1/2 inch or 12.7 mm in length) before plugging the wire into the appropriate connector on the –48V input terminal block. Ensure that each wire is fully inserted into the terminal (until it can go no further).

To supply both AC and DC power to the 8620 chassis for power redundancy:

1.Plug the AC power cord into the IEC 320 receptacle labeled AC INPUT ( ).

2.Insert the wires for the DC power source into Terminal B and securely fasten each wire by tightening the screw above it. The insulation should be fully within the terminal block and no bare wire should be exposed outside of the block.

NOTE:

You should clearly label these power source wires as –48V and RTN respectively.
