Using a Single DC Power Source

Procedure

✔Make sure that the DC power source wires are not powered (that is, the circuit breakers or fuses are open at the source).

✔The ends of the power source wires (14–18 AWG or 2.5 mm2 solid or stranded wire) must be stripped of insulation. If the wires are not stripped, strip the tip of each wire (about 1/2 inch or 13 mm in length) before inserting the wire into the appropriate terminal on the –48V input terminal block.

To supply 48 VDC power to the 8620 chassis from a single 48 VDC power source:

1.Insert the following wires into Terminal A 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.

2.Clearly label these power source wires as –48V and RTN respectively.

Insert Power Source A’s . . .	Into the . . .
