Figure B-44 AC/DC Power Input Terminal Block Wire Connections to a DC Source
Warning An exposed wire lead from a DC-input power source can conduct harmful levels of electricity. Be sure
that no exposed portion of the DC-input power source wire extends from the power and relay
connector. Statement 122
Step 7 Insert the twisted-pair wire leads into the terminal block line and neutral connections. Insert the wire
(labeled number 1 in Figure B-44) lead into the neutral wire connection and the wire (labeled
number 2 in Figure B-44) lead into the line wire connection. Ensure that only wire with insulation
extends from the connectors. See Figure B-44.
Step 8 Tighten the line and neutral terminal block screws.
Note The torque should not exceed 2.2 in-lb (0.25 Nm).
Step 9 Connect the red wire to the positive pole of the DC power source, and connect the black wire to the return
pole. Ensure that each pole has a current-limiting-type fuse rated to at least 600 VAC/DC (such as the
KLKD Midget fuse).
