Figure 21 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
7. Insert the twisted-pair wire leads into the terminal block line and neutral connections.
8. Insert the wire (labeled number 1 in Figure 21 on page 44) lead into the neutral wire connection and the wire (labeled
number 2 in Figure 21 on page 44) lead into the line wire connection.
Ensure that only wire with insulation extends from the connectors. See Figure 21 on page 44.
9. Tighten the line and neutral terminal block screws to 8 in.-lb torque.
note: Do not exceed 10 in-lb torque.
10. 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).
