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-45) lead into the neutral wire connection and the wire (labeled

number 2 in Figure B-45) lead into the line wire connection. Ensure that only wire with insulation

extends from the connectors. See Figure B-45.

Step 8 Tighten the line and neutral terminal block screws.

Note The torque should not exceed 10 in-lb.

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).
