12. Connect wire 1 to J19 (J18 for 400 V CE and 480 V CSA power supplies). Orient the wires such that the ring
connector for wire 1 is closest to the power board, and the connector for the white wire is closest to the head of the
screw. Turn the ring connector for wire 1 upside down so that the slight bend in the ring connector base creates a
little space between the wire and the board. Tighten the screw to 23.0 kg∙cm (20 inch∙pounds).
