11. Remove the work lead connector screw at J21 and the white wire connector screw at J19 (J18 for 400 V CE and
480 V CSA power supplies).

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).
13. Connect wire 2 to J21. This time, put the connector for the work lead closest to the power board and put the ring
connector for wire 2 closest to the head of the screw. Torque the screw to 23.0 kg cm (20 inch-pounds).
14. Replace the rear panel and secure it with the screw. Replace the Mylar barrier in front of the power board. Replace
the cover.
