common (COM) lead are provided for each power supply. Applying

power activates the NO and NC contacts. When power to the

equipment is lost or a power supply fails, the relay deactivates,

forcing the NO contacts closed and the NC contacts open. Connect

COM to NC or NO, depending on your office equipment. Torque

connector wire set screws to 4.5 to 8.0 inch lb (0.5 Nm to 0.9 Nm).
