NOTES:

1.For terminal# 1 through 6, the use of ring terminals size #6 (M3.5) is recommended using stranded wire size AWG 18-14. Tighten all screws to a torque of 12 Lb-in (1.36 Nm).

2.For terminal# E, the use of ring terminal size #8 (M4) is recommended using stranded wire size AWG 18-14. Tighten screw to a torque of 12 Lb-in (1.36 Nm).

3.Use the “Chassis Ground” terminal connection for grounding the unit. “Earth Ground” should be used as secondary grounding source only.

4.Be sure to replace the clear plastic electrical safety shield before applying power to the unit.
