• Tighten terminal screws using a flat or cross-head screwdriver.
Each screw should be turned tight enough to immobilize the
wire’s end. Excessive tightening can strip the terminal screw.
The torque applied to each screw should not exceed 0.565 Nm
(5 in-lb) for each terminal.
• Follow system grounding and wiring guidelines found in your
SLC 500 Installation and Operation Manual, publication
1747-UM011.
