11.5 Terminal block

We recommend using stranded wire to connect to the terminal
block. Crimp a ferrule over stranded bare wire to ensure a good
connection.
Consult the chart below for the recommended torque amounts on
the terminal block screws.
Screw Diameter (mm) Torque (N•cm) Torque (lbf•in)
2.8 30-40
2.8-3 35-50
3-3.2 50-60
3.2-3.6 60-80
3.6-4.1 90-120
4.1-4.7 120-180
4.7-5.3 150-200
Using the proper torque specifications to secure wire to the wiring
block helps to avoid personal loss or property damage.
See 14, "Specifications", pg. 9 for information on the proper
wire gauge size.
