Step 2
Tighten the wire-clamp screws to prevent the wires from loosening, as shown below in
Figure 2.6: Power Terminal Block
Caution:
Only use copper conductors, 60/75°C, tighten to 5 in-lbs.
The wire gauge for the terminal block should range between 18~20 AWG.
Grounding Note
Grounding and wire routing help limit the effects of noise due to electromagnetic interference
(EMI). Run the ground connection from the ground screw to the grounding surface prior to
connecting devices. The grounding screw symbol is shown blow in Figure 2.7.

Caution:
Using a shielded cable achieves better electromagnetic compatibility.
