WARNING
Turn power off before installing or removing terminal. All electrical
work should be done according to appropriate electrical codes.
1. Strip wire insulation to length specified in chart
to the right, according to conductor size.
2. Firmly grasp wires, making sure insulation ends
are even and tightly bundled. (wires may be
twisted or untwisted). Slip connector over wire
tips.
3. Turn connector onto wires in a clockwise
direction until secure.
4. To remove, turn connector counter-clockwise.
