Figure 2-6. Power and Ground Properly Connected
Making the Power Connection
The power wires should be 14 AWG. Smaller wires may be used, down to 18 AWG, but
verify that they meet your local electrical requirements.
Connect the power to the unit as follows.
1.Remove the plug portion of the power connector by loosening the two captive
mounting screws.
2.Strip back 1/4" off the insulation of the wires that will connect the unit to the
power source.
3.Loosen saddle screw and insert each conductor firmly into a terminal hole of the
plug (note: this connection is not polarity sensitive.)
4.Visually inspect that no strands of wire are straying out of the hole, potentially
shorting to ground or the other conductor. Tighten the saddle screws until the
wires are secure.
5.Re-insert the plug into the power connector and secure the two captive
mounting screws.
ELECTRICAL WARNING: Ensure that power is disconnected from wiring prior
to handling! Check the voltage rating next to the power connector - verify that
it matches the power source.
