INPUT ELECTRICAL
CONNECTIONS
Before installing the machine, check that input supply voltage, phase, and frequency are the same as the machine's voltage, phase, and frequency as specified on the machine's rating plate.
The
THREE PHASE POWER INPUT CONNEC- TION FOR THE PRO-CUT 80
The
CONVERTING THE
To convert to single phase power, the
1.Connect the green lead to ground per U.S. National Electrical Code.
2.Connect black and white leads to power.
3.Wrap red lead with tape to provide 600V insulation.
WARNING
Machine damage could result if the machine is improperly configured for the Input Voltage applied.
INPUT POWER CORD CONNECTOR INSTALLATION
A cord connector provides a strain relief for the input power cord as it passes through the left rear access hole. The cord connector is designed for a cord diam- eter of .40 - 1.03 in (10.2 - 26.2mm) if it becomes nec- essary to install a different input cord.
CORD REMOVAL:
1.Unplug line cord from the receptacle.
WARNING
NOTE: DO NOT PERFORM THE NEXT STEP UNTIL THE HIGH VOLTAGES INSIDE THE MACHINE HAVE BEEN ALLOWED TO DISSIPATE, APPROXIMATELY TWO MINUTES.
2.Remove wraparound by unscrewing the eleven screws on the case sides and top.
3.Unscrew the four screws that hold the line switch onto the case front.
4.Pull the line switch out of the case front.
5.Angle the line switch so the nuts on the switch can be loosened.
6.Remove the cord from the switch.
7.Remove the nut, lock washer, plain washer and green lead off of the ground screw assembly.
8.Loosen the cable connector on the case back.
9.Pull the line cord out of the machine.
CORD INSTALLATION:
1.Feed the new cord through the cable connector and into the machine.
2.If the ground screw assembly is loose, tighten the assembly to the base before installing the new ground lead. Install the green lead on the ground screw assembly, replace the plain washer and lock washer, then tighten nut. Install in accordance with all local and national electrical codes.
3.Connect the new cord to the switch, observing the color code on the wiring diagram.
4.Feed the line switch back into case front.
5.Replace the four screws that hold the line switch onto the case front.
6.Tighten the cable connector on the case back.
7.Replace wraparound and tighten the eleven screws on the case sides and top.
8.Connect the new input power cord to a fused three phase power supply. Make sure the green lead is connected to the panel and the panel is connected to a good earth ground. Install in accordance with all local and national electric codes.
NOTE: Fusing requirements of the machine input will change, depending on whether the machine is used on single phase or three phase. Use the chart in the TECHNICAL SPECIFICATIONS to change the fuses to the proper value.
