3-2 Making the Electrical Connections
Check serial tag voltage/amperage requirements and make sure your electrical service
conforms before making any electrical connections. Make sure that all three phases are wired
correctly.
A separate fuse system is recommended but not absolutely necessary. Bring properly sized
power leads and grounds from a fused disconnect to the unit. If you use fuses, make sure that
they are dual-element, time-delay fuses, sized according to your electrical code. Refer to the
technical specifications in the Appendix for horsepower, voltage, phase, and frequency
requirements to determine the size and rating of the supply cable required.
Carefully check the diagrams packed with the machine. All internal wiring has been done at
the factory. All safety interlocks have been verified to be functional before shipment. The
only connection left to be made, is the electrical power source to the machine at the control
enclosure.
Use the following procedure to complete the electrical connections:
1. Check that the limit switches are closed.
2. Turn switch ON at main power supply.
3. Press the ON switch for at least 3 seconds.
4. With the electrical power ON, check that the motor rotates in a clockwise direction at
the viewing window. If the direction of rotation is incorrect interchange any two
power lines. Verify the direction of rotation for all available sockets.
Caution! Incorrect motor rotation reduces the quality of grinding considerable and
may damage the motor.
