3-3 Electrical Connections
It is extremely important that the machine is correctly wired into the plant power source
by a licensed electrician. (See wiring diagram.)
All electrical equipment must be properly grounded in accordance with local and national
codes to protect personnel from electrical shock. A fusible, lockable disconnect between
the plant power source and the machine electrical cabinet is highly recommended.
CAUTION! Before connecting the power, check that the power cable size and capacity
corresponds to the horsepower and amp load indicated on the granulator label and that the
disconnect switch is in the OFF position.
Unless otherwise specified, the granulator has been wired for 480 volts, 60 Hz, 3 ph.
The power cable from the plant source can be run directly to the control panel or through
the base of the machine. To run the power cable through the base of the granulator,
perform the following steps:
1. Open the back cover and insert the power cable from underneath the granulator.
2. Pass the power cable through the appropriate hole and insert it into the control
panel through a connector placed at the base.
3. Connect the three-phase wires to the appropriate terminals of the main switch and
connect the ground wire to the provided terminal near the main disconnect
switch. (See figure below.)
