4.4 ELECTRICAL REQUIREMENTS
SEE FIGURE 3-1 THROUGH 3-4 ON THE FOLLOWING PAGES.
Ö
CAUTION: TO PREVENT DAMAGE TO THE MACHINE AND DANGER TO THE OPERATOR,
ALL ELECTRICAL CONNECTIONS SHOULD BE MADE BY A QUALIFIED ELECTRICIAN.
THIS MACHINE OPERATES WITH LIQUID COOLANT AND MUST BE GROUNDED IN
ACCORDANCE WITH NATIONAL ELECTRIC CODES.
All machines are wired for three phase power. The motors and coolant pumps are dual voltage and will
operate on either 230 or 460 volts; the Variable Speed Drive is not. If the machine is not the same voltage
as your plant voltage, you will have to replace the variable speed drive, change the primary leads on
the transformer and rewire the motor. To insure satisfactory performance, the supply voltage should be
(+ or -) 10% of the motor voltage rating. Check the motor data tag for full load current requirements.
Single phase motors are not available; however, the Variable Speed Drive can be used as a phase
converter. For supply lines ten feet (303 cm) or shorter, we recommend 12 gauge wire. For lines longer
than ten feet (303 cm), we recommend 10 gauge wire. We do not recommend supply lines over twenty feet
(606 cm) in length.
