Motor nameplates can be stamped for any voltage within the listed
supply voltage range. Chillers shall not be selected at voltages above
or below the listed supply voltage range.
2. To establish electrical data for your selected voltage, if other than
listed voltage, use the following formula:
listed voltage
RLA = listed RLA x
selected voltage
listed voltage
OLTA = listed OLTA x
selected voltage
selected voltage
LRA = listed LRA x
listed voltage
Example: Find the rated load amperage for a 575-v motor listed at
1.14 amps per kW input for use at 550 volts.

Compressor motor controllers
Compressor motors, controls, and accessories require the
use of starting equipment systems specifically designed for
23 Series Chillers. Refer to Carrier Engineering Require-
ment Z-375.
Capacitors/power factors
Power factor considerations may indicate use of capacitors.
Properly sized capacitors improve power factors, especially
at part load. Contact your local Carrier sales representative
for further information on power factors.
