CAUTION:
frequency described in the motor nameplate. The motor will operate
successfully under running conditions at rated load with a variation in the
voltage or the frequency up to the following:
1. When the variation in the voltage value does not exceed 10% above
or below the specified in the motor nameplate, with all phases
balanced.
2. When the variation in the frequency value does not exceed 5%
above or below the specified in the motor nameplate.
3. When the sum of the voltage and the frequency values does not
exceed 10% above or below the specified in the motor nameplate
(provided frequency value variation does not exceed the 5%).
However, performance within these voltage and frequency variations
will not necessarily be in accordance with the standards established for
operation at rated voltage and frequency.
WARNING:
personnel, taking the following warnings into consideration:
1. The electrical supply shall be disconnected and preventive action
against accidental connection must be taken.
2. The motor shall be properly connected to a grounding circuit. Refer
to the NOM-001-SEDE and NEC or any other local electrical code.
