A.5 Drive Derating Data
330 YASKAWA TM.V1000.01 V1000 Drive Installation & Start-Up Manual (Preliminary 01-19-07)
Figure A.3 is provided as a quick reference to aid in derating the drive above
specified altitude.
Note: This derate applies only to the inverter. However, if the inverter is placed in a
pressurized cabinet so that the internal pressure is maintained at the value of
atmospheric pressure at 3300ft. then there is no need for derate. Example: Heat sink
is exposed to the outside and is not under positive pressure in an enclosed cabinet
with forced air cooling or an air-conditioning system. In such a case, derating is
required.

Motor Derating
Consult the motor manufacturer for the applicable altitude de-rating factor before
applying the motor. As a general guideline, consult the NEMA standard MG 1-
14.04 (Operation of AC and DC Fractional- and Integral-HP Motors and
Generators at Altitudes Above 3,300 feet (1000 meters). However, the motor
manufacturer's specific de-rating data is always preferable.
