Agency Certification
Altitude Derating Above 1000 meters (3300 feet) derate at 6% of RWC rated amperes per 1000 meters (3300
feet) elevation to 4000 meters (13200 feet) maximum.
Heat Dissipation Use the cable length and drive carrier frequency to find the approximate RWC losses for your
system. Vertical movement inside the loss band will be dependent on exact cable type and
motor load.
