Temperature Derating
For High Altitude
601/604/607 US Supplement
When the altitude of the installation site exceeds 1000 m (3300 ft.)
above sea level, the rated ambient temperature can be decreased as
an alternative to decreasing the rated output current. Use curve 2 for
models ACx 601-0025-2, ACx 601-0050-2 and ACx 601-0070-2 when
they are in IP54 enclosures.
