- Surrounding air temperature as specified in tables. From 40 ºC to 45 ºC (104 ºF to 113 ºF) for frame size H: 1 % of current derating for each Celsius degree above maximum temperature as specified

in item above. From 50 ºC to 60 ºC (122 °F to 140 °F) for frame sizes B, C and D models and from 45 ºC to 55 ºC (113 ºF to 131 ºF) for frame sizes E, F, G and H models: 2 % of current derating for each

Celsius degree above maximum temperature as specified in item above.

- Relative air humidity: 5 % to 95 % non-condensing.

- Altitude: 1000 m (3.300 ft). Above 1000 m (3.300 ft) up to 4000 m (13.200 ft) the output current must be derated by 1 % for each 100 m (330 ft) above 1000 m (3.300 ft).

- Ambient with pollution degree 2 (according to EN50178 and UL508C).

(2) One overload each 10 minutes.

(3) The information provided about the inverter losses are valid for the rated operating condition, i.e., for rated output current and rated switching frequency.

(4) Only for frame sizes B, C and D: the switching frequency may be automatically reduced to 2.5 kHz depending on the operating conditions (surrounding air temperature, output current, etc.) - if

P0350 = 0 or 1.

If it is desired to operate always in 5 kHz, set P0350 = 2 or 3 and derate the output current. For additional information, consult WEG.

(5) Motor power ratings are merely a guide considering 575 V, 60 Hz for 500 to 600 Vac supply, or 690 V, 50 Hz for 660 to 690 Vac supply, IV pole WEG motors. The adequate inverter sizing must be

based on the used motor rated current.
