Note:
(1)
Steady state rated current in the following conditions:
- Indicated switching frequency. It is not possible to use the CFW11W G2 inverter with switching frequency of 2.5 kHz, 5 kHz and 10 kHz.
- Ambient temperature around the inverter as specified in
Chapter 3 INSTALLATION AND CONNECTION on page 3-1 . For higher temperatures, limited
to 55 º C, the output current must be derated by 0,5 % for each º C above the maximum temperature specified.
- Coolant input temperature as specified in Chapter 3 INSTALLATION AND CONNECTION on page 3-1 . For higher temperatures, limited to 55 º C, the
output current must be derated by 1 % for each º C above the maximum temperature specified.
- Coolant flow as specified in Chapter 3 INSTALLATION AND CONNECTION on page 3-1 .
- Air relative humidity: 5 % to 95 % non-condensing.
- Altitude: 1000 m. Above 1000 m up to 4000 m, the output current must be derated by 1 % for each 100 m above 1000 m.
- Environment with pollution degree 2 (as per EN50178 and UL508C).
- For operation of the inverter in steady state with output frequencies between 0 and 10 Hz, derate the rated output current by 35 %.
(2) One overload every 10 minutes. Table 8.1 on page 8-2 presents only two points of the overload curve (actuation time of 1 min and 3 s). The complete
overload curves of the IGBTs for Normal Duty (ND) and Heavy Duty (HD) are presented in Figure 8.1 on page 8-3 . Depending on the inverter operating
conditions, such as ambient temperature around the inverter and output frequency, the maximum operating time of the inverter with overload may be shorter.
