Notes
- Module rating are for IP 00 degree protection
- For IP 30 protection of panel derte the current rating by 10%
- For IP 40 protection of panel derate the current ratings by 20%
- Fro IP 50 protection of panel derate the current ratings by 20% However, please note, IP 50 protection can be offered for range of module's 11-40, 70 which are natural cooled. or requirements of IP 50 protection for other ratings, please refer to manufacturing unit.
