Ambient conditions
Altitude 0–4000 m (0–13000 ft) above sea level, when the net-
work is not corner grounded: Voltage class B5
0–3000 m (0–10000 ft) above sea level: Voltage class 07
without AFE supply
0–2000 m (0–6500 ft): Voltage class 07 with AFE supply
Above 1000 m (0–3000 ft): Derating of maximum sur-
rounding operating temperature by 0.5 °C per each 100
m (0.9 °F per each 330 ft) is required.
