
Switching frequency derating
The output current is calculated by multiplying the current given in the rating table by
the derating factor given in the table below.
Note: If you change the minimum switching frequency with parameter 97.02
Minimum switching frequency, derate according to the table below. Changing
parameter 97.01 Switching frequency reference does not require derating.

Altitude derating
In altitudes 1000…4000 m (3300…13120 ft) above sea level, the derating is 1% for
every 100 m (330 ft).
The output current is calculated by multiplying the current given in the rating table by
the derating factor k, which for x meters (1000 m <= x <= 4000 m) is:
Check the network compatibility restrictions above 2000 m (6562 ft), see Installation
site altitude on page 159 . Check also PELV limitation on relay output terminals above
2000 m (6562 ft), see sections Isolation areas, R0…R4 (CCU-11): on page 155 and
Isolation areas, R5…R9 (CCU-12): on page 156 .
