Without derating: 1000m (3280 ft)
With derating: 1000 m (3280 ft) to 4000 m (13123 ft), derate the
output current by 1% for each 100 m (328 ft).
Maximum altitude above sea level
Regarding IEC 61800-5-1 compliance, the default maximum alti-
tude is 2000m (6562ft). When the installation site is at an altitude
of 2000m (6562 ft) to 4000 m (13123 ft), contact Danfoss for fur-
ther information.
1) Ensure maximum rate of change of temperature 0.1°C/min (0.18°F/min) to avoid condensation.
4.3 Fuses and Circuit Breakers
For proper protection of the installation cable and the drive, fuses and/or circuit breakers must be used. If short circuit occurs, fuses and
circuit breakers protect the power cable and limit the damage to the drive and components connected to the drive.
When using circuit breakers, be aware of the limitation to the short-circuit capacity of the supply, and follow the installation instructions
from the manufacturer. The short-circuit rating must comply with the values given in Table 32.
