2. Check whether the ambient temperature of the VFD in actual use is lower than
-10°C. If yes, use heating facilities.
Note: For the cabinet VFD, the ambient temperature means the air temperature
inside the cabinet.
3. Check whether the altitude of the VFD in actual use exceeds 1000m. If it exceeds
1000m, derate 1% for every increase of 100m. When the altitude exceeds 3000m,
consult the local Kruger dealer or office for details.
4. Check whether the humidity of the actual usage site exceeds 90% and
condensation occurs. If yes, take additional protective measures.
5. Check whether the actual use site may be exposed to direct sunlight or may have
the chance of ingress of foreign objects. If yes, take additional protective
measures.

2. Check whether correct accessories are selected for the VFD, the accessories are
correctly and properly installed, and the installation cables meet the
requirements of all components (including the reactor, input filter, output reactor,
output filter, DC reactor, braking unit and braking resistor).
3. Check whether the VFD is installed on non-flammable materials and the
