Special Conditions; Derating For Ambient Temperature And Switching Frequency; Derating For Low Air Pressure; Options For Vlt ® Hvac Basic Drive Fc 101 - Danfoss VLT HVAC Basic Drive FC 101 Quick Manual

Quick Guide
All inputs, outputs, circuits, DC supplies and relay contacts are galvanically isolated from the supply voltage (PELV) and
other high-voltage terminals.

1.8 Special Conditions

1.8.1 Derating for Ambient Temperature
and Switching Frequency
The ambient temperature measured over 24 hours should
be at least 5°C lower than the max. ambient temperature.
If the frequency converter is operated at high ambient
temperature, the continuous output current should be
decreased. For derating curve, see VLT
Guide MG18C.

1.8.2 Derating for Low Air Pressure

The cooling capability of air is decreased at low air
pressure. For altitudes above 2000 m, contact Danfoss
regarding PELV. Below 1000 m altitude no de-rating is
necessary, but above 1000 m the ambient temperature or
the maximum output current should be decreased.
Decrease the output by 1% per 100 m altitude above 1000
m or reduce the max. ambient temperature by 1° per 200
m.
