CAUTION
Connection to PC is carried out via a standard host/device USB cable.
The USB connection is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
The USB connection is not galvanically isolated from protection earth (ground). Use only isolated laptop/PC as
connection to the USB connector on frequency converter or an isolated USB cable/converter.
Protection and Features
•
Electronic thermal motor protection against overload.
•
Temperature monitoring of the heat sink ensures that the frequency converter trips if the temperature reaches
95° C ±5° C. An overload temperature cannot be reset until the temperature of the heat sink is below 70° C ±5° C
(Guideline - these temperatures may vary for different power sizes, enclosures etc.). The frequency converter has
an auto derating function to avoid its heatsink reaching 95° C.
•
The frequency converter is protected against short-circuits on motor terminals U, V, W.
•
If a mains phase is missing, the frequency converter trips or issues a warning (depending on the load).
•
Monitoring of the intermediate circuit voltage ensures that the frequency converter trips if the intermediate circuit
voltage is too low or too high.
•
The frequency converter is protected against earth (ground) faults on motor terminals U, V, W.
