NOTICE!
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 ground protection. Use only isolated laptop/PC as connection to
the USB connector on the adjustable frequency drive or an isolated USB cable/drive.
Protection and Features:
•
Electronic thermal motor protection against overload.
•
Temperature monitoring of the heatsink ensures that the adjustable frequency drive trips if the temperature
reaches a predened level. An overload temperature cannot be reset until the temperature of the heatsink is below
the allowed values.
•
The adjustable frequency drive is protected against short-circuits on motor terminals U, V, W.
•
If a line phase is missing, the adjustable frequency drive trips or issues a warning (depending on the load).
•
Monitoring of the intermediate circuit voltage ensures that the adjustable frequency drive trips if the intermediate
circuit voltage is too low or too high.
