USB plug
USB type B “device” plug
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. Use only isolated laptop/PC as connection to the USB connec-
tor on the frequency converter or an isolated USB cable/converter.
Protection and Features:
•
Electronic thermal motor protection against overload.
•
Temperature monitoring of the heatsink ensures that the frequency converter trips if the temperature reaches a predefined level. An overload
temperature cannot be reset until the temperature of the heatsink is below the values stated in the tables on the following pages (Guideline -
these temperatures may vary for different power sizes, frame sizes, enclosure ratings etc.).
•
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 faults on motor terminals U, V, W.
