USB plug
USB type B “device” plug
Connection to a PC is done 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 ground. Use only an isolated laptop/PC as the 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 203°F ± 41°F [95°C ±
5°C]. An overload temperature cannot be reset until the temperature of the heatsink is below 158°F ± 41°F [70°C ± 5°C] (Guideline - these
temperatures may vary for different power sizes, enclosures, etc.). The adjustable frequency drive has an auto derating function to avoid its
heatsink reaching 203°F [95°C].
•
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).
