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 ground. Only use an isolated laptop/PC as the connection to the USB
connector on a VLT AQUA 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.). VLT AQUA Drive has an auto-derating function to prevent 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).
• Monitoring of the intermediate circuit voltage ensures that the adjustable frequency drive trips if the intermediate circuit voltage is too low or
too high.
• The adjustable frequency drive is protected against ground faults on motor terminals U, V, W.
