VLT AQUA Drive
Instruction Manual
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).
• 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.
