7.3 Mains Supply

Mains supply (L1, L2, L3)
Supply voltage
Mains voltage low/mains drop-out:
•
During low mains voltage or a mains drop-out, the frequency converter continues until the intermediate circuit
voltage drops below the minimum stop level, which corresponds typically to 15% below the lowest rated supply
voltage of the frequency converter. Power-up and full torque cannot be expected at mains voltage lower than 10%
below the lowest rated supply voltage of the frequency converter.

Max. imbalance temporary between mains phases
True Power Factor (λ)

Environment according to EN 60664-1
The unit is suitable for use on a circuit capable of delivering not more than
•
100,000 RMS symmetrical Amperes, 480 V maximum, with fuses used as branch circuit protection
•
10,000 RMS symmetrical Amperes, 480 V maximum, with circuit breakers used as branch circuit protection

7.4 Protection and Features

Protection and features
•
Electronic thermal motor protection against overload.
•
Temperature monitoring of the heat sink ensures that the frequency converter trips when the temperature reaches
90 °C ±5°C. An overload temperature cannot be reset until the temperature of the heatsink is below 70 °C ±5 °C
(Guideline - these temperatures may vary for different power sizes, enclosures etc.). The frequency converter auto
derating function ensures that the heatsink temperature does not reach 90 °C.
•
The frequency converter is protected against short-circuits between motor terminals U, V, W.
•
When a motor phase is missing, the frequency converter trips and issues an alarm.
•
When 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, when the intermediate
circuit voltage is too low or too high.
•
The frequency converter is protected against earth faults on motor terminals U, V, W.
•
All control terminals and relay terminals 01-03/04-06 comply with PELV (Protective Extra Low Voltage). However
this does not apply to grounded Delta leg above 400 V.
