Specifications

6.3 Mains Supply

Mains supply (L1, L2, L3)
Supply voltage
Mains voltage low/mains dropout:
•
During low mains voltage or a mains dropout, the frequency converter continues until the DC-link voltage drops below
the minimum stop level. This level typically corresponds 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.
Supply frequency
Maximum imbalance temporary between mains phases
True power factor (λ)
Displacement power factor (COSφ)
Switching on the input supply L1, L2, L3 (power-ups)
Environment according to EN 60664-1 and IEC 61800-5-1
The unit is suitable for use on a circuit capable of delivering not more than:
•
100000 RMS symmetrical Amperes, 480 V maximum, with fuses used as branch circuit protection.
•
See Table 6.14 and Table 6.15 when using circuit breakers as branch circuit protection.

6.4 Protection and Features

Protection and features
•
Electronic motor thermal protection against overload.
•
Temperature monitoring of the heat sink ensures that the frequency converter trips when the temperature reaches
90 °C (194 °F) ±5 °C (41 °F). An overload temperature cannot be reset until the temperature of the heat sink is
below 70 °C (158 °F) ±5 °C (41 °F). However, these temperatures may vary for different power sizes, enclosures,
and so on. The frequency converter autoderating function ensures that the heat sink temperature does not reach
90 °C (194 °F).
•
The frequency converter motor terminals U, V, and W are protected against ground faults at power-up and start of
the motor.
•
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 DC-link voltage ensures that the frequency converter trips when the DC-link voltage is too low
or too high.
•
The frequency converter is protected against ground faults on motor terminals U, V, and W.
•
All control terminals and relay terminals 01–03/04–06 comply with PELV (protective extra low voltage). However,
this compliance does not apply to grounded delta leg above 300 V.
