6.3 Mains Supply
Mains supply (L1, L2, L3)
Supply voltage
380–480 V
±
10%
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.

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.
•

and
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.
