Notes for Electrical Rating Tables
Read these notes in conjunction with the following Electrical Rating tables.
1. IMPORTANT : 3% line impedance MUST be provided
for each unit, and is assumed in the quoted input current
values. Failure to do so will severely shorten DC link
capacitor lifetime and could result in damage to the
inverter. Refer to AC Line Choke table.
2. Input currents for kW ratings are at 400V 50Hz ac input,
and for Hp ratings at 460V 60Hz ac input.
3. Short circuit protection Semiconductor Fuses should be
installed in the 3-phase supply to the drive module to
protect the input bridge. Circuit breakers or HRC fuses
will not protect the input bridge.
890SD (Standalone) Drive: Frame G, H & J
4. Fundamental Input Power Factor : 0.95
5. Output Voltage (maximum) = Input Voltage
6. Output Frequency : 0 to 120Hz
7. Fan Inlet Temperature Range : 0 to 40C
8. Earth Leakage Current : >>100mA. Product must be
permanently earthed.
9. True value given, note that the MMI will display 3kHz
