The SureWave SFC provides information including input/output voltages/frequencies/currents,
and system status through the Modbus TCP communication port.

Auxiliary AC power supply for LV PSU
The SureWave SFC’s LV PSU can be externally feed if required from a 3-phase, 3-wire AC voltage
(380 V to 480 V). The terminal locations are depending on the SFC model.
9.3.1 250 kVA to 750 kVA models
For SureWave SFC models between 250 kVA and 750 kVA the 3-phase terminals location is on the
peripheral tray, in the bottom right corner of the PE120-U1 enclosure (when view from the front).
