9.2.8 Modbus TCP
Ethernet standards support different physical media and topologies. Modbus TCP is a variant
of the Modbus communication which uses Modbus messages over TCP connection in an IP net-
work.
The SureWave SFC provides information including input/output voltages/frequencies/currents,
and system status through the Modbus TCP communication port.
For a detailed description of Modbus registers, addresses and ranges, refer to SureWave SFC

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).
