INSTALLATION
DANGER
Always remove voltage before operating on the grid. The ground conductor must be connected first.
CAUTION
Follow the sequence below to carry out the electrical connection of the SUNWAY M XS:
1. Carry out the ground connection of the inverter;
2. Carry out the electrical connection to the grid;
3. Carry out the electrical connection of the inverter to the photovoltaic field.
RESIDUAL CURRENT DEVICE – A residual current device is integrated into the Sunway M XS. The RCD provides
protection against residual DC and AC currents and is compliant with the safety regulations in force. The efficiency of the
RCD is checked when testing the inverter and whenever the inverter is connected to the grid. The integrated RCD
provides protection against DC-side faults only. As per AC-side protection, an external RCD of type A is to be provided to
protect the line between the inverter and the delivery point.
MOULDED CASE CIRCUIT BREAKER – Always install a MCCB to protect the electric circuit.
Carry out the ground connection of the inverter before carrying out any electrical connection. The SUNWAY M XS is
supplied with a three-wire cable for the connection to the grid. First connect the yellow-green wire to the ground of the
electrical system external to the inverter. The yellow-green wire is internally connected to the Protective Earth of the
circuit. Please consult the Installation and Programming Guide for any details on how to assemble the quick connectors
for the connection to the PV field.
The Sunway M XS inverters are supplied from the grid. Once the connection to the grid is complete, press the WAKE UP
button to start up the inverter.
If the DC disconnect switch (optional) is installed, it must be set to ON.
Carry out the quick configuration procedure from the Settings menu by pressing the icon here below. The quick
configuration procedure makes it possible to change the grid interface settings as well. Note that the grid interface
configuration may be changed only within the first 12 hours after the commissioning of the inverter.
When the quick configuration procedure is complete, press START to start up the inverter.
The inverter checks if the field voltage is higher than the value set in P020 (factory setting: 370V) and waits for the
timeout in P021 (factory-setting: 5 minutes) before connecting in parallel with the grid and start delivering power.
CAUTION
GRID INTERFACE CONFIGURATION – The grid interface configuration based on the Country where the inverter is
installed may be changed only within the first 12 hours after the commissioning of the inverter.
PASSWORD FORM – The password required to access the inverter data is given in a special form supplied with the
SUNWAY M XS inverter. Please consult the Installation and Programming Guide for any details about the inverter
functionality.
