9. PREVENTIVE MAINTENANCE
WARNING!
Inspection may only be carried out by the system manager, or by an authorised person.
WARNING!
In the event of a fault, the system must not be restarted. Inverter maintenance or repairs must be performed by SOCOMEC
personnel, or by personnel from a SOCOMEC authorised support centre.

DANGER!
Risk of electric shock from live device parts!
In the event of system maintenance, carry out the following steps beforehand:
• Disconnect the photovoltaic system.
• Make sure the photovoltaic system cannot be restarted.
• Make sure the mains electricity supply has been disconnected.
• Earth the device units and short-circuit them.
• Cover or separate nearby live device units.
• Before working on the circuits upstream make sure the inverter is disconnected by opening
the DC disconnection switches.
DANGER!
Risk of electric shock from live device parts!
The inverter can be connected to a maximum of three power supplies:
1 DC cable - Photovoltaic generator power supply (separated for the three modules or shared)
2 AC cable - Power from the mains network, supplied by the electricity company
3 AC cable - Auxiliary power supply
• Before carrying out any work, make sure the electricity supply has been disconnected.
• All DC power supplies should be considered as part of the same circuit, even in the configuration with centralised multi-
string inverter. Before carrying out any work, make sure all electricity supplies have been disconnected.
DANGER!
Risk of electric shock from live device parts!
The intermediate inverter circuit may be live even after it has been deactivated.
• Wait for the power to disperse and make sure that there is none remaining.
DANGER!
Risk of electric shock from live device parts!
The photovoltaic modules are live as soon as they are exposed to sunlight.
• Take suitable measures and make sure there is no power remaining.
