ENGLISH
For safety reasons, the equipment must always possess an earth connection, which in any case must also be the last connection
to be disconnected.
4. WIRING
WARNING!
The inverter must only be connected to the mains electricity network by qualified operators after the appliance has
been securely fixed to the wall.
Before carrying out any electrical connection or system maintenance procedures, the following checks must be
performed:
• Make sure that both disconnection switches (DC and AC) are open (OFF).
• Make sure the photovoltaic system cannot be restarted.
• Cover the panels with radiation blocking material (preferably black in colour).
• Make sure there is not electrical voltage being supplied from the mains network or the photovoltaic field.
Any non-conforming procedure could place the operator in a hazardous situation and may damage the equipment.
WARNING!
Always observe the rated voltage and current values specified in the design phase of your system. It is especially impor-
tant to observe the maximum voltage and current values for the photovoltaic field (see "Technical data" chapter).
4.1. Earth wire connection
DANGER!
Risk of electric shocks from live device parts!
The inverter can be connected to two separate power sources:
• DC cable – Power from the photovoltaic generator
• AC cable – Power from the mains network, supplied by the electricity company
Before carrying out any work, make sure the electricity sources have been disconnected.
Before connecting to the mains network and photovoltaic field, the inverter should be earthed using the connection point on the
casing. The wire must have a cross-section which is at least equal to that of the phase wire in order to guarantee optimal conductivity.
Correct connection is illustrated in figure 4.1-1.
