ELECTRICAL CONNECTIONS
SOFAR 1100...3300TL-G3 33
5 Electrical connections
5.1 Safety instructions
This topic describes the electrical connections of the inverter SOFAR
1100TL ... 3300TL-G3. Read this section thoroughly and carefully
before connecting the cables.
Electrical voltage at the DC connections
• Ensure that the DC switch is OFF before establishing the
electrical connection. The reason is that the electrical charge
remains in the capacitor after the DC switch has been
switched off. Therefore, at least 5 minutes must lapse before
the capacitor has been electrically discharged.
Electrical voltage
• PV modules generate electrical energy when exposed to
sunlight, and this may present an electrical shock hazard.
Therefore, cover the PV modules with an opaque sheet
before connecting to the DC input power cable.
Qualification
• The installation and maintenance of the inverter must be
carried out by an electrician.
