7.2.2.1 Before connecting
Ensure that there is no ground fault
1. Determine the DC voltage between the
– protective earth (PE) and the positive cable of the PV generator, and between the
– protective earth (PE) and the negative cable of the PV generator.
If stable voltages can be measured, there is a ground fault in the DC generator or its wiring. The ratio between the
measured voltages gives an indication as to the location of this fault.
2. Rectify any faults before taking further measurements.
3. Determine the electrical resistance between the
– protective earth (PE) and the positive cable of the PV generator, and between the
– protective earth (PE) and the negative cable of the PV generator.
4. Rectify any faults before connecting the DC generator.
7.2.2.2 Connecting the PV generator
Risk of fatal injury due to electric shock
Severe injury or death will result if the live connections are touched. When there is sunlight present
on the photovoltaic modules, there is DC voltage on the open ends of the DC cables.
