6 Electrical Connection
☐ Qty single wires: minimum 7
☐ Nominal voltage: minimum 1000 V
☐ Using bootlace ferrules is not allowed.
Danger to life due to high voltages on the DC conductors
When exposed to sunlight, the PV array generates dangerous DC voltage which is present in the
DC conductors. Touching the DC conductors can lead to lethal electric shocks.
• Ensure that the inverter is disconnected from all voltage sources.
• Do not touch non-insulated cable ends.
• Do not touch the DC conductors.
Destruction of the inverter due to overvoltage
If the open-circuit voltage of the PV modules exceeds the maximum input voltage of the inverter,
the inverter can be destroyed due to overvoltage.
• If the open-circuit voltage of the PV modules exceeds the maximum input voltage of the
inverter, do not connect any strings to the inverter and check the design of the PV system.
Procedure:
1. Strip 12 mm of the cable insulation.
2. Insert the stripped cable into the DC connector up to
the stop. When doing so, ensure that the stripped
cable and the DC connector are of the same
polarity.
3. Press the clamping bracket down until it audibly
snaps into place.
