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.
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.
