Procedure:
1.
Danger to life due to high voltages
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 no voltage is present on the input strings.
• Ensure that the Rapid Shutdown Box is closed.
2. Connect the input strings to the MC4 connectors
that lead from the Rapid Shutdown Box. When
doing so, ensure that the positive terminal and
negative terminal have the correct polarity.
☑ The connectors snap audibly into place.
3.
Damage to the MC4 connectors due to moisture ingress.
The MC4 connectors are only sealed if all MC4 connectors leading from the Rapid
Shutdown Box that are not required are sealed using the supplied sealing plugs.
• Plug the supplied sealing plugs into the MC4 connectors that are not required.
