Conergy IPG series central inverters
Damage due to loose screw connections!
If the securing nuts are not tightened to the specified torques, the
screws may become loose as a consequence of the vibration
produced by the terminal blocks.
Loosened screw connections change the resistance and the
conductivity at the connection. Operation of the central inverter
can be adversely affected and it may suffer damage.
| Before commissioning, check that all screw connections are
tightened to the correct torque and retighten where necessary.
