10 Recommissioning the Inverter
If you have disconnected the inverter from voltage sources (e.g. for configuration purposes) and want
to re-commission it, proceed as follows.
Requirements:
☐ The AC miniature circuit-breaker must be correctly rated.
☐ A rectifier and overvoltage protection must be installed between the inverter and the plant.
☐ The inverter must be correctly mounted.
1. Connect the rectifier to the inverter:
• Connect the positive connection cable to the
front positive DC connector of input A on the
inverter.
• Connect the negative connection cable to the
front negative DC connector of input A on the
inverter.
☑ The DC connectors click audibly into place.
2. Seal all unused DC inputs using the DC connectors
with sealing plugs.
