9 System Decommissioning/Shutdown Procedure 9.1 Decommissioning the Inverter 9.1.1 Disconnecting the Inverter CAUTION Danger of burns! Even if the inverter is shut down, it may still be hot and cause burns. Wear protective gloves before operating the inverter after it cools down. For maintenance or other service work, the inverter must be switched off.
9 System Decommissioning/Shutdown Procedure User Manual Before dismantling the inverter, disconnect both AC and DC connections. If there are more than two layers of inverter DC terminals, dismantle the outer DC connectors before dismantling the inner ones. If the original packing materials are available, put the inverter inside them and then seal them using adhesive tape.
