Replacing the Inverter
Replacing the Inverter
When replacing the Inverter, ensure that you use the correct replacement Inverter.
To replace the Inverter the following procedure should be performed:
1. Disconnect the Inverter from the power supply.
2. Wait at least 5 minutes to allow the Inverter to discharged all residual power.
3. Disconnect all cables and connections from the Inverter to be replaced.
– There is no need to remove the M12 ASi branch nodes from the ASi-bus. The
ASi-controller will recognize that the two slave nodes have been removed from the
network. This will not interrupt the communications or other devices on the ASi
network.
4. If a memory card has been used, remove it from the Inverter.
5. Remove the Inverter from its mounted position.
6. Mount the new Inverter, ensuring that if a memory card is used, it is fitted before
mounting the Inverter.
7. Reconnect all the cables and ASi connections.
8. Switch-on the power to the Inverter.
9. The ASi-controller will automatically recognize the new slave nodes and assign them an
appropriate address.
– The Inverter contains two slave nodes, one is visible to the network, the other is
hidden. When the first node is assigned an address, the second node becomes visible
to the network. The second node is then assigned an appropriate address.
10.If required, manually download a valid parameter set.
