4.4 Making changes to the system

Master and slave(s) are identical inverters. Their function in the system is deter-
mined by the connection to the parallel box:
Master: data input (2) and power input (3)
Slave(s): data inputs (9, 10, 11) and power inputs (6, 7, 8)
WARNING
Danger of explosion from sparking! Danger of electric shock!
Plugs and cables must not be disconnected when voltage is present!
Before pulling out plugs or disconnecting cables make sure that no loads are
X
connected and the inverters are disconnected from the battery.
The cables pre-fitted to the inverters must not be extended.
X
4.4.1 Replacing inverters
Proceed as follows when replacing the master or a slave:
Make sure that no loads are connected and the inverters are disconnected
X
from the battery.
Pull out the RJ45 plug at the relevant data input.
X
Open the parallel switch box.
X
Disconnect the input of the relevant master or slave at the parallel switch
X
box.
Connect the new master or slave, as described in Section 4.2.
X
4.4.2 Using a slave as the master
If the master fails, a slave can be used as the new master.
Make sure that no loads are connected and the inverters are disconnected
X
from the battery.
Pull out the RJ45 plugs of the data inputs (2) and (9, 10, 11).
X
Open the parallel switch box.
X
Disconnect all the cables at the parallel switch box.
X
Connect the reconfigurated system as described in Section 4.2.
