So, i have the Profilux 3EX with 2 powerbars 6D currently connected. I have 1 powerbar connected to an inverter powers source in case of power failure. What i would like to know, is if there is ever a power outage, i would like say 3 plugs to be running even though the profilux is offline. This will leave my return line and 2 power heads running till power is restored. Is this possible? The rest of the system can be offline.
