the power supply of the loads. In this configuration, the system
can be restarted by means of the return from load procedure in
the manual bypass, avoiding leaving the loads without voltage.
Manual bypass.
To perform the switching procedure correctly, verify that
there are no alarms present in the system.
While the device is in manual bypass, the load is powered
directly by the input mains, so continuous powering of the loads
cannot be guaranteed.

LED 6 is shown in orange. The screen indicates alarm A30
(common alarm).
