Caution
The switches for deactivating the secondary operating voltage (system supply
voltage) must be set to "DC-OFF" on all LUNA2s during maintenance work that
requires the system to be de-energized (for example, central board replace-
ment). The system is only in de-energized state if the switches on ALL
LUNA2s are set to “DC-OFF” position.
The system is only restarted if all LUNA2 switches are returned to the “DC-ON”
position.
>
From a technical viewpoint, there are no differences between the LUNA2 slots.
A LUNA2 can be used in all slots, regardless of the selected operating mode.
To achieve a uniform LUNA2 configuration worldwide, the following rules should
be observed:
● The power supplies that are used to supply the system directly should be
plugged in at LUNA2 slots 1, 2, and 3 (expansion cabinet only).
● At the LUNA2 slot marked “4”, only power supplies that
– are used for LUNA2 redundancy should be plugged in (set to mode 1).
– are used as a battery charger should be plugged in (set to mode 2a or
mode 2b).
