Boards for HiPath 3000
Central Board
– Off = At least one secondary operating voltage is outside the tolerance zone. In this
case
a) the voltage feed for LUNA2 may not be sufficient (an additional LUNA2 module is
required. For information on how to calculate the number of LUNA2 modules required,
see Page 3-61.).
b) LUNA2 may be defective (the board must be replaced).
ON/OFF switch for secondary operating voltages (system supply voltages)
●
Caution
7
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 (forexample, 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.
Switches for setting the operating mode (the operating mode must be set before the outer
●
panel is mounted):
– Mode 1: For use as power supply (LED illuminated)
– Mode 2a: For use as battery charger (LED flashing) with a charging voltage of 54.7
VDC
– Mode 2b: For use as battery charger (LED flashing) with a charging voltage of
53.5 VDC
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 system 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", the only power supplies that should be
●
plugged in are those
