Commissioning an EBL128
Before you connect any power to EBL128 all other cable connections
shall be made. Check, once more, that the connections are correct.
1.
Remove the rectifier (power supply) fuse (F1) and the battery fuse
(F2) on the main board (or the fuse between the batteries).
2.
Connect the batteries to the main board.
3.
Connect the rectifier to the mains (230 V AC).
4.
Put back the rectifier fuse (F1) on the main board.

5.
Put back the battery fuse.
6.
LED "Operation" (L6) indicates that the 24 V DC power supply
(rectifier and/or battery) is okay.
7.
An automatic restart will now take place (see chapter "Restart",
page 74.
8.
The site specific data (SSD) is now to be downloaded, see chapter
"SSD programming & download", page 69.

Regarding especially the previous main board 4556 version (P.c.b.
No. 9285-
5
A): If a lot of units (especially units with high internal
capacitance) are connected to EBL128, the total momentary inrush
current consumption for these units might be too high for the power
supply's electronic short circuit protection and EBL128 will not start
working properly. In such a case, put back the battery fuse before the
rectifier fuse (i.e. the batteries have to be reasonably charged) or
temporarily disconnect some of the units in order to reduce the current
consumption while EBL128 is powered.
