2.3 Preliminaries
Before installing the ONLITE central CPS system, open the following fuses:
•
Main fuses: -2F1, -2F2, -2F10.2 and -2F10.2
•
Battery fuses: -2F4, -2F5, -2F6 and -2F7
•
Outgoing fuses in the individual sub distributions: F1 to F20, both for phase L (red labelled
fuses) and for the neutral wire N (blue labelled fuse).
If the battery case (ONLITE central CPS K) or the battery cabinets (ONLITE central CPS H)
contain any batteries, you have to remove them prior to installation. In this case, also note the
instructions described in chapter "Handling instructions for sealed vent-regulated lead acid
batteries" (see chap. C on page 31).

Already installed and connected batteries must be removed taking into account the
battery installation order.
