2. Install the ELS2-ACW mains cutoff unit(s) in system cabinet(s)
(metal back panel, lower right-hand corner): position the device
(note right/left) with the brackets in the middle lower row of
square holes and lightly press the sides until it engages in the
ridges.
3. Connect the output socket(s) of the mains cutoff unit(s) and
PSUI(s) using the cable(s) supplied (Figure 6-2, [A]). Secure each
PSUI interface with two screws.
4. Connect PSUI(s) and battery managers using the cable(s)
supplied (Figure 6-2). Cables must be routed to the cabinet(s)
from the rear and mounted on the metal back panel.
5. Insert power cable (Figure 6-2, [C]) in the upper input socket(s)
of the network splitting device(s).

5. Connect the connecting cable between the external
battery/charging rectifier and the distribution frame.
Caution! Connecting lines must be protected (max. 25 A)!
6. Insert power cable (Figure 6-2, [C]) in the upper input socket(s)
