WARNING Improper handling with batteries can be dangerous. Please read and understand
the information in the Safety chapter before connecting batteries.
CAUTION Follow closely the battery manufacturer’s specications regarding the
maximum battery charge current value. If the value is less than 5 A, Low Power Shelf
version is required.
WARNING The battery cables should be connected to the shelf as rst, then to the
batteries. If the battery cables are already connected to the batteries disconnect the -48 V
cable from the battery at least.
Battery connections are available at the rear of the system adjacent to the load connections,
see Figure 4-6.
To connect:
1. Remove sucient insulation from the
cable (max. 12mm). Make sure no single
stranded wire comes loose and touch any
other conductive wire.
2. Insert a at screwdriver into the square
opening of the battery connection to
release a spring latch.
3. Insert the stripped cable into the
appropriate round opening.
4. Connect the other end of the battery
