Installing batteries in the auxiliary equipment housing
Introduction to
battery
installation
The auxiliary equipment housing can be fitted with two banks of eight 6 V
batteries, mounted on four battery trays. Each bank is wired together in series to
provide –48 V dc backup power for the Horizon
macro outdoor cabinet. The two
banks can be wired in parallel, to provide increased backup duration for a single
BTS cabinet, or fed separately to two BTS cabinets.
NOTE
Batteries must be fully charged and load tested before
installation.
