If you are installing a customer-supplied battery system, install the battery system
according to the battery and battery system manufacturer’s instructions and all
the applicable national codes and regulations. Only qualified personnel may
install the battery system. Battery cables must be protected against current and
thermal overload, that is, the battery system must include proper fuses or breaker
with protection function. Ground the external battery cabinet to the UPS.
The default battery settings of the UPS are for 12 V VRLA batteries. If you need
to use any other type of batteries, contact your Eaton representative.
5.3.1 Battery trip wiring
The external battery breakers can be tripped (switched off) by energizing its
shunt trip coil. The shunt trip coils are energized (controlled) through connector
X8. The status signal of the external battery breaker is also connected to
connector X8. Status contacts of the Eaton battery breakers are open if the
breaker itself is open.
NOTE: The default voltage of the battery breaker shunt trip coil is 24 Vdc.
