If 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. For the battery specification, refer to the Eaton 91PS/93PS 8-10
kW UPS User's and Installation Guide.
The 91PS/93PS 8-10 kW UPS units are always equipped with an internal battery breaker,
which affects only the UPS internal batteries. The external battery breaker is a crucial part
of the external battery cabinet or rack and must be placed in it. With the external battery
breaker, signal cabling is important.
Both internal and external battery breakers can be tripped (switched off) by energizing its
shunt trip coil. The shunt trip coils of external battery breakers are energized (controlled)
through connector TB20. The default voltage of the shunt trip coil is 24 Vdc.
Battery trip wiring is shown in illustration 8. The parts are as follows:
A External battery breaker
1 Pin 1, shunt trip coil +
2 Pin 2, shunt trip coil -
For instructions on how to install the external battery cabinet and battery power cabling,
see the Eaton 91PS/93PS 8-10 kW User's and Installation Guide and the instruction
