2.3.2 Battery system installation
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 93PS UPS 8-40 kW User’s and Installation
Guide.
2.3.3 Battery trip wiring
The 93PS 8-40 kW UPS units are always equipped with an internal battery breaker, which
affects only the UPS internal batteries (except for the C model, where the internal battery
breaker can be used for external 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 connectors TB20 and TB21 (TB21 available only in the 30-40 kW UPS with
separate battery configuration). The default voltage of the shunt trip coil is 24 Vdc.
Battery trip wiring is shown in illustration 9. The parts are as follows:
