Additional single feed kits are available for the 93PS (3-phase in / 3-phase out) and 91PS
1:1 (1-phase in / 1-phase out) units. Single feed kit installation for 93PS (3:3) is described
in illustration 11. For 91PS (1:1) it is described in illustration 12. Single feed kits are
included in the UPS package. Make sure that you press the single feed kits to the bottom.
This may require some force.
Do NOT apply single feed installation to 3:1 units.
2.4.3 91PS field configuration
The field configuration of 91PS from 3:1 to 1:1 is described in illustrations 13.1 and 13.2.

2.4.4 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 91PS/93PS 8-10
kW UPS User's and Installation Guide.
2.4.5 Battery trip wiring
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 +
