12.5.2 Battery Charging
The UPS Solution offers temperature compensated battery charging to help keep all
battery packs in optimum condition across its extended operating ambient temperature
range. The battery charging voltage is adjusted by -5.0mV/°C/cell.
12.5.3 Battery Support Hold Up Times
Ambient temperature plays a big part in determining how much a battery support hold up
time is available. As temperature decreases, the available capacity of each battery pack
is reduced as battery chemistry becomes increasingly inert. This becomes very apparent
and extremely low ambient temperatures.
APPENDIX A – Estimated Hold Up Times shows battery hold up runtime charts (such as
in section 5) adjusted for ambient cabinet temperatures of +20°C, 0°C and -25°C.

12.6.1 The Generator Connect Feeder Pillar
As stated in section 2.4, a diesel generator must be connected via the Siemens
