battery connection terminals of the UPS system. See
and the external battery cabinet's documentation for terminal
block diagrams. See
Section 6-4

for cable size requirements. Cabling should be protected by
flexible conduit and routed through the appropriate knockouts in
5
the terminal block cover. Warning: Observe proper polarity by
connecting negative to negative, positive to positive and center
point of the battery string to normal "N". Failure to observe
proper polarity will damage the UPS system and create a risk
of personal injury and property damage.
