* BATTERY TYPE DESIGNATIONS: B = C&D, H = HAWKER
NOTE:
The term “Separate” refers to battery cabinets that are not physically attached to the
UPS, are wired with external contractor supplied wiring, and use a single overcurent
protection and disconnect device located near the batteries.
The term “Integral” refers to battery cabinets that are physically attached to the UPS
and the wiring between them is internal. The power wiring is supplied with the
system, and they use the UPS battery switch as the battery isolation device.
The wire size rating for products up to and including the 160/160 are for the total
battery supply. Since these UPS units can only land one wire per DC connection
point, a common DC collector including an isolation device and overcurrent
protection should be used. Refer to applicable national or local code requirements
for your installation.
