DC to DC Converter

The DC to DC converter utilizes energy from the battery system and raises the DC voltage to the
optimum operating voltage for the inverter. This allows the inverter to operate continuously at its
optimum efficiency and voltage, thus increasing reliability.
3.6

Battery

The 10Kva RT utilizes valve-regulated, nonspillable, flame retardant, lead acid
batteries. To maintain battery design life, operate the UPS in an ambient temperature of 68°F to 77°F
(20°C to 25°C). Optional external battery cabinets are available to extend battery run times.
3.7

Static Bypass

The 10Kva RT provides an alternate path for utility power to the connected load
in the unlikely event of a UPS malfunction. Should the UPS have an overload, overtemperature or
UPS failure condition, the UPS automatically transfers the connected load to bypass. Bypass
operation is indicated by an audible alarm and illuminated amber Bypass indicator (other indicators may
be illuminated to indicate the diagnosed problem).
The user may manually transfer the connected load from the inverter to bypass by pressing the
Standby button once.
NOTE
The bypass power path does NOT protect the connected equipment from disturbances
on the utility supply.
