B) Internal Static Bypass Line (FIGURE 1.2)
The Internal Static Bypass line is a Hard wired line through CB3, contactor 52S which
supplies the critical load with unconditioned input power. The purpose of this line is to
route power to the critical load while the UPS module is de-energized during Start-up
before the system is fully operational.

If the input power is interrupted, the battery will immediately supply the DC power required
by the Inverter to maintain continuous AC power to the load. A fully charged battery will
provide power for the specified time at the rated load, or longer, at a reduced load.
