Operating the UPS

Operation Modes

AC Input Mode (normal operation)

The following illustration shows circuit power flow

when the UPS is operating normally in the ac input mode. The UPS rectifier, including a
boost chopper circuit, converts ac input power to dc power. The boost chopper circuit
maintains a constant voltage, with current limiting, for charging the batteries. It also
supplies a dc voltage of the proper level to the inverter section. The inverter section
generates a high quality sine wave output voltage. The unit's batteries are always
maintained in a constantly charged state when the UPS is in the normal operation mode.

Circuit-bypass Mode

If the UPS unit is severely overloaded or develops an internal fault, power flow is
Automatically switched from the unit's main circuit to the bypass circuit. Power flow
through the bypass is shown in the following illustration. This change-over occurs
automatically in less than 4 milliseconds in phase. The switching period is not long
enough to cause interruptions to occur in most loads. If the power flow is transferred to
the bypass circuit because of an overload and that overload condition ends within a
specified period of time then the power flow will be transferred back to the AC input
mode (normal operation) automatically.

If the power flow is transferred to the

bypass circuit due to an external fault the UPS will shut down power through the
bypass to the load and indicate a system fault message. If the power flow is
transferred to the bypass circuit due to an internal fault the UPS will continue to
supply power to the load through the bypass and indicate a system fault
message

(see system fault message DC-OC on page 43).

If the power flow is

transferred to the bypass circuit due to an overload condition

(see system warning

message OL: REDUCE LOAD on page 36 and AUTO RETRANSFER on page 40)

,

then the power flow will automatically transfer from the UPS's bypass circuit
back to the inverter circuit after removing the overload if set to do so

(see auto-

transfer setting on page 34).
