10.3 Battery Backup (On batteries)

The following illustration shows power flow during the battery backup mode. When commercial AC power failures occur, the UPS’s batteries instantly begin supplying DC voltage to the UPS’s main inverter circuit. This circuit changes (inverts) the DC power into AC power. The AC power is available at the output of the unit.

This back-up process will continue until the UPS’s battery voltage drops below a specific minimum level. When this occurs, the batteries will stop supplying power to the load. This minimum level is the rated minimum voltage (Vmin). The rated battery voltage chart on page 19 shows (Vmin). The battery backup time and discharge process is explained on page 19.

10.4 EPO (Emergency Power Off) Function

These units are equipped with terminals for receiving an emergency power-off (EPO) command via a closed-contact switch at a remote location (see Terminal Block Details on page 11 and terminal block location on pages 60-61). This safety feature enables quick shut-down of the UPS’s AC input breaker, output and battery circuits.

Usually the emergency power off switch is installed in a central location that is easily accessible to personnel concerned with the operation of the UPS unit and the load equipment connected to it. The EPO function is initiated by pressing the switch to the closed (shutdown) position.

The effect of using the EPO switch is the same whether the UPS unit is in AC input mode, battery backup mode, or the circuit bypass mode. The following figure shows the UPS condition after application of the EPO switch.
