Bypass Input—Displays the bypass input voltage and the bypass input frequency. The bypass cir- cuit breaker (BFB) is to the right of this block. The circuit breaker status is shown as open or closed.

UPS Input Power—Displays the UPS input voltage, current and frequency. The input circuit breaker (CB1) is to the right of this block. The circuit breaker status is shown as open or closed.

Battery Block—Displays the battery voltage and the charge or discharge current to or from the bat- tery. Pressing this icon switches among the connected battery strings. The Module Battery Discon- nect (MBD) is to the right of this block. The circuit breaker status is shown as open or closed.

DC Bus—Displays the DC Bus voltage and the state of the battery charger.

Load—Displays the output line voltage, phase voltage, current, kVA, kW, power factor and fre- quency. The critical load current per phase is also displayed in this block. During an overload, the time remaining before transfer is displayed at the bottom of the load box. After an overload transfer, retransfer timeout is displayed at the bottom of the load box.
