Guide Specification – 3-Phase Static Uninterruptible Power Supply 
 

12 

 

If the bypass source is beyond the conditions stated below, interrupted transfer shall be 
made upon detection of a fault condition. 

  Bypass voltage greater than + 10%, -10% from the UPS rated output voltage. 
  Bypass frequency greater than + 1 Hz from the UPS rated output frequency. 

 

5.4.2  Overload Capacity in Bypass: 

  Continuous duty 

 

: 125% of the system rated capacity 

  Overload duty  

 

: 1000% of ampere rating for 1 cycle. 

 

5.4.3  Retry function:  

When an internal warning has been detected, power flow will automatically switch from 
the main circuit (inverter) to the bypass circuit without interruption to the load. If the 
internal warning is cleared, UPS will automatically switch the power flow from the 
bypass circuit to the main circuit (inverter) without interruption. 

 

5.5  Metering, Monitoring, Alarms, and Controls 

 
5.5.1  Status Indicators 

The Front Panel shall include LED status indicators for the following states: 

Load on Inverter 
Battery Operation 
Load on Bypass 
Overload 
LCD Fault 
UPS Fault 

 
5.5.2  EPO (Emergency Power Off) Button 

The Front Panel shall have an Emergency Power Off  button (EPO) located on the front 
panel that, when pressed, will shut down the UPS.  

 
5.5.3  Liquid Crystal Display (LCD) Touch Panel 

The Front Panel shall include a LCD touch panel that shall provide performance data, 
statistics, and operating conditions. The following metering will be displayed on LCD 
touch panel: 

AC Input Voltage  
AC Input Frequency  
AC Output Voltage
