8.3. Emergency Switching Device and Generator Connections 

Voltage to be applied to the digital inputs is 5VDC. Maximum current drawn by each input is 1mA. 5VDC supply 
provided on the communication interface board can be used to supply both digital inputs.  
 

 

 
 

 

 
 
 
 
 
 
 
UPS output can be switched  off immediately by Remote Emergency Switching Device interface (ESD)  connection if 
desired. A remote latched switch can be used as described in above figure.  
 

Input 

Function 

UPS OFF 

If the UPS OFF input is set high by applying 5VDC voltage on the related terminals, UPS stops 
generating the output voltage and stops feeding the load. When the voltage on the digital 
input is removed, you have to restart UPS. 

The factory default setting of ESD contact is 

“Normally open”.

 

GEN ON 

If the GEN ON input is set high by applying 5VDC voltage on the related terminals, UPS 
transfers to Generator Mode, bypass and battery charging is disabled. Generator icon appears 
on Energy Flow Diagram screen. 

The factory default setting of Generator contact is “Normally 

open”.

 

Tablo.9

 

 

 

 

 

 

Pay attention to the polarity of the voltages applied to the digital input terminals.
