Alarm Connections 

Eight alarm relays (and 10 alarm LEDs) are included on the rectifier section as a standard feature of the AUPS. 

The  included  alarms  are  Low  DC  Current,  Low  DC  Voltage,  High  DC  Voltage,  High  Voltage  Shutdown,  AC 
Failure, Negative Ground Detection, Positive Ground Detection, and Summary. 
Five status indicator relays (and 11 status LEDs) are included on the inverter section as a standard feature of 
the  AUPS.  The  included  status  indicators  are  Phase  Locked,  Utility  Available,  Inverter  Available,  Load  on 
Preferred Source, and Load on Alternate Source.   
Each alarm/status indicator relay includes two sets of form 

C

 contacts, enabling the user to connect multiple 

remote annunciators. Refer to Figure 5 and 6 for contact connections. 

 
 

 
 

 

 
 

 
 

 
 

 

 

Alarm  LEDs  are  provided  on  the  rectifier  section  for  the  following  alarms:  AC  Fail,  Low  DC  Voltage,  End  of 

Discharge, High DC Voltage, High Voltage Shutdown, Low DC Current, Overload/Current Limit, Positive Ground, 
Negative Ground, and Summary. Refer to Figure 7 below. 

If an alarm condition occurs for a default time of longer than 5 seconds, the Summary alarm relay will activate if 
the corresponding alarm is included in the Summary alarm. The HVSD alarm is default set to trigger after 20 

seconds.  When  an  alarm  activates,  the  specific  indicator  on  the  front  panel  will  light,  any  connected  remote 
annunciators will activate, and the display will cycle through all active alarms.
