All the devices in the PROTECT D. series are equipped with a 
connection that allows the immediate shutdown of the UPS 
output to deactivate any devices connected and does not follow 
the control software shutdown process.

Note:  
Once the emergency power off has been 
activated, the UPS outputs are voltage-free. The 
UPS will not return to normal operation until the 
emergency power off has been confirmed/reset 
and a manual reboot performed by activating the 
“UPS On” switch once again. 

To install the Emergency Power Off, proceed as follows:  

1. 

Check to see that the UPS is switched off and switch 
it off if necessary. 

2. 

Remove the plug from the EPO insert on the rear 
panel of the UPS by unscrewing the 2 outer screws 
(also see pg. 31 no. 7). 

3.  Connect a potential-free opener contact (able to 

manage a load of at least 60 Vdc/ 30 Vac 20 mA) 
with the pins of the plug. 

4. 

To do so, use a flexible wire with a diameter of min. 
0.5 mm

 or max. 2.5 mm

. Replace the plug and lock 

the insert into place in the base by tightening the 
outer screws.

Note:  
If you want to use an open contact 
rather than a closed contact, go to 
“Settings” in the main menu and set 
“EPO operation” to “normally open”. 

 

The Emergency Power Off installed only switches off
the UPS voltage. This is done electronically and is 
not the same as an EMERGENCY STOP system
corresponding to DIN EN ISO 13850.
