8.4EPO (Emergency Power Off)

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 mm2 or max. 2.5 mm2. Replace the plug and lock the insert into place in the base by tightening the outer screws.

Note:

i 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.
