8.4 EPO (EMERGENCY POWER OFF)

All the devices in the PROTECT C 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. 24 no. 6).

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 a closer contact rather than an opener contact, go to

“Settings” in the main menu and set “REPO 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.
