4.8. INSTRUCTIONS FOR RETURN FROM MANUAL BY-PASS MODE TO NORMAL OPERATION
1. Close the INPUT RESERVE (l2) switch
UPS will begin normal operation.
If the reserve line voltage parameters are correct, the UPS fans will switch on.
On the control panel the red indicator will appear.
2. Close the UPS OUTPUT (l4) switch
On the control panel the red indicator remains on.
3. Open MANUAL BY-PASS (l3) switch
Since this moment load will be supplied from the reserve line.
Mount the padlock on the manual by-pass switch (l3).
On the control panel the red indicator remains on.
4. Close the MAINS INPUT (l1) switch
After few seconds the start-up procedure will be started. Depending of the UPS start-up configuration
setting, refer to one of the following sections:
- see section 4.4 for “AUTOMATIC” Start-up mode: steps 3 - 4
- see section 4.5 for “NORMAL” Start-up mode: steps 3 - 4 - 5
4.9. E.P.O. (EMERGENCY POWER OFF) STOP
The purpose of the emergency stop is to completely shut down the UPS if necessary, with the resulting
instant switch off the static switch from both reserve and inverter sources. This eliminates any power
presence at the UPS output and - in consequence - at the load.
Obviously, hazardous voltages remain inside the UPS panel.
To reset EPO mode, the complete UPS shut down procedure is required.
