INSTRUCTIONS FOR SWITCHING SYSTEM IN POWER SAVE MODE TO MANUAL BYPASS MODE 

 

If for maintenance purposes or other reasons the UPS must be excluded from the system, providing at the 
same time mains power to the critical load, proceed as follows:  
 

1. Turn off the inverter  

Using menu 

1. CONTROL MODE 

select 

Inverter ON/OFF

 

and press ENTER

 

 

This turns off the inverter and uninterrupted supply is no longer guaranteed to the load 

 

2. Close MANUAL BY-PASS (I3) switch  

Remove the padlock (or any other mechanical safety lock) from the switch and lift the knob to ON 
position 

 

3. Open the INPUT MAINS (I1) switch 

 

4. Open the INPUT RESERVE (l2) switch 

The load is supplied directly from the mains through the manual By-Pass 

 

5. Open UPS OUTPUT (I4) switch 

 

6. Disconnect the battery 

 
 

 

At this point the load is supplied directly by the reserve network 

and inside the UPS there are not hazardous voltages, except of the compartment 

(covered with metal panel) where the input and output cables are connected, 

 and - for few minutes - inverter DC and AC capacitors (also covered with metal panel).
