INSTRUCTIONS FOR COMPLETELY SHUTTING OFF THE UPS IN POWER SAVE MODE
If for maintenance or other reasons you want to completely shut off the system and leave the uses not fed
proceed as follows:
1. Turn off the inverter
Using menu 3. CONTROL MODE select Inverter ON\OFF and press ENTER
This turns off the inverter and uninterrupted supply to the uses is no longer guaranteed
2. Open LOAD l3 circuit breaker
In this situation the loads are not fed
3. Open the RESERVE INPUT l2 circuit breaker.
4. Open the MAINS l2 circuit breaker.
5. 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).
