7.2

Decommissioning the power supply unit for storage purposes

If the power supply unit is not going to be used for some time, the power supply
unit batteries must be fully charged first to prevent self-discharge causing dama-
ge to them.
Before decommissioning:
1. To charge the batteries, connect the power supply unit to the input voltage
(115 – 230 V) at least 4 hours before decommissioning.
2. Revoke the UPS function enabling (remove the insertion bridge (3); otherwi-
se, the load will continue to be supplied by the batteries until the deep
discharge protection disconnection function is activated.
3. Disconnect the power supply unit UPS from the mains.
If the batteries are being stored for an extended period, they must be recharged
every 6 months.
