Decommissioning

7.1

Temporarily switching off the uninterruptible power supply

2. Revoke the UPS function enabling (remove the insertable jumper(3)); other-
wise, the load will continue to be supplied by the batteries until the total
discharge protection disconnection function is activated.
7.2

Decommissioning the uninterruptable power supply for storage purposes

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