"Monitor" alphanumeric display
The battery is currently being recharged.
The inverter frequency is stable and accurate to 0.05Hz, but no longer synchronous with that of Mains 2.
This message is valid only for parallel UPS systems. The number of UPSs ready for connection to the load is insufficient for
the required power level. Another UPS must be started before all the lines together may supply the load. Until another line is
started, the load will remain supplied by Mains 2.
Indicates that the battery has probably reached the end of its service life (based on the estimated average service life since
its installation).
Transfer of the load to Mains 2 is inhibited due to:
– certain transfer conditions not satisfied;
– "transfer to Mains 2 with interruption disabled" auxiliary contact of the "Media Contacts 15" option closed.
Cannot transfer the load to Main 2 due to:
– transfer conditions not satisfied;
– UPS operating on an independent frequency;
– UPS operating with current limitation;
– internal fault;
– auxiliary control inhibits switching to Mains 2.
