Protect 5.31/xxx-480-220-120 10 kVA - 120 kVA
The comprehensive diagnostic functions implemented in the UPS not
only increase its operational reliability considerably, but also reduce
the time required for maintenance work and troubleshooting to a
minimum.
The UPS is equipped with the following diagnostic functions, some of
which are optional:
Self-diagnosis:
This is activated when the system is switched on. Internal auxiliary
programs monitor and signal faults, including those from the bus
system, the control PCBs or the sensors.
Data logger:
Specified measuring data and parameters from the REC, INV and
SBS are stored in the event of a fault. This data is read out and
evaluated as required.
CAUTION:
Some repair work, e.g. replacing a fan fuse, can also be
performed when the system is in operation and live.
Always observe the safety regulations!
ATTENTION:
Do not switch the battery under load!
