Help Text
Cannot write to flash - hardware may be defective.
Unable to read EEPROM. Device is defective.
An attempt was made to update the software with
an update file that is not suitable for the DC PS.
Error during software update - try to update the
software again.
An attempt was made to update the software with
an invalid update file. The update file is probably too
old.
An entry in the software update cannot contain more
than 32 bytes of reference data.
Device failure
Buffer mode is not possible - check settings, ca-
bling, fuse, and battery voltages
Device temperature is very high! Ensure adequate
cooling or disconnect unnecessary loads.
Device temperature is very low! Ensure a higher
ambient temperature.
High-resistance connection to battery - check the
battery power cables.
Connection to battery interrupted - check connection
and fuse.
Data from the battery cannot be read correctly.
Battery is defective or not supported by SIEMENS.
Output current of DC UPS is too high. Output is
switched off for 20 s The output is switched on
again after 20 s.
Input voltage at DC UPS was OK again before the
buffer time expired. Connected devices are reset by
switching off the DC UPS outputs for the configured
time.
Battery "State of Health" tests (SoH) are performed.
The output of the DC UPS is connected to the bat-
tery in order to determine the actual battery capaci-
ty.
Input voltage exceeds 30 V. DC UPS is not opera-
tional.
More than 6 batteries are connected. Connect a
maximum of 6 batteries to the Energy Storage Link.
software.
Output and battery charging is switched off to pre-
vent damage to the device.
Battery "State of Health" tests (SoH) are performed.
Input voltage of DC UPS is too low. DC UPS is not
ready for buffering.
Device is in the buffer mode.
