Malfunctions

The Protect B. PRO outputs detailed fault indications which you
or the service personnel can use to quickly and precisely localise
and interpret malfunctions which occur. Below you will find
suggested processes/solutions for remedying the problem you
are experiencing.
If you are not able to solve the problem in this manner, end the
entire process, switch off the UPS and disconnect the UPS from
the mains. In this case, please contact our hotline (see Page 5).
Have the serial number of the device and the date of purchase
handy when doing so. You will be provided with technical
support, and a decision on how to proceed further is made based
on the description of your problem.
