9 Troubleshooting

9.1 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.
