4.17 Uninterrupted Power Supply (UPS)

It is strongly recommended to operate the WERA from an UPS unit. At least the WERA

User Interface PC should be connected to such a unit to guarantee a controlled and safe

ramping down of the PC in case of a power failure. The hard- and software of the ups

needs to be configured to safely shut down the PC in case of a longer power loss.

So a data link and software between the PC and ups is required.

In case of a very insecure power line, it might be better to operate the WERA system from

a UPS that continuously is generating the AC. Please contact factory to get more

information about these options.

4.18 Lightning Protection (-Plate) for WERA 8- channels

All WERA installations needs to be equipped with professional lightning protection units. If

the WERA electronics not housed in the original WERA container it is very important to

feed-in all cables via lightning protection filters. These filters are provided by Helzel, 8

surge protectors mounted on one plate. This plate needs to be connected to “Earth”

potential by means of a suited cable (a 10 mm

cable is enclosed). Please carefully check

these connections and if there are any doubts, please contact Helzel factory or a local

service company for help.

For the WERA 12-channel systems with AIP, the lightning protection is integrated in the

RIN filters.

Some models have a separate lightning protection plate, depending on the system

configuration.
