Maintenance and service

Defective modules
Warning
The devices contain no user serviceable or configurable
parts!
Therefore:
•
Do not open the devices. Maintenance works inside the
devices are not necessary.
In case of an evident hardware defect please send the
defective device with a detailed description of the fault to
your service point.
Modules sent to our service points that are not defective
cause much work and high costs. Please check yourself
carefully beforehand whether the failure is caused rather
by an erroneous configuration, operation or connection
Thank you!
