Power Limitations

Caution!
Our units are power-limited for compliance with Ex requirements and protection against over-
heating. For this purpose, the maximum operating conditions (maximum operating temperature
at maximum load) are considered.
It is absolutely necessary to consider maximum allowed output currents when installing the Vis-
uNet FLX in Zone 2/22 environment.

Note
For Non-Ex applications, these parameters serve as guide values and allow an increase of the
VisuNet FLX system service life.
Refer to the VisuNet FLX Panel Mount manual and BPC3200-* manual to get detailed informa-
tion on the maximum output current of these installations.
