6.1.1 Power Limitations
Maximum output currents VisuNet FLX system installation
Refer to the VisuNet FLX Panel Mount manual and BPC3200-* manual to get detailed informa-
tion on the maximum output current of these installations.
Caution!
Damage to the electronics!
The electronics can be damaged if plug-in connections are connected or disconnected while
power is still being applied.
Make sure that no power is being applied while connecting and disconnecting cables!
Warning!
Interfaces must have a strain relief in Ex-operation.
This can be achieved with the ATEN Locks (#548400)
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.
