Turning off the FX80
You must NEVER turn off the FX80 by means of the on/off switch on the Processor
Unit. You must always close the FX80 program by selecting
Exit
on the top bar.
Context
When you do not use the FX80, turn off the display and the Processor Unit. It is
important that you disconnect the high voltage power to the Communication Hub. To
disconnect the high voltage power, switch off the Bridge Control Unit.
Caution
Do not connect or disconnect any cables while the system is turned on. Do not leave
power on to ports that aren’t connected to anything (even if there are dummy plugs
installed).

mounted switch to power on (and off) the unit.

provided by the operating system to turn it off manually.
