Recommended max. cable length 5m (16,4ft).
Pay attention to the values listed in corresponding standards.
This variant is developed with internal energy buffer to provide the necessary
power for the scanner electronic (duty cycle typ. 5%). A pre- charging of typ.
16h for this internal buffer necessary before first operation.
