Connecting a GroundCable
To ensure personal and equipment safety (lightning protection and
resistance against interference), ground the device properly.
The ground cable must not exceed 30m and provides a grounding
resistance of less than 5 Ω. For specific requirements, refer to the
standards for the IEC61024 series.
As shown in the following figure (NVR308-32L/16L/09L-IN, for example),
connect one end of the ground cable to the ground terminal of the
device and the other end to a reliable grounding point.
