Hi,
We recently ordered a Hameg EMC-PCS3 EMC precompliance set to allow us to perform conducted emissions tests at our R&D office. This set includes the HM6050-2 Line Impedance Stabilization Network, which according to the manual, looks to be simple enough to setup. Our supplier was unable to provide this LISN with the set, instead sending us a Rhode and Schwarz ENV216 2-line V network which we were told was basically a higher-end LISN. Upon comparing the manuals for both devices, it does seem the V network is a bit more involved with the initial setup than the LISN - in particular, for protective grounding, in addition to the ground pin on the mains input plug, it asks for a 'further' grounding conductor with 'adequate' diameter to be connected to the grounding bolt of the V network. The LISN by comparison, appears to just use the grounding connection provided on the mains input plug.
I understand this requirement is for protection, but I am left not quite understanding what would be suitable for the V network's 'further' grounding connector. Would a connection to a second power socket's ground connector be adequate, or is something more needed, such as a direct connection to a grounding stake outside our office? It would be much appreciated if someone could offer some insights into the connection required for this additional ground. The manual refers to IEC 60364-5-54, which I unfortunately do not have access to at this stage.
Kind Regards,
