It is good practice to use isolated measurement cables. However, since the voltage
range of the Isolated Basic card falls below the low voltage limit for accessible parts,
non-protected or non-shrouded connectors can also be used with this card.

The isolation of the Isolated Basic card (GN815 and GN816) is in line with the limit for
safe voltage and currents as mentioned above.
