SICK PLOC2D 4.1 - Connectors and Pin Assignment

The use of electro-optical signal isolators between the islands isolates the ground loop.
Within the islands, a stable equipotential bonding prevents equalizing currents on the
cable shields.
Measures for small system installations
For smaller installations with only slight potential differences, insulated mounting of the
SICK device and of peripheral devices may be a sufficient solution.
Even in the event of large differences in the ground potential, ground loops are effec‐
tively prevented. As a result, equalizing currents can no longer flow via the cable shields
and metal housing.
NOTICE
The power supply for the SICK device and the connected peripheral devices must also
guarantee the required level of insulation.
Under certain circumstances, a tangible potential can develop between the insulated
metal housings and the local ground potential.
