Subject to change without notice
The ground loop is isolated by using the electro-optical signal isolator between the
islands. Within the islands, 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
sensor and of peripheral devices may be a sufficient solution.
Even in the event of large differences in the ground potential, ground loops are
effectively prevented. As a result, equalizing currents can no longer flow via the cable
shields and metal housing.
Important!
The voltage supply of the TiM361S safety-related laser scanner and of the
connected peripheral devices must also guarantee the required insulation level. Under
certain circumstances, a tangible potential can develop between the insulated metal
housings and the local ground potential.
