Grounding the Housing to the Pedestal

When installing the VisuNet GXP system, always ensure that all components are properly
grounded, including housing and mounting parts (e.g., pedestal and wall bracket) with a cable
diameter of at least 4 mm
When the AG-XX00 housing option is selected, the VisuNet GXP is shipped with the following
PE connections:
• PE wire from the DPU PE stud to the AG-XX00 housing PE stud
• PE wire from the PSU PE stud to the AG-XX00 housing PE stud
If you replace the DPU or PSU, reestablish the PE connection in the same configuration.
Tighten the PE hardware to 7.5 Nm.

explosive atmosphere.
