in accordance with IEC 60079-14.
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.
