Field Installation Guidelines
Install the VI701 securely into the designated FCU slot or I/O nest.
Connect Ethernet cabling according to system design (copper or fiber).
Verify redundancy paths during commissioning.
Maintain shield grounding at a single point to prevent ground loops.
Separate control network cabling from high‑voltage wiring to minimize interference.
