Maintain consistent cable shielding and termination practices for analog loops. Connect shields according to the system grounding design and avoid creating unintended ground loops.\u003c\/p\u003e\n\u003cp\u003eCheck each field-channel fuse and wiring termination before commissioning. Confirm that the connected field device type and loop configuration correspond to the intended channel arrangement.
