The active loops must be isolated or bypassed prior to mechanical disconnection.\u003c\/p\u003e\n\u003cp\u003eQ: What is the mechanical life expectancy and connection capability of the field screw terminals on this block?\u003c\/p\u003e\n\u003cp\u003eA: The solid screw terminal blocks are designed for standard industrial gauge wire applications up to 2.5 mm squared, providing gas-tight physical pressure connections capable of resisting long-term high-vibration field degradation.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShield Grounding Termination:\u003c\/strong\u003e Terminate all individual 4-20 mA twisted-pair cable shields directly to the designated instrument ground bus bar inside the marshalling cabinet.
