4. Product Introduction & Supply Chain Strategy
The Eaton MTL 8602-FT-ST field terminal block serves as the interface between field cabling and sensitive I/O electronics in the MTL 8000 distributed I/O family. By housing the field wiring screw terminals on a passive base, it allows active I/O modules to be hot-swapped without disturbing field wiring looms.
Stocking an uninstalled MTL 8602-FT-ST in reserve as New Surplus is an essential maintenance practice for continuous process facilities. Physical damage to terminal screws or mounting latches during routine maintenance can jeopardize signal integrity and disrupt loops. Having factory-sealed terminal assemblies on site ensures immediate replacement without requiring rewiring of neighboring channels or system retrofits.

5. Installation & Configuration Guide
Hazardous Area & Electrical Safety Warning
Ensure field power is isolated and the area is confirmed non-hazardous before making or breaking field connections on the terminal assembly in Class I, Div 2 / Zone 2 environments.
1.Power Isolation & Area Verification:Prerequisite.
Isolate field instrument power supply feeds and verify that the local atmosphere is safe before opening enclosure access covers.
2.Terminal Base Installation:Carrier Mounting.
Snap the 8602-FT-ST field terminal assembly firmly onto the designated slot on the MTL 8000 carrier rail until the mechanical locking latches engage.
3.Termination Landing:Field Wiring.
Strip instrument wire leads appropriately and land wires onto designated screw terminals according to the loop drawing. Tighten screws to recommended torque settings.
4.I/O Module Alignment:Module Insertion.
Set the mechanical keying position on the field terminal base to match the assigned I/O module type, then seat the active I/O module onto the assembly.
6. Firmware/Software Versions & Upgrade Notes
- Passive Assembly: The 8602-FT-ST is a passive mechanical/electrical termination base requiring no software or firmware configuration.
- Mechanical Keying: Features configurable mechanical keying pegs to prevent incorrect I/O module insertion into the field terminal slot.
- Terminal Variant: The “-ST” suffix indicates standard screw terminals (alternative “-CC” variants utilize spring-clamp connections).
7. Frequently Asked Questions (FAQ)
Q: Is this Eaton MTL 8602-FT-ST unit genuinely new?
A: Yes, this item is a Brand New Surplus unit. It has never been installed in a cabinet or connected to active process loops, and is preserved in protective packaging.
Q: What does the “ST” stand for in 8602-FT-ST?
A: “ST” stands for Standard Screw Terminals, specifying threaded terminal connection points for field wiring.
Q: Can I replace an active I/O module without removing the field wiring on this terminal?
A: Yes. The MTL 8000 modular design allows active I/O modules to be unplugged directly from the 8602-FT-ST base while field wires remain landed on the terminal block.
Q: What warranty accompanies this unit?
A: Every MTL 8602-FT-ST unit comes with a full 1-year replacement warranty and quality inspection prior to dispatch.
