After installing all your expansion racks and connecting them with the 468-3 interface cables, locate the \u003cb\u003elast IM 461-3 module\u003c\/b\u003e in the physical chain (farthest from the central rack). Insert the \u003cb\u003e6ES7461-3AA00-7AA0\u003c\/b\u003e termination plug firmly into its dedicated socket on that module. This completes the bus circuit. Do not install it on any module other than the last IM 461-3.\u003c\/p\u003e\n\u003ch3\u003ePackage Contents \u0026amp; Warranty\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eWhat's Included:\u003c\/b\u003e 1 x Siemens Termination Plug (6ES7461-3AA00-7AA0).\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eOur Guarantee:\u003c\/b\u003e This accessory is covered by a full \u003cb\u003e12-month warranty\u003c\/b\u003e.\u003c\/p\u003e\n\u003ch3\u003eFast Global Shipping\u003c\/h3\u003e\n\u003cp\u003eWe ensure prompt delivery worldwide via \u003cb\u003eFedEx, UPS, and DHL\u003c\/b\u003e.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions (FAQ)\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eDo I need this for every IM 461-3 module?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eNo. You need only \u003cb\u003eone termination plug\u003c\/b\u003e, and it must be installed \u003cb\u003eonly on the last IM 461-3 module\u003c\/b\u003e in the communication chain. Installing it on an intermediate module will break the bus.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWhat happens if I don't use the termination plug?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eWithout proper termination, electrical signals can reflect back on the bus cable, causing communication errors, sporadic I\/O faults, or complete failure of the expansion racks. It is a critical component for reliable operation.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eIs this plug the same for IM 461-0 or IM 461-1?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eNo. Different IM receiver models require different termination plugs. For example, the IM 461-0 uses termination plug \u003cb\u003e6ES7461-0AA0-7AA1\u003c\/b\u003e. Always use the termination plug specified for your exact receiver module type.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCan I use a homemade wire bridge instead?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eIt is \u003cb\u003estrongly discouraged\u003c\/b\u003e. The Siemens termination plug is an engineered component with specific electrical characteristics. Using an incorrect termination can lead to unreliable system performance and is not supported.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWhere does it physically plug in?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eOn the front of the IM 461-3 module, there is a specific socket or slot, often labeled or located near the address switches. The termination plug inserts directly into this socket.\u003c\/p\u003e\n\u003cp\u003e© 2025 Ubest Automation Limited.
