Installation

The following diagram illustrates installation of a Hot Standby System.

Setting	The designation slide switch on one Hot Standby module is set to A and the other is
Designation	set to B.
Slide Switches

		CAUTION

		HAZARD
		Before installing any controller in your Hot Standby system, be sure its
		battery has been disconnected for at least five minutes.
		Failure to follow this precaution can result in injury or equipment
		damage.


	Note: Be sure your system meets the power and grounding guidelines outlined in
	Appendix D of the Quantum Automation Series Hardware Reference Guide, 840
	USE 100 00.

Connect Network The following diagram shows how to connect the network.

Step

Action

1Install a splitter and a self-terminating F adapter between the primary RIO head processor and the RIO network.

2Connect the coaxial cable link.

3Connect the cable between the splitter, another self-terminating F adapter and the standby RIO head processor
