Step 12. Turn off power to the Reliance device that will be

connected to the Analog Rail module.

Step 13. Set the Mode" switch on the faceplate of the Analog Rail

moduleto thedesired position.

Step 14. Connect the I/O Rail cable between the Analog Rail

connection labeled Input" and an I/O port on the

Reliancedevicethat will communicatewith themodule.

Turn on power to the Reliance device that will

communicatewith theAnalog Rail module. Recall that the

Modeswitch is read each timetheReliancedevice

connected to the module is powered up.

Step 15

The Analog Rail installation is now ready for testing.

Inspect all work to assure that the installation has been

performed properly.

Step 16. Turn on power to the Input Power" wiring. Turn on power

to the external hardware. Recall that external hardware

being powered by the output of the Analog Rail module

must be in series with an external power supply. See

figure3.2. SeeAppendix A for thepower supply

specifications.
