Step 2.

If the power supply you are using is 24 VDC, replace the

factoryĆinstalled .25A fuse with the .75A fuse that came in

the shipping box with the module. Use a screwdriver to

release the fuse holder located on the Analog Rail

module faceplate. Pull the fuse holder out of the module.
Take the .25A fuse out of the fuse holder and replace it

with the .75A fuse. ReĆinsert the fuse holder into the

module. Turn the screwdriver clockwise while pressing

down on the fuse holder. The fuse holder must be flush

against the faceplate.

Step 3.

Mount the Analog Rail on the panel and attach it securely

to the wall with #10 (M5) studs or bolts.

Step 4.

Make certain that no voltage is present on the wires that

will be used to provide 120 VAC or 24 VDC power to the

Analog Rail module. Use either a 120 VAC or 24 VDC

power supply, but not both.

Step 5.

Using 14 AWG wire, connect input power to the screw

terminals on the Input Power" plug connector on the

faceplate as shown below. Strip off approximately 5/16"

of insulation from the wires.

Step 6.

Use the stud marked GND" (ground) on the bottom right

flange of the module to connect a ground wire.

Step 7.

Turn off all power to any external hardware that will

provide input signals to the module or be powered by the

module.

Step 8.

Attach a retainer clip to the connector at each end of the

I/O Rail cable (M/N 45C5). Note that faceplate connectors

have slots that correspond to the part of the retainer clip

that protrudes away from the cable connector. The

retainer clip is used to assure a tight connection between

the cable and faceplate connectors.

Step 9.

Using 14Ć22AWG wire, connect external hardware to the

Analog Inputs" plug connector on the faceplate as

shown below. Strip off approximately 5/16" insulation

from the wires.
