Page 6: About The Fiber Module
ControlNet Modular Repeater Medium Distance Fiber Module About the Fiber Module Use this module when a medium-distance (distances of 3000m/ 9843ft) fiber link is required between two ControlNet products. This fiber link provides ground isolation between nodes and is less susceptible to noisy environments than traditional copper media.
Page 7: Mount The Fiber Module
ControlNet Modular Repeater Medium Distance Fiber Module Mount the Fiber Module To mount the module on the DIN rail: 1. Position the module on a 35 x 7.5mm DIN rail (Allen- Bradley part number 199- DR1; 46277- 3; EN 50022) at a 30 angle.
Page 8 ControlNet Modular Repeater Medium Distance Fiber Module 3. Press the module down onto the DIN rail until flush. The locking tab should snap into position and lock the module to the DIN rail. 4. If the module does not snap into position, use a screwdriver or similar device to move the locking tab down while pressing the module flush onto the DIN rail.
