Mount the Module
Mount the module on a 35 x 7.5 mm (1.38 x 0.30 in.) DIN rail, Allen-Bradley part number 199-DR1, 46277, EN 50022.
ATTENTION: This product is grounded through the DIN rail to chassis ground. Use zinc-plated yellow-chromate steel DIN rail to assure proper grounding. The use of other DIN-rail materials (for example, aluminum or plastic) that can corrode or oxidize, or are poor conductors, can result in improper or intermittent grounding.
Secure DIN rail to mounting surface approximately every
200 mm (7.87 in.) and use end-anchors appropriately.
TIP When using the 1786-RPFM module, we recommend horizontal mounting if cabinet temperatures are expected to approach
60 °C (140 °F). If your expected temperatures are much lower than 60 °C (140 °F), vertical mounting is acceptable. If using vertical mounting, we recommend that the 1786-RPA repeater adapter module be mounted at the top.

IMPORTANT Make certain that you secure the adapter and repeater modules with DIN-rail anchors. If you do not, loss of communication or module damage may result.
Consult with your local distributor for attenuation specifications before you purchase your fiber media components.

You can attach a maximum of four modules to the repeater adapter, or, the number of modules whose total power consumption does not exceed
1.6 A @ 5V DC, whichever occurs first.
IMPORTANT If you exceed the module or power limit, you may damage the repeater adapter and modules.
Select Fiber Cable
The type of fiber cable you choose depends on the network environment. The quality of fiber cable determines the distance you can achieve. The maximum length of a fiber cable section for the module depends on the quality of fiber, number of splices, and the number of connectors. The total attenuation for a cable must be less than 13.3 dB. Typically, cable attenuation for a wavelength of
1300 nm is less than 1.5 dB/km.
Refer to the specification table on page 13 and also to the ControlNet Fiber
Media Planning and Installation Guide, publication CNET-IN001 , for more details.
Also, consult with your local distributor for attenuation specifications before you purchase your fiber media components.
IMPORTANT Avoid splicing your cable. Connectors can cause considerable attenuation and limit the maximum length of your system. Make certain to check the attenuation of different cable sections after you install the cable.
Terminate Your Cable
You must terminate a medium distance cable in the field. To terminate, we recommend that you cover unused ports with a suitable protector cap to prevent dust and other contaminants from damaging the fiber transceiver ports.
For unused ports, we recommend that you place a simplex jumper between the transmit port and receive port of an unused channel.

ControlNet Modular Repeater Medium-distance Fiber Module 11
Connect the Fiber Module
If you are wiring only one channel, you can use either channel 1 or channel 2.
Do these steps to connect to channel 1, receive (RX).
1.
Align the knob of the cable connector with the groove of the module connector.
2.
Insert the connector into channel 1 RX.
3.
Twist the receive connector until the bayonet lug locks into place.
4.
Repeat these procedures to connect to channel 1, transmit (TX).
IMPORTANT Make certain the fiber cable you connect to channel 1 ( receive) on one module is set to channel 1 (transmit) on the other module.
You can use channel 1 or channel 2 on either module.
ATTENTION: Under certain conditions, viewing the optical port may expose the eye to hazard. When viewed under some conditions, the optical port may expose the eye beyond the maximum permissible exposure recommendations.
