"Hazardous areas require the use of specifically designed
products. This product is designed for Class I, Division 2
hazardous environments, and nonhazardous environments
only. Allen-Bradley provides similar products which are
intrinsically safe and are suitable for more hazardous
environments. Use the appropriate products that are designed
for the specific hazardous environments that your installation
requires.
In intrinsically safe applications, consult with your local safety
coordinator, and publication CNET-IN003A-US-P, the
ControlNet EX Media Planning and Installation Manual because
you need specific products on both ends of the fiber link."

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.
The module provides:
•two fiber channels
•activity LED indicators for each fiber channel
Figure 1 Components of the Module
IMPORTANT The distance that can be supported is dependent on the quality
of the fiber, number of splices, and connectors. The total loss of
the fiber link must be less than 13.3 dB.

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 30oangle.
2. Hook the lip on the rear of the module onto the top of the DIN rail, and
rotate the module onto the rail.

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. Release the locking tab to lock the module in place. If
necessary, push up on the locking tab to lock.

Publication 1786-IN011B-EN-P - October 2000
5. Remove the protective backplane cap as shown in “Remove the Protective
Caps” on page 10.
6. Once attached to the DIN rail, slide modules to the left to mate with the
repeater adapter or another repeater module.
7. Connect the fiber cable as shown in “Connect the Fiber Cable” on page 13.
ATTENTION
!
Be certain that the adapter and repeater modules are secured
together with DIN rail anchors. Failure to do so may result in
the loss of communications and/ or cause damage to the
modules. The total number of modules that can be attached to
the repeater adapter can not exceed four or the total power
consumption of the modules can not exceed 1.6A @ 5VDC,
whichever comes first.
IMPORTANT
If you exceed the module or power limit, you may cause
damage to the repeater adapter and modules.
IMPORTANT
If this is the right–most module, a DIN rail latch must be used
on the right side of the fiber module.

Remove the Protective Caps
1. Remove the protective caps from the fiber ports that you are going to use.
2. Save the caps for future use.
Figure 2 Protective Caps
If you plan: Then:
not to use channel(s) keep the protective caps on the channels to protect
the unit from dust.
to place the module in storage keep the protective caps on the channels to protect
the unit from dust.
to connect another module to the right
backplane connector
remove the protective backplane cap and save cap
or future use.
not to connect to the right backplane connector leave the backplane cap on.
