Mount the Fiber Modules
This section explains how to mount the module.
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 communication and/or cause damage to the
modules.
The total number of modules that can be attached to the 1786-RPA/B
repeater adapter cannot exceed four or the total power consumption
of the modules cannot exceed 1.6 A @ 5V DC, whichever comes first.
The 1786-RPFRL/B and 1786-RPFRXL/B modules require 570 mA each,
therefore you can attach only two of these modules to a
1786-RPA/B repeater module.
If you exceed the module or power limit, you may cause damage to the
modules and repeater adapter.
TIP Horizontal mounting is preferred. Vertical mounting is allowed.
We recommend that the 1786-RPA/B module be mounted at the
top if vertical mounting is chosen.
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, oxidize, or are poor
conductors, can result in improper or intermittent grounding.
Secure DIN rail to mounting surface approximately every 200 mm
(7.8 in.) and use end-anchors appropriately.
