6. Attach the DIN rail locks to the left side of the repeater adapter module
and the right side of the attached modules to lock the repeater adapter
module and modules in place.
WARNING: Removal and insertion under power (RIUP) is not
supported. This module must be powered down while connecting
and disconnecting it from any interconnected modules.
If you insert or remove the module while backplane power is on, an
electrical arc can occur. This could cause an explosion in hazardous
location installations.
Be sure that power is removed or the area is nonhazardous
before proceeding.
IMPORTANT Make certain that the repeater adapter and modules are secured
together with DIN rail locks on either side. Failure to do so may
result in the loss of communication and/or cause damage
to the modules.
IMPORTANT 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 8 W or
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. The maximum current draw at
5V DC is 400 mA for the 1786-RPFM module, 300 mA for the
1786-RPFS module, and 499 mA for the 1786-RPCD module.
If you exceed the module or power limit, you may cause damage
to the modules and repeater adapter.
