ATTENTION: When breaking connections at Terminal J2 on any
Node Adapter Board in a daisy chained system, communications
will be interrupted to Nodes that are down line in the chain.
Depending upon the application, a loss of control to devices
connected to these nodes could cause hazardous system operation.
To guard against personal injury, the system must be shut down, or
local control maintained of critical devices connected to the daisy
chain when making or breaking connections at J2 on any Node
Adapter Board.
