Module Mounting Locations View #1
Notes:
For many adder modules to enable communication from the main module to all of the
adder modules, it is necessary to add a continuity jumper on the last adder module in a
chain (see the appropriate module settings section to verify the location of the continuity
jumper on a particular circuit adder module). Only the last circuit adder module should
have a jumper plug on its continuity jumper; all others must be left without a jumper plug.
1. Front plate is not shown.
2. Position reserved for PR-300 or UDACT-300A.
