connection)
Note
: “J3” or “J7” must only be shunted if the unit is the last unit on the RS485 bus.
J5
Primary terminal block to connect to FDCIE or next unit
J6
Secondary terminal block, is used for redundant connection of communication and
power supply, when this is supported by the FDCIE (new 5012 in G3).
Note
: In the 4556 for FT128 and 5010 in FT1020G3, the redundant connection is not available.
The redundant path can be used only in the new 5012 main board for G3 (when released).
