Disconnect-Style and Fuse-Style Interposing I/O Bases, Terminal Wiring
Each terminal accommodates:
One solid (0.2 to 4.0mm
2
cross section) or stranded (0.2 to 2.5mm
2
cross
section), AWG #12 to AWG #24.
When inserting two wires in the same position, the wires must be the same size
and type (solid or stranded):
Rigid or flexible wires: 0.2 to 1.5mm2 cross section.
Stranded wires with ferrules, no plastic sleeve: 0.25 to 0.75mm
2
cross
section
Stranded wires with twin ferrule, with plastic sleeve:
Upper level (A/B terminals): 0.5 to 1.5mm
2
cross section
Lower level (W/X/Y/Z terminals): 0.5 mm
2
cross section
Recommended torque for the terminal screws is 0.5 to 0.6 Nm.
Disconnect-Style and Fuse-Style Interposing I/O Terminals,
Wiring for Modules with One Group per Row
This wiring format generally applies when the associated VersaMax module
provides for connection of I/O in 16-point groups. An example of such a module
is the VersaMax 24 V DC 16pt Output Module, IC200MDL740:

When connecting an Interposing Disconnect or Fuse base in this format, follow
these guidelines:
Connect the field devices to A1-A16 (or B1-B16 where appropriate)
Connect the return wires of field devices to the corresponding common
connections – A1 to W1, A2 to W2, A9 to X1, A10 to X2, and such.
Connect jumpers between the A17, W, and X terminals (or B17, Y, and Z)
Connect the power supply between A17 and A18 (or B17 and B18)
