Install POINT I/O Modules

Position the mounting base (wiring base assembly) vertically above the
installed units (adapter, power supply, or existing module).

Slide the mounting base down, allowing the interlocking side pieces to
engage the adjacent module, power supply, or adapter.

Press firmly to seat the mounting base on the DIN rail.
