Install the Module 9
You can install the assembly, or just the mounting base.
Follow this procedure to install the mounting base/wiring base assembly on
the DIN rail.
1. Position the mounting base (wiring base) assembly vertically above the
installed units (adapter, power supply, or existing module).
2. Slide the mounting base down so that the interlocking side pieces
engage the adjacent module or adapter.

ATTENTION
POINT I/O is grounded through the DIN rail to chassis ground.
Use zinc-plated, yellow-chromated steel DIN rail to assure
proper grounding. The use of DIN rail materials (such as
aluminum and plastic) that can corrode, oxidize, or are poor
conductors can result in improper or intermittent grounding.
Secure DIN rail to mounting surface approximately every
200 mm (7.8 in.).
ATTENTION
Do not discard the end cap shipped with an adapter or
communication interface. Use this end cap to cover the exposed
interconnections on the last mounting base on the DIN rail.
Failure to do so could result in equipment damage or injury from
electric shock.
