Installing the PROFIBUS Adapter
General
This chapter describes how to install and wire your adapter.
When properly installed, POINT I/O is grounded through the DIN rail
to chassis ground. Use zinc plated, yellow chromated steel DIN rail to
assure proper grounding.
Other DIN rail material (such as aluminum, plastic, etc.) can corrode
or oxidize and are poor conductors that may result in improper or
intermittent platform grounding.
If you choose not to use zinc plated, yellow chromated steel DIN rail
for your POINT I/O, periodically clean the DIN rail to prevent or
lessen the effects of oxidation and corrosion.
