Installing the C20
Overview
But first...
This chapter tells you how to install the C20. You may wish to skip this
section and go first to Chapter 3, Introduction to programming, which
provides important information on how to determine the configuration of
your controlling system.
The following are some important points that should always be observed
to ensure correct installation and operation of the C20.
Static electricity
in low-humidity conditions, static electricity may cause problems with the
C20's components. Therefore, before touching the C20, be sure to first
touch a grounded metallic object to discharge any static electricity
buildup.
Memory chips

program memory, according to your application.
