You are now ready to begin adding Click modules to your cabinet. This chapter will discuss
an important element of installation: wiring communication through the screw terminals.
Because all Click 500 applications are based on the same physical device, they all have the
same communication ports. However, some applications do not use all of these; this will be
discussed in each application’s chapter in Part II of this guide.
Working with Screw Terminal Blocks
The Click 500 series devices feature screw terminal blocks for wiring connections. These
screw terminal blocks simplify wiring because they can be removed from the Click device,
then wired and reinserted.
To remove a screw terminal block, insert a small, thin item, such as a small screwdriver, into
the gap between the screw terminal block and the Click device (just above the screw heads)
and gently pry the two apart.
After wiring, simply reinsert the screw terminal block and push until it snaps into place. The
screw terminal blocks are red-keyed, meaning they will only plug into their specific jacks.
