Wire the I/O Removable Terminal Blocks
To begin wiring your embedded I/O removable terminal blocks, loosen the screws
at the top and bottom of the removable terminal block and remove the removable
terminal block from the packaged controller.
Reference the wiring diagrams specific to each type of embedded I/O as shown in
the following pages.
WARNING
When you connect or disconnect the Removable Terminal Block (RTB) with field side
power applied, an electrical arc can occur. This could cause an explosion in hazardous
location installations.
If you connect or disconnect wiring while the field-side power is on, an electrical arc
can occur. This could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
ATTENTION
Mis-wiring the removable terminal blocks to an AC power source causes damage
to the packaged controller.
Be careful when stripping wires. Wire fragments that fall into an removable
terminal block could cause damage at power up. Once wiring is complete, ensure
the removable terminal blocks are free of all metal fragments.
When wiring I/O removable terminal blocks, tighten terminal screws with care.
Excessive tightening can strip a screw.
