For more information on wiring, see Allen-Bradley
Programmable Controller Grounding and Wiring Guidelines,
publication 1770-4.1.
Refer to publication 1746-IN016, for chassis installation and
grounding requirements.
Set the input jumper before applying power. Hazardous
voltage is present on exposed pins when power is
applied; contact with the pin may cause injury to
personnel.
If you connect or disconnect the wiring to the terminal
blocks or if you insert or remove the power supply while
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.
