Wiring Your Controller 3-7
This product is intended to be mounted to a well grounded mounting
surface such as a metal panel. Refer to the Industrial Automation
Wiring and Grounding Guidelines, publication 1770-4.1, for
additional information. Additional grounding connections from the
mounting tabs or DIN rail, if used, are not required unless the
mounting surface cannot be grounded. You must also provide an
acceptable grounding path for each device in your application.
TIP
It is recommended to use all four mounting positions
for panel mounting installation.
TIP
This symbol denotes a protective earth ground
terminal which provides a low impedance path
between electrical circuits and earth for safety
purposes and provides noise immunity
improvement. This connection must be made for
safety purposes
ATTENTION
!
Remove the protective debris strips before applying
power to the controller. Failure to remove the strips
may cause the controller to overheat.
