2-12 Installing Your Controller
Mounting the Controller
ATTENTION
!
Do not remove protective debris strips until after the base and all
other equipment in the panel near the base is mounted and
wiring is complete. The debris strips are there to prevent drill
fragments, wire strands and other dirt from getting into the
controller. Once wiring is complete, remove protective debris
strips and install processor unit. Failure to remove strips before
operating can cause overheating.
ATTENTION
!
Be careful of metal chips when drilling mounting holes for your
controller or other equipment within the enclosure or panel.
Drilled fragments that fall into the controller could cause
damage. Do not drill holes above a mounted controller if the
protective debris strips have been removed.
ATTENTION
!
Electrostatic discharge can damage semiconductor devices inside
the base unit. Do not touch the connector pins or other sensitive
areas.
NOTE
If additional I/O modules are required for the application,
remove the ESD barrier to install expansion I/O modules. A
maximum of 8 I/O modules may be connected to the base. The
I/O module’s current requirements and power consumption may
further limit the number of modules connected to the base. See
System Loading and Heat Dissipation on page F-1. An end cap
terminator (catalog number 1769-ECR or 1769-ECL) is required
at the end of the group of I/O modules attached to the base.
