Mount the System
Maintain spacing from enclosure walls, wireways, and adjacent equipment.
Allow 50 mm (2 in.) of space on all sides, as shown. This provides ventilation
and electrical isolation. Dimensions are in mm (in.) in the figure.

ATTENTION
When attaching the controller, power supply, and I/O modules, make sure the
bus connectors are securely locked together to be sure of proper electrical
connection.
IMPORTANT
When mounting the CompactLogix system, either use screws to panel
mount system or use DIN rail. Do not use both. Use of both mounting
methods may cause hardware damage and cause the system to fail.
ATTENTION
During panel or DIN rail mounting of all devices, be sure that all debris (such
as metal chips or wire strands) is kept from falling into the controller. Debris
that falls into the controller could cause damage while the controller is
energized.
