Mount the Controller
General Considerations
Most applications require installation in an industrial enclosure to reduce the effects of
electrical interference and environmental exposure. Locate your controller as far as possible
from power lines, load lines, and other sources of electrical noise such as hard-contact
switches, relays, and ac motor drives. For more information on proper grounding guidelines,
see the Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1
.
ATTENTION
Mount the controller horizontally only. Vertical mounting is not supported due to
thermal considerations.
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.
WARNING
Do not place the MicroLogix 1400 Programmable Controller in direct sunlight.
Prolonged exposure to direct sunlight could degrade the LCD display.
WARNING
The local programming terminal port is intended for temporary use only and
must not be connected or disconnected unless the area is assured to be
nonhazardous.
