ATTENTION
Mounting 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.
UNSUPPORTED CONNECTION
Do not connect a MicroLogix 1100 controller to another
MicroLogix family controller such as MicroLogix 1000,
MicroLogix 1200, or MicroLogix 1500 using a 1761-CBL-AM00
(8-pin mini-DIN to 8-pin mini-DIN) cable or equivalent.
This type of connection will cause damage to the RS-232/485
communication port (Channel 0) of the MicroLogix 1100
and/or the controller itself. Communication pins used for
RS-485 communications are alternately used for 24V power on
the other MicroLogix controllers.
