Overview
MicroLogix 1100 controllers are suitable for use in an industrial environment when installed
in accordance with these instructions. Specifically, this equipment is intended for use in clean,
dry environments (Pollution degree 2
(1)
) and with circuits not exceeding Over Voltage
Category II
(2)
(IEC 60664-1).
(3)
Install your controller using these installation instructions.
(1)
Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that occasionally a
temporary conductivity caused by condensation shall be expected.
(2)
Over Voltage Category II is the load level section of the electrical distribution system. At this level transient voltages are
controlled and do not exceed the impulse voltage capability of the product’s insulation.
(3)
Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC) designations.
Do not remove the protective debris strip until after the controller and all other equipment
in the panel near the controller are mounted and wiring is complete. Once wiring is
complete, remove protective debris strip. Failure to remove strip before operating can
cause overheating.
Electrostatic discharge can damage semiconductor devices inside the controller. Do not
touch the connector pins or other sensitive areas.
