3-2 Installation and Wiring
Low Voltage Directive
This product is tested to meet Council Directive 73/23/EEC Low
Voltage, by applying the safety requirements of EN 61131-2
Programmable Controllers, Part 2 – Equipment Requirements and
Tests.
For specific information required by EN61131-2, see the appropriate
sections in this publication, as well as the following Allen-Bradley
publications:
•
Industrial Automation, Wiring and Grounding Guidelines for
Noise Immunity, publication 1770-4.1
•
Automation Systems Catalog, publication B113
Power Requirements The module receives its power through the bus interface from the +5V
dc/+24V dc system power supply.
The maximum current drawn by the module is shown in the table
below.
General Considerations to
Avoid Electrostatic Damage Compact I/O is 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 to circuits not exceeding Over Voltage Category II
(2)
(IEC 60664-1).

(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.
