Low Voltage Directive
This product is tested to meet Council Directive 2006/95/ECLow Voltage, by
applying the safety requirements of EN 61131-2 Programmable Controllers, Part
2 - Equipment Requirements and Tests.
For specific information required by EN 61131-2, 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
• Guidelines for Handling Lithium Batteries, publication AG-5.4
• Automation Systems Catalog, publication B115
Installation Considerations
Most applications require installation in an industrial enclosure (Pollution
Degree 2
(1)
) to reduce the effects of electrical interference (Over Voltage
Category II
(2)
) 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
.
(1)
Pollution Degree 2 is an environment where normally only non-conductive pollution occurs except that
occasionally temporary conductivity caused by condensation shall be expected.
(2)
Overvoltage 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 products insulation.
ATTENTION: Electrostatic discharge can damage semiconductor
devices inside the controller. Do not touch the connector pins or
other sensitive areas.
ATTENTION: Vertical mounting of the controller is not supported
due to heat build-up considerations.
