Environment and Enclosure Information
Review information on enclosures and environments before installing the product.
Voltage Precaution
The computers contain line voltages. Disconnect all power to the computer before you install or
remove system components.
ATTENTION: This equipment is intended for use in a Pollution Degree 2 industrial environment, in
overvoltage Category II applications (as defined in IEC 60664-1), at altitudes up to 2000 m
(6562 ft) without derating.
This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR 11.
Without appropriate precautions, there may be potential difficulties ensuring electromagnetic
compatibility in other environments due to conducted as well as radiated disturbance.
This equipment is supplied as open type equipment. UL recognized equipment must be mounted
within an enclosure that is suitably designed for those specific environmental conditions that are
present and appropriately designed to prevent personal injury resulting from accessibility to live
parts. The interior of the enclosure must be accessible only by the use of a tool. UL Listed
equipment does not need to be mounted inside another enclosure.
