EMC Environmental Conditions for Products Installed in the European Union

This section applies to products to be installed in the European Union.
The equipment is intended to operate under the following environmental conditions with respect to
EMC:
In addition, if equipment is operated in a domestic environment, interference could occur.

Installation Guidelines

When determining where to place the switch, observe these guidelines.

Environment and Enclosure Guidelines:

Review these environmental and enclosure guidelines before installation:

Other Guidelines

These are other installation guidelines:
A separate defined location under the user's control.
Earthing and bonding shall meet the requirements of ETS 300 253 or CCITT K27.
AC-power distribution shall be one of the following types, where applicable: TN-S and TN-C as
defined in IEC 364-3.
This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage
Category II applications (as defined in IEC publication 60664-1), at altitudes up to 9842 ft (3 km)
without derating.
This equipment is considered Group 1, Class A industrial equipment, according to IEC/CISPR
Publication 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. It must be mounted within an enclosure that is
suitably designed for those specific environmental conditions that will be present and appropriately
designed to prevent personal injury resulting from accessibility to live parts. The enclosure must
have suitable flame-retardant properties to prevent or minimize the spread of flame, complying with
a flame-spread rating of 5VA, V2, V1, V0 (or equivalent) if nonmetallic. The interior of the
enclosure must be accessible only by the use of a tool. Subsequent sections of this publication might
contain additional information regarding specific enclosure-type ratings that are required to comply
with certain product safety certifications.
The equipment should be mounted in a suitable enclosure rated to at least IP54 as defined in
EN60529 and Pollution Degree 2 as defined in IEC 60664-1 and used within their rated electrical
and environmental ratings.
Provision should be made, either in the apparatus or external to the apparatus, to prevent the rated
voltage from being exceeded by transient disturbances of more than 40 percent.
