Environmental
Caution The NI WSN-3291 is intended for outdoor use in most environments, but does have the
following limitation. Placing the NI WSN-3291 in direct sunlight causes the internal temperature to
rise above the outdoor ambient. NI recommends accounting for this limitation when using the
NI WSN-3291.

Understanding IP Ratings
Proper use and installation of an NI WSN-32xx device in an NI WSN-3291 outdoor IP enclosure
provides a minimum IP rating of IP65 from harsh outdoor and industrial environments. An IP rating
of IP65 protects against entry by dust particles and low pressure water jets.
The two-digit ingress protection (IP) rating is defined by the IEC 60529 standard and specifies the
degree to which the enclosures protect against the intrusion of solid particles (represented by the
first number) and water (represented by the second number).
Table 2 lists the degree of protection.
