NOTICE
Damage due to overheating
You must comply with all the instructions regarding the installation site and mounting
position. Otherwise the device may malfunction or incur permanent damage as a result of
overheating.
Pollution degree
PN/J1939 LINK is designed for Pollution Degree 2. Pollution degree 2 according to the
EN 50178 standard is non-conductive contamination in the normal case which can briefly
become conductive as a result of condensation when the device is not in operation.
Contamination of conductive parts by dust, moisture and air pollution can lead to operational
errors and electrical faults in PN/J1939 LINK.
Degree of protection
The enclosure of the PN/J1939 LINK has IP20 degree of protection according to IEC 60529.
PN/J1939 LINK is classified as "open type" or "open equipment" according to
UL 61010-2-201 or IEC 61010-2-201.
If PN/J1939 LINK is located in an area where contamination of conductive parts can occur,
PN/J1939 LINK must be protected by an enclosure with the appropriate degree of protection.
IP54 is a protection class that is generally used for electronic systems in heavily polluted
environments and may be suitable for your application.
