5. The conditions of Safe usage for IECEx/ATEX (Zone2):
• Provisions shall be made to provide the transient protection to
be set at a level not exceeding 140% of the peak rated voltage.
• These devices shall be mounted in a suitable tool-accessible
ATEX/IECEx Certified enclosure rated to at least IP54 as defined
in EN/IEC 60529 and Pollution Degree 2 as defined in EN/IEC
60664-1, and used within their rated electrical and
environmental ratings.
6. The conditions of safe usage for other environments
• These products must be mounted in an IP54 enclosure.
• Install in an area of pollution degree 2 or less.
• Use a conductor wire of size 0.2 mm² or greater.
• Input Terminal Block (JP3, JP4) - Rated 300 V/12 A, solder on
the board, mating with plug-half connector suitable for 28-12
AWG (Sol, Str) wire size, torque value 4.5-5.0 lb-in. The
plughalf connection has a latching mechanism.
