International:

• IEC 61326-1: Basic electromagnetic environment
• CISPR 11: Group 1, Class A
  • Group 1: Equipment has intentionally generated and/or uses conductively-coupled radiofrequency energy that is necessary for the internal function of the equipment itself.
  • Class A: Equipment is suitable for use in all establishments other than domestic and those directly connected to a low-voltage power supply network that supplies buildings used for domestic purposes. There may be potential difficulties in ensuring electromagnetic compatibility in other environments due to conducted and radiated disturbances.

    Emissions that exceed the levels required by CISPR 11 can occur when the equipment is connected to a test object.

Korea (KCC):

• Class A: Equipment meets requirements for industrial electromagnetic wave equipment and the seller or user should take notice of it. This equipment is intended for use in business environments and not to be used in homes.

USA (FCC):

• 47 CFR 15 subpart B. This product is considered an exempt device per clause 15.103.
