3.6 EMC Certification
This product complies with EN61326 Electrical Equipment for Measurement, Control and
Laboratory use – EMC Requirements for Minimum Requirements and Industrial Locations.
Special caution should be taken to meet Standard EN61000-4-5: 1995 Surge Immunity if
any of the following conditions apply to the installation: The product is installed outside;
all or any part of the cable is exposed to the outside; the cable is greater than 30 meters in
length. In order to meet the Surge Immunity requirements, the following conditions must
be followed during installation:
1. Shielded cable must be used, and the shield must be tied to earth ground (not power supply
ground) on at least one end of the cable shield/drain wire. The shield must be maintained all
the way from sensor to the power supply.
2. If unshielded cable is used, an earth grounded metal conduit fitting can be used to replace the
shielded cable.
3. For a sensor with a metal body or enclosure, the body/enclosure must be grounded to earth. If
a protective metal housing is used, the metal housing should be grounded to earth
4. If a protective plastic housing is used, the housing must be able to withstand at least
2 KV from the housing to earth ground, without damaging the circuit.
