* See Configuration section for details.
**The E31 must be installed in an appropriate electrical and fire enclosure per local regulations. If Veris E31 products are used in
installations with circuits higher than the product ratings, the circuits must be kept segregated per UL508A Sec. 17.5. Note: E31
internal circuitry (cables and CTs) are not circuits as defined by UL508A, as they do not extend beyond the E31 itself without further
safety/fire isolation.
*** A Pollution Degree 2 environment must control conductive pollution and the possibility of condensation or high humidity.
Consideration must be given to the enclosure, the correct use of ventilation, thermal properties of the equipment and the
relationship with the environment.
