FCC PART 15 INFORMATION
NOTE: This equipment has been tested by the manufacturer and found
to comply with the limits for a class B digital device, pursuant to part
15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is
operated in a residential environment. This equipment generates, uses,
and can radiate radio frequency energy and, if not installed and used
in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in
a residential area may cause harmful interference in which case the
user will be required to correct the interference at his own expense.
Modifications to this product without the express authorization of
Veris Industries nullify this statement.

For use in a Pollution Degree 2 or better environment only. A Pollution Degree 2 environment must
control conductive pollution and the possibility of condensation or high humidity. Consider the
enclosure, the correct use of ventilation, thermal properties of the equipment, and the relationship
with the environment. Installation category: CAT II or CAT III
Provide a disconnect device to disconnect the meter from the supply source. Place this device
in close proximity to the equipment and within easy reach of the operator, and mark it as the
disconnecting device. The disconnecting device shall meet the relevant requirements of IEC 60947-
1 and IEC 60947-3 and shall be suitable for the application. In the US and Canada, disconnecting
fuse holders can be used. Provide overcurrent protection and disconecting device for supply
conductors with approved current limiting devices suitable for protecting the wiring. If the
equipment is used in a manner not specified by the manufacturer, the protection provided by the
device may be impaired.
