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 this
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 disconnecting 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.
