Additional conditions concerning the safety of connection to telecommunication networks:

• The unit must be earthed prior to connection to telecommunication networks.

• The signal ground of the SELV circuits is connected at the factory to the protective earth.
Interrupting this connection may invalidate the safety of the connection to unprotected
telecommunication networks in certain locations where permanent excessive voltages are
present on the lines.

• In order to comply with the requirements set out in EN 60950 for TNV-3 circuits, the maximum

phantom supply voltage must not exceed 120 VDC. The remote power feeding supply must be
floating and must comply with the requirements for TNV-3 circuits.
• DC powered units must be powered from EN 60950 or UL-1950 approved power source. In
order to avoid a fire hazard, a suitable fuse or circuit breaker must be installed on the
non-earthed DC line.

accordance with the instruction manual, may cause harmful interference to the radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case
the user will be required to correct the interference at his own expense.

Warning per EN 55022

This is a Class A product. In a domestic environment, this product may cause radio interference, in
which case the user may be required to take adequate measures.

LRS-PS-FEED Output Voltage

The output voltage of the LRS-PS-FEED exceeds the limits of TNV-3 circuits. In the event of uncertainty
about the regulatory status of connecting such voltages to leased lines provided by certain service
providers, consult with a safety engineer.
