Lightning striking the power grid may cause electric shocks. SELV (Safety Extra Low Voltage) Compliance Safety status of input/output connections comply with

SELV requirements.
Warning: To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to teledevice network voltage (TNV) circuits. LAN ports contain SELV circuits, and PSTN ports contain TNV circuits. Some LAN and PSTN ports both use RJ-45 (8P8C)connectors. Use caution when connecting cables.
