Important safety notes for telephony connections

  • Allow only qualified technical personnel to install this board and its associated telephone wiring.

  • Make sure the PC chassis is grounded through the power cord or by other means before connecting the telephone line.

  • If your system requires an external power supply, make sure it is grounded through the power cord or by other means.

  • Never install telephone wiring during a lightning storm.

  • Never install telephone jacks in wet locations.

  • Telephone companies provide primary lightning protection for their telephone lines. However, if a site connects to private lines that leave the building, make sure that external protection is provided.
