Protection against Lightning
The use of lightning protection is dependent on regulatory and end user
requirements. All of RADWIN outdoor units are designed with surge limiting
circuits to minimize the risk of damage due to lightning strikes. RADWIN
recommends the use of additional surge arrestor devices to protect the
equipment from nearby lightning strikes.
See Appendix C for detailed installation instructions of lightning protection
devices.
General
• It is recommended that installation of the outdoor unit be contracted
to a professional installer.
