Even sheet lightning between clouds, which accounts for more than half of all lightning discharges, can generate electromagnetic fields strong enough to induce voltages of many thousands of volts in cables. The OxyGuard Lightning Protection Unit is designed to protect OxyGuard multichannel central units from damage should such voltages occur in the probe leads. Individual probe cables are connected to the OxyGuard LPU, which is then connected to the central unit with a multi-core cable. The OxyGuard LPU must be connected to an effective earth connection, which should also be used to earth the OxyGuard unit. Mains power and other connections should also be protected using suitable equipment, approved by local authourities where relevant.
Connection is made as indicated overleaf.
Please contact OxyGuard if you use OxyGuard equipment in areas where lightning strikes are frequent. This cable is 3 meters long, and should not be extended.
