Install protectors on all data communication and signal lines that enter or leave each building.All protectors must be installed via the ESP KE10 earth bar. Identify the lines requiring protection and clip the ESP KE10 on to the disconnection modules 'earth points. Plug the protector directly into each disconnection module requiring protection (ensuring the correct orientation) for a series connection.
Having pushed the ESP KE10 earth baron to the disconnection modules' earth points,firmly push an ESP KS06 (or ESP KS15,ESP KS30 or ESP KS50) into each line/pair requiring protection
If the protector's ratings are exceeded, it will sacrifice itself and fail short circuit, taking the line out of commission. In addition to indicating that the protector needs replacing, this will also prevent subsequent transients from damaging the equipment.
1 Nominal voltage (DC or AC peak) measured at <200µA
for ESP KS06 and at 5µA for ESP KS15, ESP KS30 and ESP KS50.
2 Maximum working voltage (DC or AC peak) measured at <10mA
for ESP KS06, at 1mA for ESP KS15 and ESP KS30, and at 5µA
for ESP KS50.
