Installation

1. Do power off when connect surge protection device to system.
2. Ground wire should be as short, straight and thick as possible to reduce the influence of distributed inductance on lightning discharge.
3. No need special maintenance. When surge protector happens fault,equipment connected to remote signal will send alarm, then power off and change new spd mould is fine.
