Installation Instructions:
(1) surge special circuit breaker or a fuse or circuit breaker must be installed at the front end of the surge protector to prevent the damage of the switching SPD and its lines caused by the power frequency continuous current caused by lightning strike, and to prevent the line fault caused by the increase of leakage current caused by the aging of the voltage limiting devices.
(2) The surge protector must be installed by a professional, and the power supply should be disconnected during installation. Connect the ground terminal first, then connect the other lines.
(3) once the surge protector is installed, do not change the installation position and wiring mode of the product at will, otherwise it will affect the function of the lightning protection system.
Usage:
System voltage limiting surge protector, suitable for installation in 220V/380V(50/60Hz) or 230V/400V(50/60Hz) low voltage power supply and distribution system, It is usually installed in the lightning protection zone LPZ0, LPZ1 or LPZ1, LPZ2, computer room, monitoring machine room, fire fighting machine room, telephone machine room, office and home building power distribution machine room and other weak current machine room. It is designed to protect low-voltage electrical devices from inducted lightning strike and surge harm. This product has the advanced structure design, the high quality material device, the reliable manufacturing process, the excellent safety performance, provides the omni-directional lightning protection for the electrical equipment.
