IEEE 1000-4-5 and ITU-TK20 are the recognized standards for top quality surge protectors.
The FL485 protects RS422 and RS485 ports from damage caused by large voltage peaks from lightning and other power problems. The Surge Protector uses 600W Transient Voltage Suppressors to protect data lines. It has screw terminals at both ends for easy installation. The Transient Voltage Suppressors are connected between the ground screw and pins 1 and 2. The FL485 is placed inline, between the data cable and the RS-232 port, as close to the protected port as possible. The FL485 will suppress any voltage levels above 15 volts without affecting the normal data transmission.The ground screw must be connected to earth ground. A minimum of 12 AWG copper wire is recommended. If this device is not properly grounded it will not protect the data lines.
