dEsCRiPTiON
The 420E series is a two stage transient voltage protector providing primary and secondary protection against lightning, inductive switching and electrostatic discharge (ESD) transient threats. The first stage diverts the transient current through the ground terminal return path and the second stage clamps the voltage to a safe level without inter- ruption of service. The 420E series is designed to protect 4-20mA analog control loops from differential (line to line) and common mode (line to ground) transients. Terminals 1 and 2 are designated as line pairs for both the line and the equipment side of the protector. A transient voltage suppressor is internally connected across each line pair for differential mode protec- tion. Each line pair is referenced to ground. This product can also be used on telephone, signal/data lines, security, timing and control interface circuits.

The Ground lead is considered ground for both the input terminal and the equipment wire connections. For the best results, the ground wire should be connected to a low impedance ground or the green wire AC power ground. It is recommended that a #14 standard wire be used for this connection. Field (current) loops or incoming signal/data lines are to be cut or disconnected from the equipment to insert the SPD. The liNE sidE terminals of the protector are to be connected to the field loop wires. The EQuiPMENT sidE of the protector is connected to the equipment/controller, etc. The location of the protector should be as close to the equipment requiring protection.
