DESCRIPTION
The 420E2 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 interruption of service. The 420E2 series is designed to protect 4-20mA analog control loops from differential and common mode transients. Terminals 1 and 2 are designed as the line pairs for both the line and equipment side of the protector. A transient voltage suppressor is internally connected across each line pair for differential mode protection. Each line pair is referenced to ground. This product can also be used on telephone, signal/data lines, security timing and control interface circuits. 05053 420E
205053.R4 7/04 www.protekdevices.com DEVICE CHARACTERISTICS INSTALLATION INSTRUCTIONS There are two (2) terminals on the LINE SIDE and three (3) wires on the EQUIPMENT SIDE of this surge protection device (SPD). 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.
