DLU surge protectors are designed to protect, against surge voltages due to lightning, terminals equipment connected to industrial buses, telecom lines or datalines. These surge protectors must be installed on symmetrical DIN rail and are available for most of the transmission lines: line voltage from 6 to 170V, bitrate up to 10 Mbit/s. These products are 1-pair surge protectors and are made with DIN rail monobloc enclosure

Installation

DLU-12D3 surge protectors are connected in serial on the network.
The protected equipment must be nearby (protector/equipment distance less than 10 m long). If this rule cannot be followed, «secondary» protection must be installed near the equipment (coordinated surge protection).
The total length connection wires to network must be lower than 0.5 m in order not to increase the protection level (Up) provided by the SPD.
Wiring is made by screw connections.
The protection wire coming from the SPD must be connected to the bonding bar of the electrical panel.
Local earthing resistance must be in compliance with the electrical rules.
