Installation

High-performance photoelectric relay for public lighting management. It is ideal for energy management and can be used to monitor and control luminaires, allowing for efficient load management, identification of network faults, and reduction of energy losses.

The electrical connection of the Exatron LEIP4203 Remote Management Relay must be made using a 7-wire socket (not included with the product) that meets NBR 5123 and ANSI C136.41 standards.

The relay must be manually inserted into the socket after the electrical connection to the light fixture. No special tools are required for installing and/or removing the LEIP4203 photoelectric relay from the socket; it must be done manually.
