ELPRO 450U-E Installation guide

  • Hello! I'm your chat assistant. I've reviewed the Installation Guide for the ELPRO 450U-E Wireless Ethernet Modem and Device Server. This document provides detailed instructions on how to properly connect and install the device including power supply wiring, RS-485 and RS-232 connections and analog/digital I/O. I'm ready to answer your questions about it.
  • What types of locations is this equipment suitable for?
    What are the voltage requirements for all connections?
    Where should the M4 GND screw be connected?
    What should be considered if installing in a hazardous environment?
