Vemer Energy-400 PWR User manual

  • Hello! I'm your AI assistant. I've analyzed the user manual for the Vemer ENERGY-400 PWR, ENERGY-3x130 PWR and ENERGY-3x130 PWRi energy meters. This document provides comprehensive instructions on installation, safety warnings, technical specifications and features like visual indicators, impulse output and CT ratio configuration. I'm ready to address any questions you may have about these devices.
  • What type of systems are these energy meters designed for?
    What is the purpose of the red warning light?
    What type of output does the device have?
    What is the recommended way to change the CT ratio?
User Manual
ACTIVE ENERGY METER
Read all the instructions carefully
TheENERGY-400 and ENERGY-3x130 are electronic static devices to read active energy in
three-phasesystemsdesignedtooperateinenvironmentswithmeasurementcategoryIIIand
pollution level 2 according to EN 61010-1 standard.
SAFETY WARNINGS
To guarantee correct installation, proceed as follows:
1) The appliance should be installed by a qualified operator
2) The appliance should be installed in a panel in such a way as to guarantee that the
terminals are inaccessible after fitting
3) A protection device against over-currents should be installed in the electrical system,
upstream of the energy meter
4) Connect the instrument as shown in the alongside diagrams
5) Before touching the connector terminals make sure that the wires to be connected or
already connected to the instrument are not live
6) Touch the dip-switches only when the instrument is not powered
7) Do not power or connect the instrument if any part of it is damaged
8) The instrument must be installed and activated in compliance with current electric
system standards.
