dangerous voltages flow through many parts of the meter,
including Terminals and any connected CTs and PTs, all I/O
modules and their circuits. All Primary and Secondary
circuits can, at times, produce lethal voltages and currents. Avoid contact with any current-carrying surfaces. Before performing ANY work
on the EM-3000 Series meter, make sure the meter is powered
down and ALL circuits are de-energized. AVERTISSEMENT! Pen-
dant le fonctionnement normal du compteur EM-3000 Series des tensions dangereuses suivant de nombreuses pièces, notamment, les
bornes et tous les transformateurs de courant branchés, les transformateurs de tension, toutes les sorties, les entrées et leurs circuits. Tous les
circuits secondaires et primaires peuvent parfois produire des tensions
de létal et des courants. Évitez le contact avec les surfaces sous tensions. Avant de faire un travail dans le compteur, assurez-vous
d'éteindre l'alimentation et de mettre tous les circuits branchés
hors tension.
NOTE: Jumper 2 (JP2)
must be set for either
RS485 or Ethernet commu nication (see figures on the
left for location of JP2 and
settings). Put the jumper
on positions 2 and 3 for
LAN (Ethernet) communi cation, or on 1 and 2 for
RS485 communication.
