WARNING! During normal operation of the meter
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.
IMPORTANT! All wiring is done with the cover open, as shown
on the left. The front cover support fits into its base. Make sure
the support is up before closing the front cover.
Select wiring diagram to meet your application. See User Manual for additional wiring diagrams.
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.
