Notices
FCC
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to part 15 of the FCC rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no
guarantee that the interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to
try to correct the interference by one or more of the following measures:
The user is cautioned that any changes or modifications not expressly approved
by Schneider Electric could void the user’s authority to operate the equipment.
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment to an outlet on a circuit different from that to which the
receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
This digital apparatus complies with CAN ICES-3 (B) /NMB-3(B).

About this manual
This manual discusses features of the iEM3100 / iEM3200 / iEM3300 series
energy meters and is intended for use by designers, system builders and
maintenance technicians with an understanding of electrical distribution systems
and monitoring devices.
Document scope
Throughout the manual, the term “meter / device” refers to all models of the
iEM3100 / iEM3200 / iEM3300 series. All differences between the models, such
as a feature specific to one model, are indicated with the appropriate model
number or description.
This manual does not provide configuration information for advanced features
where an expert user would perform advanced configuration. It also does not
include instructions on how to incorporate meter data or perform meter
configuration using energy management systems or software, other than ION
Setup. ION Setup is a free configuration tool available for download from
www.se.com.
Please contact your local Schneider Electric representative to learn what
additional training opportunities are available regarding the iEM3100 / iEM3200 /
iEM3300 series energy meters.

Safety precautions
Installation, wiring, testing and service must be performed in accordance with all
local and national electrical codes.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Apply appropriate Personal Protective Equipment (PPE) and follow safe
electrical work practices. See NFPA 70E, CSA Z462 or other local
standards.
• Turn off all power supplying this device and the equipment in which it is
installed before working on or in the equipment.
• Always use a properly rated voltage sensing device to confirm that all power
is off.
• Assume communications and I/O wiring are hazardous live until determined
otherwise.

communications and I/O wiring connected to multiple devices.
WARNING
UNINTENDED OPERATION
Do not use this device for critical control or protection of persons, animals,
property or equipment.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
WARNING
INACCURATE DATA RESULTS
• Do not rely solely on data displayed on the display or in software to
determine if this device is functioning correctly or complying with all
applicable standards.

Programmable digital output
Allows you to monitor energy
consumption and production
Can be programmed to:
• Count pulses from other
meters (gas, water, etc.)
• Monitor an external status
• Reset the partial energy

new period of
accumulation
Can be programmed to:
• Be an active energy (kWh)
pulse output, with a
configurable pulse weight
• Alarm on a power
overload at a configurable
pickup setpoint
Manage energy consumption
and make informed investment
to reduce your energy bill or
penalties (for example, installing
capacitor banks)
This allows for monitoring of:
• WAGES
• Intrusion (for example,
doors opening) or
equipment status
• Energy usage
This allows you to:
• Collect pulses from the
meter with a Smartlink
system, PLC or any basic
acquisition system
• Monitor power levels at a
detailed level and to help
detect an overload before
the circuit breaker trips

Hardware and installation
Overview
This section provides supplemental information to help mount and install your
meter. It is intended to be used in conjunction with the installation sheet that ships
in the box with your meter. See your device’s installation sheet for information
related to installation, such as dimensions, mounting and wiring instructions.
Safety precautions
Installation, wiring, testing and service must be performed in accordance with all
local and national electrical codes.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Apply appropriate Personal Protective Equipment (PPE) and follow safe
electrical work practices. See NFPA 70E, CSA Z462 or other local
standards.
• Turn off all power supplying this device and the equipment in which it is
installed before working on or in the equipment.
• Always use a properly rated voltage sensing device to confirm that all power
is off.
• Replace all devices, doors and covers before turning on power to this
equipment.
• Do not exceed the maximum ratings of this device.
• Do not touch the current terminal when the meter is energized.
Failure to follow these instructions will result in death or serious injury.
Meter sealing points
All meters have sealing covers and sealing points to help prevent access to inputs
and outputs and current and voltage connections.
Input, output and communications wiring considerations
The pulse output is compatible with S0 format, and the programmable digital
output is compatible with S0 format when configured as a pulse output.
The digital input and output are electrically independent.
The digital output is polarity-independent.
