Your meter in an energy management system
In an energy management system the 9410 meter collects and aggregates data.
This data is used to perform non-critical control or is shared with other equipment in
the energy management system. Data from the meter can be used by energy
management software to help with energy cost management, trending and forecasting,
network management, power quality analysis, and more.
The meter is user-configurable to adapt to many situations. Communications allow
data to be shared simultaneously across multiple networks, built-in and optional I/O
provides monitoring and non-critical control capabilities, and a variety of display and
analysis tools can be used to monitor your system.
The following graphic outlines your meter’s capabilities in an energy management
system.
10 7EN05-0336-01

Meter overview 9410 series
Measured parameters
Energy
Your meter provides bi-directional 4-quadrant energy metering.
Your meter provides active, reactive and apparent energy values.
• kWh, kVARh, kVAh delivered and received
• kWh, kVARh, kVAh net (delivered - received)
• kWh, kVARh, kVAh total (delivered + received)
• Volt-squared-hours and amp-squared-hours
Energy parameters can be logged automatically on a programmed schedule.
All energy values represent the total for all three phases.
Demand
Your meter supports several demand calculation methods, including block, rolling
block, synchronized and predicted demand.
It can measure demand on any instantaneous value and record peak (maximum) and
minimum demand with time and date information.
• kW, kVAR, kVA demand
• kW, kVAR, kVA peak demand
• Amps, Volts demand
7EN05-0336-01 11

9410 series Meter overview
Instantaneous
Your meter provides one second and half-cycle measurements, per phase and totals
for many values.
• Voltage and current
• Apparent power (kVA), active power (kW) and reactive power (kVAR)
• Power factor and frequency
• Voltage and current unbalance
Harmonics
Your meter provides harmonic distortion metering, recording and real-time values for
all voltage and current inputs.
• Individual harmonics (including magnitude and phase angle) up to the 63rd
harmonic
• Total even harmonic distortion (TEHD) and total odd harmonic distortion (TOHD)
• Total harmonic distortion (THD) or total demand distortion (TDD)
• K-factor, Crest factor
Min/max recording
Your meter records new minimum and maximum data every recording interval for a
variety of values.
• Voltage and current
• kW, kVAR and kVA
• Power factor
• Frequency
• Voltage unbalance
• Plus any measured value
Power quality
Your meter measures and records voltage and current sags and swells.
Your meter also has many power quality related features.
• Disturbance direction detection: this allows the meter to analyze disturbance (sag/
swell) information to help determine the direction of the disturbance relative to the
meter.
• Setpoint learning: this allows the meter to learn the power quality characteristics of
your system, to help identify what constitutes a sag or a swell.
• COMTRADE: this allows the meter to save waveform data in COMmon format for
TRAnsient Data Exchange (COMTRADE) on its internal FTP server.
Your meter includes the following power quality compliance:
• EN50160: Your meter measures and presents statistics for determining EN50160
compliance.
• IEC 61000-4-30: Your meter complies with the IEC 61000-4-30 power quality
standard.
• IEC 62586: Your meter complies with the IEC 62586 power quality standard.
12 7EN05-0336-01

Meter overview 9410 series
Localization
The meter can be customized to use different regional settings.
Localization settings determine:
• The language used for the display and webpages
• Time, date and digit formats
• Displayed phase labels (123/ABC)
• IEEE (Institute of Electrical and Electronics Engineers) or IEC (International
Electrotechnical Commission) conventions for power, power factor and energy
You can configure your meter’s localization settings through the display or using ION
Setup.
Data display and analysis tools
Display
Use the meter’s display for local monitoring and standalone applications.
The color LCD display lets you view real-time values, events and alarms, and perform
basic device configuration. Connect a remote display to a meter without an integrated
display to view meter data and perform basic meter configuration.
Active and historical alarms
The meter’s display shows an alarm icon and the alarm LED flashes if your meter
detects an active alarm condition.
Depending on the priority of the alarm, your meter’s display also flashes. You can view
and acknowledge active alarms and historic alarms and events through the display
and software webpages. An active alarm becomes a historic alarm when the alarm
condition no longer exists.
Meter internal web server feature
Your meter’s internal web server provides quick and easy access to real-time energy
and basic power quality information without special software using an on-board web
server combined with an Ethernet port.
The built-in web pages display selected energy and power quality information through
the web-enabled device; these pages also support basic meter configuration.
Email messaging feature
You can configure your meter to automatically email information, whether notification
of a high-priority event or a regularly scheduled send of logged data, to an external
email address.
Specify the type of event that triggers an email alert, such as a power quality
disturbances or interval for logged data. Email messages from your meter are received
like any other email message.
Supported protocols
Your meter’s fundamental protocol and architecture is ION.
7EN05-0336-01 13

9410 series Meter overview
You can integrate the meter into various industry-standard networks. Data that the
meter measures can be made available to other devices using Modbus, DNP 3.0 and
SNMP as well as the MV-90 translation system. You can configure the meter to import
data from other devices on these networks. Your meter supports the IEC 61850
protocol and COMTRADE waveform data format.
Your meter also supports IPv6, DPWS and RSTP Ethernet protocols.
ION Setup device configuration tool
ION Setup is a free configuration tool for your meter that allows you to remotely
configure your meter’s features over Ethernet or serial communications.
• Use the setup screens to guide you through the process of configuring your meter.
• Use the real-time data screens to verify your meter’s configuration.
• Use the data screens to view your meter’s recorded data.
• Use the charting function to view your meter’s recorded waveforms.
You can download ION Setup from www.usa.siemens.com/pds.
See the online ION Setup help, available from www.usa.siemens.com/pds, for
instructions on connecting to your meter.

The voltage and current terminal covers help prevent tampering with the meter’s
voltage and current measurement inputs.
The terminal covers enclose the terminals, the conductor fixing screws and a length of
the external conductors and their insulation. The terminal covers are secured by
tamper-resistant meter seals.
These covers are included for meter models where sealable voltage and current
covers are required to comply with revenue or regulatory standards.
The meter terminal covers must be installed by a qualified installer.
Refer to your meter's installation sheet or the instructions that came with your terminal
covers for instructions on installing the terminal covers.
