Installation Disconnect power prior to installation.
Reinstall any covers that are displaced during the installation before powering the unit.
Mount the meter in an appropriate electrical enclosure near equipment to be monitored.
Do not install on the load side of a Variable Frequency Drive (VFD), aka Variable Speed Drive (VSD)
or Adjustable Frequency Drive (AFD).
The meter can be mounted in two ways: on standard 35 mm DIN rail or screw-mounted to the interior surface of the enclosure.
A. DIN Rail Mounting
1. Attach the mounting clips to the underside of the housing by sliding them into the slots from the inside. The stopping pegs
must face the housing, and the outside edge of the clip must be ush with the outside edge of the housing.
2. Snap the clips onto the DIN rail. See the diagram of the underside of the housing (below).
Clip flush with
outside edge
Snap onto
DIN rail
Insert clips from inside
3. To reduce horizontal shifting across the DIN rail, use two Veris AV02 end stop clips.
B. Screw Mounting
1. Attach the mounting clips to the underside of the housing by sliding them into the slots from the outside. The stopping pegs
must face the housing, and the screw hole must be exposed on the outside of the housing.
2. Use three #8 screws (not supplied) to mount the meter to the inside of the enclosure. See the diagram of the underside of the
housing (below).

The meter has a number of dierent possible system wiring congurations (see Wiring Diagrams section). To congure the meter,
set the System Type via the User Interface, LON variable cpSystemType. The System Type tells the meter which of its current and
voltage inputs are valid, which are to be ignored, and whether neutral is connected. Setting the correct System Type prevents
unwanted energy accumulation on unused inputs, selects the formula to calculate the Theoretical Maximum System Power, and
determines which phase loss algorithm is to be used. The phase loss algorithm is congured as a percentage of the Line-to-Line
System Voltage (except when in System Type 10) and also calculates the expected Line to Neutral voltages for system types that
have Neutral (12 & 40).
Values that are not valid in a particular System Type display as “----” on the User Interface or as QNAN in the LON variables.

Fuse Recommendations
Keep the fuses close to the power source (obey local and national code requirements).
For selecting fuses and circuit breakers, use the following criteria:
• Select current interrupt capacity based on the installation category and fault current capability.
• Select over-current protection with a time delay.
• Select a voltage rating sucient for the input voltage applied.
• Provide overcurrent protection and disconnecting means to protect the wiring. For AC installations, use Veris AH02,
AH03, AH04, or equivalent. For DC installations, provide external circuit protection. Suggested: 0.5 A, time delay fuses.
• The earth connection (G) is required for electromagnetic compatibility (EMC) and is not a protective earth ground.

Set Phase Loss:
VOLTS - Phase Loss Voltage: Phase Loss Voltage Threshold in
percent of system voltage. Any phase (as configured by the System

For example, with the system type set to 40 (3L+N) and the System
voltage set to 480V L-L, the L-N voltage for each phase is 277V.
When this threshold is set to 10%, if any phase drops to less than 10%
of 277V (less than 27.7V), or if any L-L voltage drops to less than 10% of
480V (less than 48V), the corresponding phase loss alarm activates.
IMBAL - Phase Loss Imbalance: Phase Loss Imbalance Threshold in
percent is the fractional difference in Line to Line voltages above which
Phase Loss Alarm is on. For a 3-phase Y(3+N) system (type 40), both
Line to Neutral and Line to Line voltages are tested. In a 3-phase delta
system (type 31), only the Line to Line voltages are examined. In a single
split-phase (2+N) system (type 12), only the Line to Neutral voltages are
compared. For system types 1+N (10) and 2 (11), imbalance is not tested.

E50F2A, E50F5A Installation Guide
The following resources are available at the Veris website, www.veris.com under Design Resources -> Protocol Info -> LonWorks.
Plugin
The E50 LNS plugin oers the simplest method to congure the E50FxA meter. The plugin displays all of the conguration options
and installs the Veris Resource File Set and device template. The LNS Network Operating System and a plugin Director (to launch
the plugin, such as LonMaker) are both required to run the plugin.
Device Interface Files
The E50 device interface les (.XIF, .XFB in binary form) are required to properly commission a device. Creating a device template
from these les allows the network to correctly name the network variables and conguration properties. Download and save the
device interface les to C:\LonWorks\import\Veris Industries\. Alternatively, the E50 LNS Plugin installs these les automatically
(no need to download the les separately).
Resource File Set
All of the meter’s network variables (except nvoLoggedData) use standard network variable types (SNVTs). However, the
conguration properties to set the meter installation details (CT size, system type, system voltage, etc.) are user-dened
conguration properties (UCPTs). The Veris website includes a manufacturer-scoped resource le set to recognize these types, but
they are not necessarily required. Commissioning and conguring options are explained below, and the need for the resource les
depends on the situation and user preference. The E50 LNS Plugin automatically installs the Veris Resource File Set (no need to
download these les separately). Note: If using resource les, install them before importing the device template into a network.
Resources Available for
Downloading
The following instructions are written for the Veris E50 LNS Plugin using LonMaker. If using a dierent integration tool, replace the
specic steps that have actions in LonMaker with equivalent procedures for the integration tool in use (see documentation for the
tool).
Installation Instructions
1. Download the “Veris E50 LNS Plugin Vx.x Installer.zip le from the Veris website, found under Design Resources->Protocol
Info->LonWorks.
2. Extract all les from the zip.
3. Double click the setup.exe le to start the installer. If installing on Windows 7 or Windows Vista, when the User Access Control
dialog appears, click “Allow” to give the installer administrative privileges.
4. Install the Microsoft .NET Framework 2.0 (or above) at this point. Follow the prompts, and then the plugin installer will begin.
5. Click Next and select a folder to install the plugin to. It is recommended to keep the default of LonWorks\apps\Veris Industries\
Veris E50 LNS Plugin\ based on guidelines from Echelon documentation, but changing the installation path is allowed.
6. Click Next twice to conrm the installation, then click close when installation is complete.
Installation Details
The Veris E50 LNS Plugin Installer both installs and registers the plugin, while also copying support les to default locations.
Device resource les are placed in the “[local drive]\LonWorks\Types\User\Veris Industries\E50Meters\” folder. These resource
les are automatically added to the LNS Resource File Catalog. Any existing resource les for the E50 meters are removed from
the catalog and the computer. The device template (VerisE50.XIF and VerisE50.XFB) and application image (VerisE50.APB and
VerisE50.NXE) les are copied to the “[local drive]\LonWorks\import\Veris Industries\” folder. When the plugin is registered with
a network for the rst time, if the E50 device template has not already been imported, the plugin automatically adds it to the
network under the template name “VerisE50.”

E50F2A, E50F5A Installation Guide
Registration Instructions
The plugin installer registered the plugin globally, but as a system level plugin, it must be registered separately for each network
that requires it. Registration can be accomplished either while opening a network or after a network is opened. Instructions here
are for the latter method.
1. Open the LonMaker network where the plugin is to be registered.
2. Select the LonMaker menu (on the toolbar in Visio 2003; under the Add-ins toolbar in Visio 2010). From the drop-down list,
select “Plugins,” and then “Register Plugins…”
3. Select the “Veris E50 Device Plug-in” entry from the plugin list and press the “Register” button.
4. Press the “Okay” button.
Device Creation Instructions
Creating an E50 device in LonMaker is no dierent than creating any other device.
1. Drag a “Device” from the LonMaker Basic Shapes stencil or other stencil to the drawing. This opens the new device wizard.
2. Click the “Commission device” checkbox unless the network is being created ONet (“Engineered” mode), or if there is any
other reason to delay commissioning.
3. From the Device Template section, choose the “VerisE50” template from the drop-down list (the plugin added the template to
the network when registering).
4. Finish customizing using the wizard prompts and press “Finish”.
5. If commissioning was selected, press the service pin on the meter.
Device Configuration Instructions
The plugin has two tabs useful for conguring the device. The “Meter Setup” tab includes details related to the installation (CT
size, system type, system voltage, etc.), and other settings related to the demand interval and alarm conguration. The second
tab for conguration of the device is the “Propagation Settings” tab, which includes conguration properties that control
propagation (heartbeat, throttle, etc.). Settings can be written to both the database and the device if the device is online (or soft
oine), commissioned, and the LonMaker mode is OnNet. Otherwise the settings can only be written to the database. There is
some behavior to be noted if changes are made while the device is soft oine. Please read the “Important Information When
Conguring While Soft Oine” section below.
1. Right click on the E50 device and select “congure” from the context menu. This brings up the “Meter Setup” tab of the plugin.
2. To get the current setting from the meter or the database, press the “GET PRESENT SETTINGS” button. If the conguration
properties on the device do not match the database, a prompt appears to choose which values to load.
3. Make the necessary changes to the Installation Details and Other Settings. Note that the Demand Subinterval Length is also the
logging interval for E50F5 meters, so it can be congured at this point (see the “Conguring the Data Log” section below for a
description of the meter’s data logging capabilities).
4. Press “APPLY SETTINGS.” If the device is online (or soft oine), commissioned, and the LonMaker mode is OnNet, the
conguration property settings are applied to both the network database and the device. If, however, the above conditions
are not met, the conguration property settings are only written to the database. A dialog box appears when the write is
nished, stating where the values were written to. If values were not written to the device (database only), the device must be
resynchronized to the database at a later time. See the “Conguration Property Resynchronization” section below.
5. Switch to the “Propagation Settings” tab of the plugin (tab control is at the top of the plugin).
6. To get the current setting from the meter or the database, press the “GET PRESENT SETTINGS” button. If the conguration
properties on the device do not match the database, a prompt will appear to choose which values to load.

7. Make the necessary changes to the propagation settings and press “APPLY SETTINGS.” If the device is online (or soft oine),
commissioned, and the LonMaker mode is OnNet, the conguration property settings are applied to both the network
database and the device. If, however, the above conditions are not met, the conguration property settings are written to the
database only. A dialog box appears when the write is nished, stating where the values were written to. If values were not
written to the device (database only), the device must be resynchronized to the database at a later time. See the “Conguration
Property Resynchronization” section below.
Saving/Loading Configuration Templates
Values on the “Meter Setup” and “Propagation Settings” tabs can be saved separately to template (.xml) les for easy recovery at
a later time or for use with another E50 device. When either of these tabs is selected, a “Template” menu appears highlighted in
yellow on the menu bar.
Save to Template (.xml) File
1. Select “Template”->”Save To Template”. If all the values are lled in and are acceptable values for an E50 (range checking is
done here), a “Save As” le window appears.
2. Navigate to the desired folder and create a name in the “File Name” eld (or select an existing .xml le).
3. Press the “Save” button.
Load From Template (.xml) File
1. Select “Template”->“Load From Template”.
2. Navigate to the folder where the .xml le exists and select the le.
3. Press the “Open” button.
Formatting Power Correctly
LonMark Resource Files before version 13.04 set the default format in the U.S. for network variables of the type SNVT_power_f as
units of Btu/hr. This formatting results in power values being reported about 3.4 times higher than they actually are in Watts. The
plugin always displays correct values in Watts, however, since it uses raw values, not formatted values.
There are a few ways to resolve this formatting issue, described below. Upgrading the LonMark Resource Files is the least tedious
method, but may require checking the rest of the network to verify that no issues have been introduced by the other changes
LonMark has made to the resource les.
Update the LonMark Resource Files
1. Uninstall the current LonMark Resource Files by opening the “Add or Remove Programs” dialog in Windows, selecting the
“LonMark Resource Files 13.xx” and pressing “Remove.”
2. In a web browser, navigate to www.LonMark.org, “Technical Resources” (from the menu bar at top) ->”Resource Files”->”Start
SNVT/SCPT Download…”
3. Follow the prompts to complete the resource le installation.
4. Power values are now formatted in Watts.
Manually Update the Power Network Variables
1. In LonMaker, right click on the E50 device and select “Plugins”-> “Echelon AppDevice Browse”.
2. Right click on the row for a power network variable and select “Change Format” from the context menu (can alternatively press
Ctrl+A when the line is selected).
3. From the “Select Network Variable Format” dialog, select SNVT_power_f#SI (not #US) and press OK.
4. Repeat steps 2 and 3 for each power network variable.
5. If any of the power network variables are bound (as opposed to polled), repeat steps 2 and 3 for the input network variables
of other devices the meter is bound to. The format of the input network variable on the other end determines the format that
device receives, not the formatting of the E50 meter’s output network variable.

Important Information When Configuring While Soft Offline
When a device is commissioned but is soft oine (green crosshatch in LonMaker), application code does not execute. The device
only processes network management commands. The device can be successfully congured soft oine, though. The conguration
property values are physically stored on the device, and processed and applied when the device is brought online. This does mean,
though, that setup values on the screen of the device do not reect new values applied using the plugin while soft oine until the
meter is brought online.
Configuration Property Resynchronization
If the device was congured using the plugin and values were saved to only the database for any reason (ONet, device not
commissioned, etc.), the conguration properties in the database must be downloaded to the device at some point. If the device
has not yet been commissioned, this synchronization can be performed while commissioning the device. Otherwise follow the
second procedure.
Synchronization While Commissioning
1. Right-click on the device in LonMaker and select “Commissioning”-> “Commission…” from the context menu.
2. For the “Source of CP Values”, select “LNS database.” Press “Finish” to complete commissioning.
Synchronization While Device is Commissioned and Online
1. Right-click on the device in LonMaker, and select “Commissioning”-> “Resync CPs…” from the context menu.
2. Select “Download current values to device” as the operation.
3. Press the “OK” button.
Viewing Meter Values
If the device is online and the network is attached, present values from the meter such as power and energy can be viewed using
the plugin by right-clicking on the device and selecting “Browse…” from the context menu. The plugin loads with the “Network
Variables” tab selected. Four buttons on the left alternate among viewing the instantaneous, demand, energy, and status pages.
Polling defaults to every 5 seconds, but only the values shown on the screen at any one time are polled (no polling while on
the “METER SETUP” and “PROPAGATION SETTING” tabs), and with a small delay between values to keep the network load to a
maximum of about 10 packets per second during each poll. The polling rate can also be changed using the drop-down list on the
left.
Restarting Polling
Polling status is shown in the bottom right corner of the plugin. Polling is disabled in the following cases:
• LonMaker Management Mode is ONet.
• Device is not commissioned.
• Device is not Online.
• Device is not responsive or fails tests.
• An exception occurs while polling device values.
After resolving the issue, restart polling in one of two ways:
1. Close the plugin and reopen it. The condition of the device and network are tested, and polling begins if everything is
normal.
2. From the menu bar, select File ->”Attempt Polling Restart.” The condition of the device and network are retested, and
polling begins if everything is normal.
