SECTION 2: OVERVIEW
The BGS16 is a power monitoring system designed for installation on select panelboard
circuits or input feeds, high energy loads such as generators, HVAC equipment and
switchgear. The system transmits the monitoring information via a wireless mesh network to
one or more Packet Power Ethernet Gateway (“Gateway”) devices.
Supported Voltage Service Types
The BGS16 comes pre-wired for use with one of the following service types:
120V and 230-240V single-phase (L + N + ground)
208V single-phase (L + L + ground)
277V single-phase (L + N + ground)
208/120V three-phase wye (3-wire + N + ground)
208V three-phase delta (3-wire + ground)
240/120V split-phase (2-wire + N + ground)
415/240V three-phase wye (3-wire + N + ground)
480/277V three-phase wye (3-wire + N + ground)
Ensure that the type of voltage service that is present in the equipment you are monitoring
matches the type indicated on the label of the BGS16. The BGS16 cannot be used on 480V
equipment if access to N is not present nor on 600/347V circuits. The BGS16 is powered
from the voltage source it is monitoring.
Current Transformers
The BGS16 is preconfigured for use with split core CTs with rated amperage of 15A to
4000A and 333mV output or Rogowski coil sensors supporting 100A to 4000A. Split core
CTs can be safely used on circuits up to 120% of their nominal rating (for example a 100A
CT can be used on circuits up to 120A).
Use of the CTs on circuits with greater than maximum load will result in degraded accuracy
and damage to the CTs. CTs should not be removed from conductors while under load. Once
installed on a conductor that has load present, the CT must be connected to the BGS16.
Failure to do so will create a safety hazard and result in damage to the CT.
Split core CTs include 24 AWG 600V twisted pair leads that terminate in the CT
Interconnect Board. The CT Interconnect Board is connected to the BGS16 using the
provided CT Interconnect Cable (shielded ribbon cable).

Packet PowerMulti-Circuit Monitor BGS16 User Manual V2.0

Communication
The BGS16 utilizes Packet Power’s advanced zero-configuration wireless mesh networking
technology which automatically connects the BGS16 to an Ethernet Gateway when
energized. Each Gateway can support up to fifty BGS16s; additional Gateways can be added
for capacity or redundancy.
The BGS16 must be able to establish a wireless connection either directly to a Gateway or to
another Packet Power wireless device.
Data can be accessed from the Gateway in one of two ways:
Third Party Device Data Acquisition - Third party monitoring systems can access data
from a Gateway via SNMP, Modbus TCP/IP, Ethernet/IP, MTConnect, BACnet/IP and
MQTT protocols.
Cloud Based Data Acquisition - Data can be simultaneously exported to the Packet Power
EMX monitoring portal (local or cloud based).

SECTION 4: OPERATIONS
Start Up
The BGS16 ships fully preconfigured. Once power is supplied, the system will automatically
connect to any Gateway that is within range and set to the same radio zone.
Each BGS16 contains two component meters. Each meter has LEDs that glow when powered
on. The cover of the BGS16 allows viewing the LEDs making it possible to verify that both
component meters are powered up and that the lights on both units are flashing in a
consistent manner.
Each BGS16 has a unique 16-digit ID number that can be found on a label located on the
outside of the unit in the top left corner. Each component meter also has a unique 16-digit ID
number on the meter’s front label. Once the meter makes a wireless connection to a Gateway,
the readings from that meter can be accessed via the Gateway’s console.
Packet Power provides documentation that is unique to each BGS16 and associates each CT
to its component meter. See Appendix for sample. This documentation is required in order to
access readings using protocols such as SNMP or Modbus. Customers using Packet Power’s
EMX application will be provided with panel maps to load into EMX.
At initial start-up, it is highly recommended to validate correct operations by placing a
known load on each circuit and verifying that the load is correctly reflected by the system,
first at the Gateway console to validate the physical connection, and then in the monitoring
application to validate the mapping logic.
Operation
Normal operation is characterized by the regular flow of monitoring data. This is typically
verified on a continual basis via the site’s monitoring application. Please consult the
monitoring application’s documentation for how to achieve this using your application.
To prevent damage to the BGS16, ensure power is
disconnected whenever abnormal or extreme
power conditions may exist such as during
infrastructure commissioning.
Instructions for accessing the Gateway console can be
found on the Packet Power web site:
https://dox.packetpower.com/Ethernet---Gateway---
Version---4---Web---Console.html

Packet PowerMulti-Circuit Monitor BGS16 User Manual V2.0

Shutdown
No special preparation is required prior to shutdown. Using a customer-provided disconnect
such as a 3-pole breaker, simply shut off power to the BGS16. Note that this disables power
to the monitoring unit only.
The conductors on which the CTs are installed will still have live load and
must be treated accordingly, and the panel itself will still have live voltage
and present a risk of electrocution.
Troubleshooting
If the BGS16 does not light up once power is supplied:
Ensure access to power. Check that the customer-supplied breaker protecting the
circuit providing power to the BGS16 is closed and that the supplied voltage source
leads have been connected to the proper phases (see “Voltage Connection” section of
this document).
Check the quick disconnect. A quick disconnect may be present on the voltage leads
near the supply side of the terminal block in the BGS16 unit. Separate it and
reconnect it, ensuring there is a clean connection.
Check the inline fuses. Remove the BGS16 cover and locate the terminal block that
connects to the voltage source wires. Follow the wire harness on the side of the
terminal block that feeds into the BGS16 to locate the inline fuse holders. Open each
fuse holder and inspect for blown fuses. Replace with 5x20mm glass 5A/250V fuses.
Replace the cover and reconnect power.
Verify voltage presence. If no power is flowing, use a multimeter to verify that
voltage is present for each phase at these locations and contact Packet Power support
with the results:
oWhere the BGS16’s voltage leads connect to the customer-supplied protective
breaker.
oOn the supply side of the voltage terminal block inside the BGS16.
oOn the meter side of the voltage terminal block inside the BGS16.
oOn each phase of the green terminal block connectors in the wire harness that
distribute power within the BGS16.
If a subset of the monitoring readings are missing:
Verify that all monitoring modules are active by looking at the BGS16 face to see that
both units are lit up and blinking in a similar pattern. If not, contact Packet Power
support.
If all units are lit up, check to see that all units are reporting via the wireless mesh to a
Gateway. Note that the LEDs on a meter that cannot join a mesh will flash using a
different pattern than those that are communicating. If this is occurring, note the
location of the missing meter (ideally, take a short video of the unit) and contact
Packet Power support.
