SECTION 1: GENERAL
HAZARDS
CAUTION
Read all instructions carefully prior to installation.
Always ensure power has been disconnected prior to doing any work.
The BGS32 should be installed only by qualified technicians. Familiarity with and
understanding of all terms used in this manual is assumed.
BGS32 should be deployed in conjunction with proper branch circuit protectors.
The user is responsible for ensuring that all work is performed in accordance with
local electrical codes and regulations and using appropriate tools and materials.
BGS32 should only be connected to the type of power source indicated on the label.
The current transformer(s) used with the BGS32 must be appropriate to the amperage
of the circuit(s) on which they will be used.
Only current transformers approved by Packet Power should be connected to the
BGS32. Using unapproved current transformers could result in inaccurate readings
and damage to the BGS32 device.
Current transformers shall provide two means of isolation from hazardous voltages.
When selecting a current transformer, the voltage and measurement category of the
circuit to be measured must be considered to ensure that the current transformer is
adequately insulated and rated. For 480V circuits, insulation shall be at least 600V
rated. For 240V circuits, insulation shall be at least 300V rated.
Prior to installation, check to make sure the BGS32 has not been damaged.
Following installation in the final product, the connectors on the BGS32 must be
fully enclosed and insulated from the external product enclosure in compliance with
all relevant local electrical codes and regulations.
A safety connection to electrical ground / earth must be used.
Once installed on a conductor, current transformers must be connected to the BGS32.
Failure to do so creates an unsafe condition and will result in damage to the CT.
Follow basic safety precautions to reduce the risk of electrical shock and damage to
equipment.
Store in a clean, dry location. Clean with a dry cloth.
Intended for indoor use only, do not install in a wet location.
Failure to use the product in the specified manner may lead to injury or death and
damage to equipment.

SECTION 2: OVERVIEW
The BGS32 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.
Service Voltage Service Types
The BGS32 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 BGS32. The BGS32 cannot be used on 480V
equipment if access to N is not present nor on 600/347V circuits. The BGS32 is powered
from the voltage source it is monitoring.
Current Transformers
The BGS32 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 BGS32.
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 Boards. The CT Interconnect Boards are connected to the BGS32 using the
provided CT Interconnect Cables (shielded ribbon cable).

Communication
The BGS32 utilizes Packet Power’s advanced zero-configuration wireless mesh networking
technology which automatically connects the BGS32 to an Ethernet Gateway when
energized. Each Gateway can support up to 25 BGS32s; additional Gateways can be added
for capacity or redundancy.
The BGS32 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).

Components
The BGS32 consists of a NEMA 1 monitoring enclosure, two CT interconnect boards with
loose CT leads or wire harnesses for attaching CTs, and the CTs themselves.

SECTION 3: INSTALLATION
IMPORTANT
1. Installation should be conducted by a qualified professional according to local
electrical codes.
2. Protective equipment should be used when handling a current transducer (CT) on a
live conductor.
3. Do not make adjustments to the BGS32’s internal wiring.
4. If you believe the BGS32, CTs, interconnect boards or leads have been damaged, do
not attempt to repair or use them. All components are built to spec by Packet Power
and are not intended for alteration in the field.
Please review the complete list of safety instructions in the Hazards sections of this
document.
Installation Overview
The BGS32 does not need to be configured prior to use.
1. Mount the BGS32 to wall or device using mounting tabs provided.
2. Run the voltage lead(s) to the voltage source and connect them to L1, L2, L3, N and
earth.
3. Mount the CT Interconnect Boards near the circuits being monitored.
4. Attach the connector at the end of the CT Interconnect Cable to the applicable CT
Interconnect Board header.
5. Run CT leads from the CT Interconnect Board to the respective circuits.
6. Connect each CT to the appropriate conductor.
7. Connect CT tails to the CT leads.
Once power is supplied, the BGS32 will automatically begin to transmit data.
Thoroughly review the details for each step prior to installation. Contact Packet Power
support with questions.
