The Eaton PDI JCOMM®provides an enclosure for one or two Eaton Branch Circuit Monitoring Systems
(BCMSs) and can e attached to monitored power distri ution equipment or mounted on a near y wall.
JCOMMs can retrofit BCMSs to operational power distri ution units (PDUs) or Remote Power Panels (RPPs),
oth for Eaton and non-Eaton equipment.
Each JCOMM (Figure 1) can monitor these configurations:
• Two separate 208/120VAC/60Hz 3-phase 4-wire voltage sources to panel oards
• Up to four 42-circuit panel oards or 168 ranch circuits in total
• Up to four main feeds to panel oards or four su distri ution feeds to remote power distri ution equipment
Figure 1. JCOMM with Wa eStar Color Monitor
Local Power Monitoring Station. A JCOMM can have an optional WaveStar®Color Monitor, a 7-inch color
touchscreen display, capa le of displaying information for up to 20 downstream BCMS devices, such as
panel oards.
Alternatively, JCOMMs can e connected to a WaveStar BCMS Hu , which can typically monitor up to 70
BCMS devices.
JCOMM BCMS uses the same BCMS software that Eaton installs in factory- uilt power distri ution equipment
and can e networked with all other Eaton BCMSs.
NOTE The term PDI in this manual refers to products previous manufactured y Power
Distri ution, Inc. All service and support for these features are now supplied y Eaton.

JCOMM has a single enclosure type for all mounting situations (Figure 2).
The entire front of the enclosure swings open and the inside frame slides out for easy servicing of the BCMS
oards, optional monitor, and ca ling. Opening the JCOMM front gives access to the Connections Panel (on
left) and the Power Panel (on right).
Knockouts and pre-drilled mounting holes facilitate mounting on walls or on top of PDUs or RPPs.
• Power must e turned off and locked out efore removing the internal frame.
• Removing the internal frame should only e done y a licensed electrician or service technician.

The front panel mounts an optional WaveStar Color Monitor, a 7-inch color touchscreen.
The WaveStar Color Monitor can display information from the points lists for 20 downstream BCMS devices,
such as panel oards. The monitor is part of the Mod us network and has its own points list.
The Monitor can connect to upstream networks using Mod us RTU, Mod us TCP/IP, or SNMP.
22..55 BBCCMMSS DDaattaa AAccqquuiissiittiioonn BBooaarrddss
The frame can mount two BCMS Data Acquisition Boards, which are identical to PCBs used in factory-installed
BCMS and use the same software. Each BCMS is an independent monitoring system.
Each BCMS oard contains points lists (Mod us register maps) for two panel oards and their associated main
feeds. There are two points list options:
• The Normal list is specialized for alarm customization for ranch circuits.
• The Power-KWH points list is specialized for power monitoring for ranch circuits.
• The IEC points list is specialized for IEC panel oards.
BCMS software specific to the selected points list is loaded onto the oard at the factory.
If su distri ution feeds are monitored, the BCMS also uses a small third points list for two su distri ution
feeds.

JCOMM has connection panels so that customers do not have to make direct connections to the BCMS PCBs (
Figure 3).
Power Panel (right side). The Power Panel has connections for voltage measurement, power, and grounding:
• Two (2) sets of terminal locks for two voltage sources (208/120VAC/60Hz 3-phase 4-wire), allowing
separate voltages to each panel oard
• One (1) set of grounding terminals
• One (1) 24VDC power supply, fed from voltage source 1
• Two (2) power terminal locks, providing 24VDC to the BCMS data acquisition oards and optional monitor

The following is a list of actions to review when planning a JCOMM installation.
JCOMM enclosure installation
1. Select power distri ution equipment to e monitored y JCOMM BCMSs.
2. Based on (1), determine the num er of JCOMMs required (specified on order).
3. Select the location of each JCOMM and determine mounting method, conduit, and mounting hardware.
The customer provides all conduit and mounting hardware. (See paragraph
4.2 Install the JCOMM Enclosure)
a. Typically a JCOMM will e attached directly to a PDU or RPP or to a near y wall.
. Plan conduit and CT ca le harness lengths from JCOMM to circuits. If running ca les from under a
monitored unit, make provision for ca le ends to create correct ranch circuit addressing. (See
paragraph 4.5 Install Panelboard Branch Circuit CTs)
4. For power/voltage connections, the customer must provide
a. An approved electrical disconnecting means on each voltage source within sight of the JCOMM in
accordance with local codes and NEC standards. (See paragraph
4.3 Connect Ground and Voltage Sources)
. A ground connection in accordance with FIPS Pu 64, NEC standards, and local codes.
Monitors: local power monitoring stations
5. Determine monitors to e used as local power monitoring stations:
a. Determine which JCOMMs will have a display.
. Determine which BCMS devices will e monitored downstream of the display (panel oards and
su distri ution feeds).
c. Alternatively, determine if JCOMM BCMSs will e connected to a WaveStar BCMS Hu .
Communications
6. Determine protocols to e used etween the JCOMM monitors and the uilding management system
(BMS). (See paragraph 5.2 Upstream Protocols Using a Monitor)
7. Plan communications ca les (type and length) and BCMS upstream links to the BMS. Customers must
provide all communications ca les for connections upstream or downstream of a JCOMM. (See paragraph
5.1 Modbus etwork Setup)
8. Create a Mod us address map. Incorrect network addressing is a common BCMS startup pro lem. If
using a JCOMM monitor or WaveStar BCMS Hu with a Mod us upstream protocol, plan for downstream
Mod us addresses to e remapped upstream from monitors. (See paragraph
5.5 Remapping Modbus Addresses with Monitors)
Monitoring options
9. Select a points list. Points lists must e specified at time of order for loading into the BCMS oards. (See
paragraph 7.2 Panelboard Points Lists)
10. Plan setup options, especially warning and alarm parameters. (Review all of )

10 Eaton PDI JCOMM Enclosure Installation and Operation Manual P-164001107—Rev 01
Building Management System
11. Create a Mod us address map for network addresses as seen from the BMS, including remapped
upstream Mod us addresses when a JCOMM monitor or WaveStar BCMS Hu is used as a local power
monitoring station. (See paragraph 5.5 Remapping Modbus Addresses with Monitors)
12. Plan for efficient polling of warnings and alarms. (See paragraph 7.3 Alarm Handling)
