Installation and Maintenance of Solid State Controls (Publication SGI-1.1
available from your local Rockwell Automation sales office or online at
http://www.ab.com/manuals/gi) describes some important differences
between solid state equipment and hard-wired electromechanical devices.
Because of this difference, and also because of the wide variety of uses for
solid state equipment, all persons responsible for applying this equipment
must satisfy themselves that each intended application of this equipment is
acceptable.
In no event will Rockwell Automation, Inc. be responsible or liable for
indirect or consequential damages resulting from the use or application of
this equipment.

Safety
Safety Considerations
Before installing and using this product, please read and understand
the following precautions.
ATTENTION Only qualified personnel, following accepted safety
procedures, should install, wire and service the
Powermonitor 3000 and its associated components.
Before beginning any work, disconnect all sources of
power and verify that they are de-energized and
locked out. Failure to follow these instructions may
result in personal injury or death, property damage
or economic loss.
ATTENTION Never open a current transformer (CT) secondary
circuit with primary current applied. Wiring between
the CTs and the Powermonitor 3000 should include a
shorting terminal block in the CT secondary circuit.
Shorting the secondary with primary current present
allows other connections to be removed if needed.
An open CT secondary with primary current applied
produces a hazardous voltage, which can lead to
personal injury, death, property damage or economic
loss.
IMPORTANT The Powermonitor 3000 is not designed for nor
intended for use as a circuit protective device. Do
not use this equipment in place of a motor overload
relay or circuit protective relay.
Allen-Bradley HMIs

Publication 1404-UM001D-EN-E - October 2004
1-2 Safety
Other Precautions
IMPORTANT The relay output contacts and solid-state KYZ output
contacts on the Powermonitor 3000 may be used to
control other devices through setpoint control or
communications. The response of these outputs to a
communications failure is configurable by the user.
Be sure to evaluate the safety impact of the output
configuration on your plant or process.
ATTENTION Electrostatic discharge can damage integrated circuits
or semiconductors. Follow these guidelines when
you handle the module.
•Touch a grounded object to discharge static
potential.
•Wear an approved wrist strap-grounding device.
•Do not open the module or attempt to service
internal components.
•If available, use a static safe workstation.
•When not in use, keep the module in its static
shield bag.

Chapter 2
Product Description
The Bulletin 1404 Powermonitor 3000™is uniquely designed and
developed to meet the needs of both producers of and users of
electric power. A Powermonitor 3000 system consists of:
•Master Module which provides metering, data logging, native
RS-485 communications and other advanced features depending
on the model
•Optional Display Module for configuration, entering commands
and displaying data
•Optional communications port to serve data to other devices
using a choice of networks
•Optional external devices and applications that display and
utilize data for reporting, control and management of power and
energy usage
The Powermonitor 3000 is a microprocessor-based monitoring and
control device ideally suited for a variety of applications including:
•Load Profiling – Using the configurable trending utility to log
power parameters such as real power, apparent power and
demand, for analysis of power usage by loads over time
•Demand Management – Understanding when and why demand
charges occur lets you make informed decisions that reduce
your electrical power costs
•Cost Allocation – Knowing your actual energy costs promotes
manufacturing efficiencies
•Distribution System Monitoring – Using power parameters to
show power flow, system topology and distribution equipment
status
•Emergency Load Shedding – Monitoring power usage to
preserve system stability in the event of sudden utility outage
•Power System Control – Managing system voltage, harmonic
distortion and power factor
The Powermonitor 3000 is a sophisticated modern alternative to
traditional electromechanical metering devices. A single Powermonitor
3000 can replace many individual transducers and meters. The
Powermonitor 3000 is simple to install, configure and operate, and
provides you with accurate information in a compact economical
package.

2-2 Product Description
Master Module
The Master Module contains the main microprocessor-based
monitoring functions, including terminations for power system
connections, status inputs, control outputs, a native RS-485
communications port and a port for the Display Module.
Configuration
Although the Powermonitor 3000 ships from the factory with default
settings, you need to configure it for your particular requirements.
You may configure the Powermonitor 3000 using the optional Display
Module. Alternately, you may use an external device or application to
write configuration, operational parameters and commands to the
Master Module through its native or optional communications port.
Optional external applications that you may use for Powermonitor
3000 configuration include RSPower32TM and RSEnergyMetrixTM
software operating on a computer with a Microsoft WindowsTM
operating system. Contact your local Rockwell Automation sales office
or distributor, or visit http://www.software.rockwell.com/ for more
information on available software packages.
Communications
Every Powermonitor 3000 comes with a native RS-485
communications port that supports the Allen-Bradley DF1 half-duplex
slave and Modbus RTU slave protocols. The native port is suitable for
communicating to master devices including:
•A-B PLC®-5, SLC™500 and ControlLogix processors
•RSLinx™software with DDE/OPC server functionality
•Modbus RTU masters
•Other third-party devices
•Software that you develop
You may also specify Powermonitor 3000 units with optional
communications ports including:
•Serial RS-232 (DF1 half-duplex or Modbus RTU slave)
•Remote I/O
•DeviceNet™
•Ethernet®and EtherNet/IP™
•ControlNet™

Product Description 2-3
You may easily integrate a Powermonitor 3000 into a programmable
controller based control and monitoring system using your choice of
the native or optional communications methods listed above.
Display Module
The Bulletin 1404 Display Module is an optional user interface device.
The Display Module provides the most economical and simplest
method for setting up and configuring the Master Module for
operation.
The Display Module has a highly visible, two-line LED display and
four operator buttons with tactile feedback. Use the buttons and
display to navigate through a series of menus for configuration,
commands and data display.
The Display Module is shipped with a 3-meter (10-ft.) long, shielded
4-pair cable that provides power and serial communications between
the Master Module and the Display Module. The Display Module fits
into a standard ANSI 4-inch analog meter cutout for panel mounting.
Only one Display Module may connect to a Master Module, although
you may use one Display Module to configure and monitor any
number of Master Modules one at a time.
