Safety Considerations

ATTENTION

Only qualified personnel, following accepted safety procedures, should install, wire, and service the Powermonitor 3000 unit 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.

Never open a current transformer (CT) secondary circuit with primary current applied.

Wiring between the CTs and the Powermonitor 3000 unit 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 unit 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.

The relay output contacts and solid-state KYZ output contacts on the Powermonitor 3000 unit may be used to control other devices through setpoint control or communication. You can configure the response of these outputs to a communication failure.

Refer to the Powermonitor 3000 User Manual, publication 1404-UM001 for information on configuring the outputs.

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.

• Use a static safe workstation, if available.

• Keep the module in its static shield bag when not in use.

About the Power Monitor

The Bulletin 1404 Powermonitor 3000 unit is uniquely designed and developed to meet the needs of both producers and users of electric power. A power monitor system consists of:

• a master module that provides metering and native RS-485 communication.

• an optional display module for configuration, commands, and data display.

• an optional communication port to serve data to other devices by using a choice of networks.

• optional external devices and applications that display and use data for reporting, control, and management of power and energy usage.



The Powermonitor 3000 unit is a microprocessor-based monitoring and control device ideally suited for a variety of applications including these:

• 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 power monitor is a sophisticated modern alternative for traditional electro-mechanical metering devices. A single power monitor can replace many individual transducers and meters. The power monitor provides you with easy to understand, accurate information in a compact economical package.

Powermonitor 3000 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 communication port, and a port for the display module.

Configuration

Although the power monitor ships from the factory with default settings, you need to configure it for your particular requirements. You may configure the power monitor by 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 communication port.

Refer to the Powermonitor 3000 User Manual, publication 1404-UM001 , for additional detail.

Optional external applications that you may use for power monitor configuration include

Install the Powermonitor 3000 Unit

Only qualified personnel should install, wire, service, and maintain this equipment. Refer to and follow the safety guidelines and pay attention to all warnings and notices in these instructions.

ATTENTION



• Wear an approved wrist strap grounding device.


• Use a static safe work station, if available.


See Product Dimensions on page 14

for mounting hole dimensions.

Mount the master module with four No. 8-32 UNC or M4 screws with flat washers and lock washers.

Mounting Considerations

Mount the Powermonitor 3000 master module in a suitable protective enclosure. Select an enclosure that protects the master module from atmospheric contaminants, such as oil, water, moisture, dust corrosive vapors and other harmful airborne substances. The enclosure should also protect against personal contact with energized circuits.

The ambient temperature within the enclosure must remain within the limits listed in the

Specifications, page 56

.

Select an enclosure that provides adequate clearance for ventilation and wiring for the power monitor and other equipment to be installed within the enclosure.

See Product Dimensions on page 14

for dimensions and spacing guidelines for the power monitor.

When installed within a substation or switchgear lineup, we recommend that the power monitor be mounted within a low-voltage cubicle, isolated from medium- and high-voltage circuits.



Mount the master module so that the metal grounding clips on the bottom of the mounting feet make direct contact with the enclosure mounting panel. If the mounting panel is painted, scrape or sand the paint down to bare metal. Use star washers to assure good long-term electrical contact with the mounting panel. Be sure that the mounting panel is properly connected to a low-impedance earth ground.

Mount the enclosure in a position that allows full access to the master module. Install the master module with the ventilation slots in the bottom and top of the unit unobstructed to assure adequate free convection cooling of its internal electronic components.

IMPORTANT

Use caution not to block the ventilation slots of the master module. All wiring and other obstructions must be a minimum of 50 mm (2.0 in.) from the top and bottom of the unit.

• Refer to

Specifications for ambient temperature requirements.



System Accuracy Considerations

User-supplied potential transformers (PTs) and current transformers (CTs), as well as wiring from the CTs to the power monitor, may reduce the accuracy of your power monitor system.

The quality of the power monitor’s measurements can be no better than the quality of the signals presented to its input terminals. It is your responsibility to select transformers that are adequate for the desired metering accuracy.

ANSI/IEEE C57.13, Requirements for Instrument Transformers, defines three classes of transformer accuracy: class 1.2, class 0.6, and class 0.3. The application should dictate the transformer accuracy class used.

PTs and CTs may introduce errors in three areas: ratio errors, phase errors, and bandwidth errors.

Ratio Errors

The voltage ratio of a PT is the number of primary turns of wire divided by the number of secondary turns. Manufacturing tolerances may cause the ratio to be slightly different than the design specifies, causing an error affecting the voltage input to the power monitor.

Likewise, the current ratio of a CT is a function of the ratio of the number of turns of wire on the primary and secondary. Some error in this ratio is quite common in commercial grade PTs and CTs.

Other errors include magnetic core losses, winding impedance, and the burden, or load, on the transformer secondary. The combination of these errors is known as Ratio Error. You may compensate for Ratio Error, if known, by adjusting the Basic Configuration entries for

PT and CT primary or secondary voltages.

For a PT, the Ratio Error increases as the transformer’s load current increases, so its total load impedance should be as high as possible. Conversely, a CT’s Ratio Error increases as the voltage supported by the transformer secondary increases, so its total load impedance, including the impedance of the wire connecting the CTs to the metering device, should be as low as possible. This is why 4 mm

2

(12 AWG) or larger is usually recommended for wiring

CTs with a 5 A secondary rating.



Phase Error

Phase shift between the primary to secondary signals is another source of inaccuracy introduced by the user-supplied PTs and CTs. Phase shift is generally not of concern for simple voltage or current measurements. When these signals are combined, for instance when calculating line to line voltage or phase power, the effect of phase shift can become significant. The difference in phase error among different transformers causes measurement errors. If all the PTs and CTs introduced a 5° phase shift, there would be no error in the measured quantities. If, on the other hand, the PTs had a phase error of 1° and the CTs had a phase error of 6°, there would be a 5° phase error in the power calculation. This would show up as power factor and reactive power (VAR) errors. Phase errors cannot be corrected by adjusting the power monitor configuration since the errors change based on varying conditions of the power system.

A typical PT phase error varies from ±1°…±0.25°, depending on the PT’s accuracy class.

Applying higher than rated voltage increases the phase error and may saturate the transformer and cause even larger errors.

The phase error in a CT increases as its current decreases, and is lowest when the current is greater than 80% of the CT rating. Because significant phase error can occur when CT current is less than 20% of rated current, CTs sized for protection do not perform well when used for metering.

The phase error of both PTs and CTs are also affected by the power factor of the load on the secondary. For best accuracy, loads should be resistive, with PT loads as high as possible and

CT loads as low as possible.

Bandwidth Error

For fundamental 50 or 60 Hz measurements, bandwidth error has no affect on accuracy.

However, for waveforms with significant harmonic content, the PTs and CTs you supply may attenuate higher harmonics. Most instrument quality PTs have a flat frequency response out to 3 kHz, or the 50th harmonic on a 60 Hz system. Current transformers, especially older, existing units, tend to be less linear, with a flat response only out to 300 Hz, or the fifth (60

Hz) harmonic. Wide-band instrument CTs are available for improved frequency response.

Bandwidth error cannot be corrected by adjusting the power monitor configuration.

In addition, operation of either the PTs or CTs at extremely low frequencies may also cause saturation and resulting magnitude and phase errors.

For more detailed information on instrument transformer accuracy and power measurement, refer to Bulletin 1403 Powermonitor II Tutorial, publication 1403-1.0.2

.



Wiring and Connecting the Power Monitor

ATTENTION

Only qualified personnel, following accepted safety procedures, should install, wire, and service the power monitor 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.

Wiring of the power monitor includes the following steps:

• Connection of voltage and current signals from PTs and CTs

• Connection of control power

• Connection of status inputs and status/control outputs

• Communication wiring

Follow these guidelines to help assure reliable, trouble-free operation of your power monitor:

• Install and connect all wiring. Use wire tags to identify connections. Bundle wiring neatly and maintain a minimum of 50 mm (2.0 in.) clearance from the master module ventilation slots to avoid a buildup of heat within the unit.

• Furnish and install properly-selected fuses for voltage signals and control power.

• Use 600V wiring rated at 75 °C (167 °F) or higher. We strongly recommend the use of flame-retardant wire rated VW-1 by Underwriters Laboratories.

• Use a shorting terminal block (you provide) for CT wiring, to permit servicing connected equipment, such as the Powermonitor 3000 master module, without de-energizing the power system.

• Use ring lugs or locking spade lugs for voltage and current connections to provide additional wiring security and safety.

• Pay careful attention to correct phasing and polarity for proper operation.

• Connect the master module to a low-impedance earth ground by using its grounding terminal and a dedicated grounding wire at least as large as the largest current-carrying wire connected to the master module. Keep grounding wiring as short as possible. To obtain maximum EMI immunity, the master module mounting feet should make electrical contact with the mounting panel.

Refer to Mounting Considerations on page 12

for additional information.

• Connect all equipment ground terminals (master module, PT, and CT secondary) to a single point, low-impedance earth ground.

For information on wire sizes and types for grounding electrical equipment, refer to

Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1

, or the

National Electrical Code published by National Fire Protection Association (NFPA).



Wiring the Master Module

Observe all wire lug sizes and screw torques for terminal blocks wire sizes and screw torques.

Refer to Specifications on page 56

.

Voltage and Current Inputs

The following sections give information on the selection of PTs and CTs.

Voltage Input and PT Selection

The power monitor is designed to connect directly to a power system rated up to 600V line-to-line (347V line-to-neutral). Higher system voltages require the use of user-supplied

PTs. Typical secondary voltage on a PT is 120V AC. Select the PT primary voltage to match the nominal voltage of your power system.

Connect short circuit protection, that you supply, between the power system and the power monitor. If PTs are used, install short circuit protection on the high-voltage side of the PTs.

Current Inputs and Current Transformer (CT) Selection

The current input on the power monitor is designed for a 5 A nominal current signal.

User-supplied CTs are required to connect your power system to the input of the power monitor. Select the CT primary current to match the nominal current of your power system.

ATTENTION

Never open a current-transformer secondary circuit with primary current applied. Wiring between the CTs and the power monitor 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.



The shorting terminal block should be located adjacent to the Powermonitor 3000 master module so that it is readily accessible should service be needed. Use 2.5 mm

2

(14 AWG) wire for the short run between the power monitor and the shorting terminal block. Use wiring of 4 mm

2

(12 AWG) or larger between the shorting terminal block and the CT so that the additional load of the wiring does not overload the CT and reduce its accuracy.

IMPORTANT

You may install either two or three CTs for any of the Delta or Open Delta wiring or voltage modes.

Refer to the wiring diagrams on pages 28 ,

30 , and

33

for wiring of a two CT configuration.

Whether there are two or three CTs in a circuit does not affect the voltage wiring.

Refer to the Powermonitor 3000 Unit User Manual, publication 1404-UM001 .

Do not install fuses or other overcurrent protection in the secondary circuit of a CT.

Refer to System Accuracy Considerations on page 16 for guidelines on PT and CT selection.


for information on voltage isolation levels and wire termination recommendations.

The wiring diagrams depict wiring methods for a variety of power system configurations. You need to configure your power monitor to match the power system configuration for correct operation.

Refer to the Powermonitor 3000 Unit User Manual, publication 1404-UM001 , for detailed instructions on unit configuration.

for acceptable control-voltage ranges and wiring termination information.

We strongly recommend that you use a separate source of control power from the power system being monitored. For applications where power system information is critical, consider the use of a user-supplied uninterruptible power supply so that the power monitor continues to operate during power system events such as significant sags, swells, and transient disturbances.

You are required to connect your power-monitor control power through user-supplied disconnecting means and overcurrent protection. We recommend a 1 A slow-blow fuse.

Status Inputs

ATTENTION

Do not apply an external voltage to a Status Input. These inputs have an internal source and are intended for dry contact input only. Applying a voltage may damage the associated input or internal power supply.



All Status Inputs are common to an internal 24V DC source on the SCOM terminal. Status input terminals S1 and S2 are positive polarity and SCOM is negative polarity.

For optimal EMC performance, we recommend wiring the status inputs by using shielded cable, Belden 8771 or equivalent, with the cable shield grounded at both ends where possible.

Communication Wiring

Methods for connecting communication wiring vary from option to option. This section provides guidelines for installing dependable communication wiring for your power monitor system.

ATTENTION

You must supply and install special high-level isolation when the possibility of high ground potential differences exists. This may occur when communicating with a unit connected to a power ground mat. Failure to install such isolation may lead to personal injury or death, property damage, or economic loss.

IMPORTANT

You need to configure communication for each communication option.

Refer to the Powermonitor 3000 Unit User Manual, publication 1404-UM001 , for detailed communication configuration instructions.



Native RS-485 Communication Wiring

The RS-485 communication standard supports multi-drop communication among as many as

32 stations or nodes.

The RS-485 port is also used for master module firmware upgrades in the field.

RS-485 communication wiring should be installed in a daisy-chain configuration. We recommend that you use Belden 9841 two-conductor shielded cable or equivalent. The maximum cable length is 1219 m (4000 ft). Use of a star or bridging topology is not recommended and will result in signal distortion unless impedance is matched for each spur

(star topology) or network (bridge topology).

If required, install suitable terminating resistors at the ends of the daisy-chain cable. For

RS-485, install a 150

Ω, 1/4 W terminating resistor (refer to the wiring diagram). Note that some RS-485 conversion devices are equipped with internal terminating resistors. Contact the manufacturer of the converter for additional information.

At one end of each cable segment, connect the cable shield to the SHLD terminal of the master module RS-485 port or the converter. The SHLD connection provides a low-impedance ground for high-frequency noise while attenuating DC or line-frequency signals.

The RS-485 port in the master module presents a standard load impedance to the RS-485 network, allowing the standard 32 nodes on a network.

Configuration options for the native RS-485 port include the protocol, device address, and the data rate. Defaults are:

• auto-detect protocol.

• device address = the Device ID assigned at the factory in the range 1…254.

• communication rate = 9600 bps.

Use of RS-232 to RS-485 Converter

You need a user-supplied RS-232 to RS-485 converter for communication between the power monitor native RS-485 port and an external device such as a computer or programmable controller RS-232 port. Examples include:

• B&B Electronics, Inc. part number 485SD9TB (DB-9 connection).

• Allen-Bradley catalog number 1761-NET-AIC.

Optional RS-232 Communication

Powermonitor 3000 units with a catalog number ending in -232 are equipped with an RS-232 serial communication port in addition to the native RS-485 port. The RS-232 communication standard supports point-to-point communication among two stations or nodes. You must select either optional RS-232 communication or native RS-485 communication. The two ports do not operate at the same time.

The optional RS-232 communication port is a data communication equipment (DCE) type device. It requires a straight-through RS-232 cable to connect with personal computers, programmable controller serial ports, and other data terminal equipment (DTE) devices. It requires a crossover cable for connection to a modem or other DCE devices. No terminating resistor is required.

The maximum cable length is 15.24 m (50.0 ft). Refer to the following wiring diagrams for cable pinout information for constructing your own cable using DB-9 and/or DB-25 connectors.

Optional Remote I/O Communication

Powermonitor 3000 units with a catalog number ending in -RIO are equipped with a remote

I/O port in addition to the native RS-485 port. Allen-Bradley remote I/O is a robust, widely used industrial data network that uses twinaxial cable as its physical media. The power monitor emulates a logical quarter rack and supports both polled I/O and block transfer communication. The remote I/O port and the native RS-485 port may be used simultaneously, although overall data throughput may be reduced.

Remote I/O communication wiring should be installed in a daisy-chain configuration. We recommend that you use Belden 9463 twinaxial cable or equivalent. The maximum cable length is shown in the Remote I/O Communication Rates table and varies with the data rate.

Use of a star or bridging topology is not recommended and will result in signal distortion unless impendance is matched for each spur (star topology) or network (bridge topology).

Be sure that all devices on your remote I/O network are capable of operation at the desired communication rate. Certain legacy devices may not support a 230.4 Kbps communication rate.

TIP

Some remote I/O devices are equipped with internal terminating resistors.

At each end of each cable segment, connect the cable shields to the SHLD terminal of the remote I/O port connector. The SHLD connection provides a low-impedance ground for high-frequency noise while attenuating DC or line-frequency signals. We recommend that you follow the standard blue/shield/clear color scheme for remote I/O to differentiate it from

Data Highway Plus (clear/shield/blue) cables.



Configuration options for optional remote I/O communication include the logical rack address and module group (the power monitor is always one-quarter rack), and data rate.

Defaults are rack 1, group 0, 57.6 Kbps.

Optional DeviceNet Communication

Powermonitor 3000 units with a catalog number ending in -DNT are equipped with a

DeviceNet port in addition to the native RS-485 port. The DeviceNet network is an open-standard, multi-vendor, industrial device data network that uses a variety of physical media. The DeviceNet network also provides 24V DC power to devices connected to the network. The DeviceNet port and the native RS-485 port may be used simultaneously, although overall data throughput may be reduced.

For detailed DeviceNet system installation information, including cable lengths, the placement of terminating resistors, power supplies, and other media components, refer to the

DeviceNet Cable System Planning and Installation Manual, publication DNET-UM072 .


.

Install suitable terminating resistors at the ends of the DeviceNet cable.

TIP

Some DeviceNet devices are equipped with internal terminating resistors.

IMPORTANT

You must install and wire a suitable 24V DC power supply to the V+ and V- conductors in the DeviceNet cable. The power monitor consumes less than 100 mA from the DeviceNet

24V DC supply.

Configuration options for optional DeviceNet communication include the node address

(MAC ID) and data rate. Defaults are node 63 and 125 Kbps.

Cleaning Instructions

ATTENTION



• Wear an approved wrist strap grounding device.


• Use a static safe work station, if available.


• Disconnect and lock out all power sources and short all current transformer secondaries before servicing. Failure to comply with these precautions can lead to personal injury or death, property damage, or economic loss.

1. Turn off all electrical power supplied to the master module.

2. Clean the master module with a dry, anti-static, lint-free cloth. a. Remove all dust and any obstructions from the cooling air vents on the upper, lower, and ends of the module. b. Be sure that the nameplate is clean and in good condition.

3. Clean the display module with a dry, anti-static, lint-free cloth. a. Remove all dust and foreign materials from the exterior of the module. b. Be sure that the graphic front-panel overlay and back nameplate are clean and in good condition.



Field Service Considerations

If the power monitor requires servicing, contact your nearest Rockwell Automation sales office. To minimize your inconvenience, the initial installation should be performed in a manner that makes removal easy.

• A CT shorting block should be provided to allow the Powermonitor 3000 master-module current inputs to be disconnected without making the user-supplied

CTs an open circuit. The shorting block should be wired to prevent any effect on the external protective relays.

• All wiring should be routed to allow easy maintenance at connections to the power-monitor terminal strips and the power monitor itself.

ATTENTION

Never open a current transformer (CT) secondary circuit with primary current applied.

Wiring between the CTs and the power monitor 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.

Firmware Upgrades

Power monitor firmware upgrades are of two types. Service upgrades are those that occur from time-to-time to improve operation and resolve issues. Product upgrades are optional firmware enhancements that you may purchase to convert your 1404-M5 master module to an 1404-M6 or 1404-M8, or your 1404-M6 to an 1404-M8.

Service upgrades may be available at no charge. Contact your local Rockwell Automation representative for information or visit the Internet at http://www.ab.com/PEMS .

Product upgrades are available for purchase. Contact your Rockwell Automation representative for additional information.

Master module firmware upgrades (of either type) are performed by using the native RS-485 communication port. Firmware upgrades may be performed without removing the power monitor from its installation. An RS-485 to RS-232 converter is required to connect between the power monitor and your personal computer communication port. Cycling power to the power monitor may be required to complete the firmware upgrade.

Factory-installed Communication Cards

The RS-485 communication is integral to the master module and cannot be removed. Adding or changing a second communication card to a power monitor must be done at the factory and is not field upgradeable.
