PowerMonitor 5000 Unit Overview

ATT EN TI ON : Only qualified personnel, following accepted safety procedures,

can install, wire, and service the PowerMonitor 5000 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 can result in personal injury or death, property damage, or economic loss.

ATT EN TI ON : Never open a current transformer (CT) secondary circuit with primary current applied. Wiring between the CTs and the PowerMonitor 5000 unit must 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.

Product Description

The PowerMonitor 5000 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 PowerMonitor 5000 unit is the next generation of high-end electric metering products from Rockwell Automation. This new family of meters provides advanced technology, new functionality, faster response, and superior accuracy. The M5 model is the base version and provides an extensive range of metering functionality. The M6 model expands the metering capabilities of the M5 with basic power quality monitoring functionality, including harmonics up to the 63rd, waveforms and logging, and classification of power quality events. The PowerMonitor 5000 unit communicates power and energy parameters to

controllers, HMI software, and applications such as FactoryTalk software over the Ethernet network or other optional networks. The PowerMonitor 5000 unit works with controllers or software applications to address key customer applications including the following:

• Load profiling – logging power parameters such as real power, apparent power and demand, for analysis of power usage by loads over time

(3) 2 PTs used in open-delta configuration.

Voltage Sensing

Circuits rated up to 690V AC line-to-line can be connected directly. Higher voltages require potential transformers (PTs), also known as voltage transformers (VTs), to step the voltage down.

Wiring must conform to all applicable codes and standards. In particular, suitable overcurrent protection must be provided by the user, with current and interrupting ratings selected to protect the wiring.

Pay particular attention to correct phasing and polarity of voltage connections. The diagrams use the ‘dot’ convention to indicate transformer polarity. The dot indicates the H1 and X1 terminals on the high side and low side of the transformer respectively.

When wiring a PowerMonitor 5000 unit to existing PTs and metering devices, the voltage sensing terminals of the PowerMonitor 5000 unit must be connected in parallel with the voltage sensing terminals of the existing metering devices.

IMPORTANT

To s horti ng te rmin al bl ock and current transformer (CT).

Current Sensing

Route the CT secondary wiring through the openings in the PowerMonitor 5000 unit as shown.

Use a shorting terminal block (included in the 1400-PM-ACC accessory kit), test block, or shorting switch (by user) for CT wiring to permit safely servicing connected equipment such as the PowerMonitor 5000 unit without deenergizing the power system.

Use 2.5 mm PowerMonitor 5000 unit and the shorting block. Use 2.5 mm

(14 AWG) or 3.3 mm2 (12 AWG) (maximum) wiring between the

(14 AWG) or larger wire between the shorting block and the CTs, depending on the length of the circuit. Longer circuits require larger wire so that the wiring burden does not exceed the CT burden rating and reduce system accuracy. Note that the diameter of the current sensing wiring openings is 7 mm (0.27 in.).

Ring lugs are recommended for making CT secondary connections. Standard ring lugs do not pass through the current sensing openings of the PowerMonitor 5000 unit. We recommend that the installer pass the wire from the shorting terminal block through the current sensing opening before crimping on ring lugs.

When wiring a PowerMonitor 5000 unit to existing CTs and metering devices, current sensing circuits of the PowerMonitor 5000 unit must be wired in series with the CT secondary and current sensing circuits of the existing metering devices.

Do not install overcurrent protection or non-shorting disconnecting means in CT secondary wiring. Connect the current sensing circuit to a low-impedance earth ground at only one point.
