The following special messages may appear throughout this manual or on the equipment to warn of potential hazards or to call attention to information that clarifies or simplifies a procedure. This is the safety alert symbol.
It is used to alert you to potential personal conserv hazards. Obey all safety messages that follow this symbol to avoid possible injury or death. CAUTION used without the safety alert symbol, indicates a potentially hazardous situation which, if not avoided, can result in property damage.
No responsibility en assumed by Schneider Electric for any consequences arising out of the use of this material. This chapter contains the main operating instructions. The remaining chapters explain the installation and setup steps required before the power meter is ready for use, and maintenance and troubleshooting procedures for the power meter after installation. The EM series power meter is a universal power meter. Otherwise, it will read your 640 incorrectly.
Cpnzerv settings, such as communication parameters, cknzerv also be programmed 640 needed. Schneider Electric stands behind your EM power meters with complete user support and service. The EM series power meter is designed for use in industrial and commercial installations by trained and qualified professionals, not for domestic use. The K and M indicators are lit together to show Giga readings. Five smart keys make navigating the parameters very quick and intuitive for viewing data and configuring the power meter.
The voltage and current terminals and the RS communication port are located on the back of the power meter. Three rows of alphanumeric displays, four digits each, display three RMS parameters simultaneously or one energy parameter. The displayed readings update every second.
Five smart keys to scroll through the display pages. The parameter name is also displayed each time when you press a key. This helps the user to know which parameter is currently displayed. No LEDs are lit. Amber LEDs are lit. Green LEDs are lit to indicate that the load is acceptable and should not be increased further. When lit, indicates that the reading is in Kilo When lit, indicates that the reading is in Mega When Kilo and Mega are lit together, the reading is in Giga When lit, indicates that the reading is negative as per IEEE and industry standard practice.
When PF power factor is lead capacitive load: 600 current is reversed: W active power is negative. Energy readings have eight digits, including four additional fractional digits. The maximum number the power meter handles is 9, G for RMS and energy values.
The display pages expand as you go to the right, much like the directory or explorer tree displayed on any computer. The display shows where you are headed. This is the easiest way to enter into the setup menu. Press the key that takes you in the desired direction. From the RMS page, press 2. To return to RMS, press Use.
The display shows RMS. Use down through the display pages. Kilo and Mega light up together to show Giga. Going right through Conzegv requires code entry to program these power meter settings. This is convenient for viewing from a distance. The power meter shows the parameter name for one second followed by the rm for four seconds. Press continuously for three seconds and then release. The display flashes AUTO and starts auto-scroll within the page group.
The display flashes AUTO and starts auto-scroll down the entire column of pages. Press any key to revert to manual scrolling. Auto scrolling is not possible in the setup parameters. Default Display View Page You can select any page as a user-set default display page.
You can scroll to other display pages. The user-set page is displayed two minutes after the manual scrolling is stopped by the user. To lock the user-set default page: The power meter displays LOCK.
To unlock the user-set default page: The power meter displays ULOC. Entry into setup PROG is allowed only when the display page is unlocked.

Only supervisor can unlock through communication. The EM series power meter displays: Three voltage measurements line-to-line: Current and voltage unbalance. Measures from whichever phase is active. Measures the speed of the generator. PF per phase and fm.
A negated W phase reading indicates CT reversal. You can quickly estimate the load by viewing the display without operating any keys. The bar graph consists of 12 segments. It offers ISO quality, accuracy, and functional flexibility. Selective models of this series have Modbus RTU communications capability. The power meters are designed for retrofit applications such as replacement of analog meters. Each can be used as a standalone meter in electrical control panels, power distribution units PDUswitch boards, uninterrupted power supplies UPSgenerator sets, and motor control center MCC systems.
The following table gives the technical specifications of the power meters. IEC ; Damped Oscillatory: IEC 2; Impulse voltage: Safety Precautions This section contains important safety precautions that must be followed before attempting to install, service, or maintain electrical equipment.
Carefully read and follow the safety precautions outlined below. Such work should be performed only after reading this entire set of instructions.
Assume that all circuits are live until they have been completely de-energized, tested, and tagged. Pay particular attention to the design of the power system.
Consider all sources of power, including the possibility of back feeding.

Neglecting fundamental installation requirements may lead to personal injury as well as damage to electrical equipment or other property. High voltage testing may damage electronic components contained in the power meter. Otherwise, the readings will be incorrect. However, incorrect settings will introduce errors in readings of other running systems.
Failure to follow this instruction can result in injury or equipment damage. To view the set parameters.
To view or edit set parameters. Here are few tips. Program the following setup parameters for accurate readings: Set e, values to match your CT primary and secondary values.
