Product Overview The E51 DIN Rail Power Meter provides a solution for measuring energy data with a single device. Inputs include Control Power, CTs, and 3-phase voltage. The E51 supports multiple output options, including solid state relay contacts, Modbus (with or without data logging), and pulse. The LCD screen on the faceplate allows instant output viewing. The E51 meter is capable of bidirectional metering. Power is monitored in both directions (upstream and downstream from the meter). The meter is housed in a plastic enclosure suitable for installation on T35 DIN rail according to EN 50022. The E51 can be mounted either on a DIN rail or in a panel. Observe correct CT orientation when installing the device.

Reinstall any covers that are displaced during the installation before powering the unit. Mount the meter in an appropriate electrical enclosure near equipment to be monitored. Do not install on the load side of a Variable Frequency Drive (VFD), aka Variable Speed Drive (VSD) or Adjustable Frequency Drive (AFD). Observe correct CT orientation. The meter can be mounted in two ways: on standard 35 mm DIN rail or screw-mounted to the interior surface of the enclosure. A. DIN Rail Mounting 1. Attach the mounting clips to the underside of the housing by sliding them into the slots from the inside. The stopping pegs must face the housing, and the outside edge of the clip must be flush with the outside edge of the housing. 2. Snap the clips onto the DIN rail. See the diagram of the underside of the housing (below). Clip flush with outside edge Snap onto DIN rail Insert clips from inside 3. To reduce horizontal shifting across the DIN rail, use two Veris AV02 end stop clips. B. Screw Mounting 1. Attach the mounting clips to the underside of the housing by sliding them into the slots from the outside. The stopping pegs must face the housing, and the screw hole must be exposed on the outside of the housing. 2. Use three #8 screws (not supplied) to mount the meter to the inside of the enclosure. See the diagram of the underside of the housing (below). Screw holes exposed for mounting Insert clips from outsideZL0067-0E Page 7 of 34 ©2018 Veris Industries USA 800.354.8556 or +1.503.598.4564 / support@veris.com 0818 Alta Labs, Enercept, Enspector, Hawkeye, Trustat, Aerospond, Veris, and the Veris ‘V’ logo are trademarks or registered trademarks of Veris Industries, L.L.C. in the USA and/or other countries. Other companies’ trademarks are hereby acknowledged to belong to their respective owners. TM E51C2, E51C3 Installation Guide Supported System Types The meter has a number of different possible system wiring configurations (see Wiring Diagrams section). To configure the meter, set the System Type via the User Interface or Modbus register 130 (if so equipped). The System Type tells the meter which of its current and voltage inputs are valid, which are to be ignored, and if neutral is connected. Setting the correct System Type prevents unwanted energy accumulation on unused inputs, selects the formula to calculate the Theoretical Maximum System Power, and determines which phase loss algorithm is to be used. The phase loss algorithm is configured as a percent of the Line-to-Line System Voltage (except when in System Type 10) and also calculates the expected Line to Neutral voltages for system types that have Neutral (12 & 40). Values that are not valid in a particular System Type will display as “----” on the User Interface or as QNAN in the Modbus registers.

Output to meet meter input requirements DC Control Power from 125 VDC to 300 VDC (UL and CE max.) Fuse Recommendations Keep the fuses close to the power source (obey local and national code requirements). For selecting fuses and circuit breakers, use the following criteria: • Select current interrupt capacity based on the installation category and fault current capability. • Select over-current protection with a time delay. • Select a voltage rating sufficient for the input voltage applied. • Provide overcurrent protection and disconnecting means to protect the wiring. For AC installations, use Veris AH02, AH03, AH04, or equivalent. For DC installations, provide external circuit protection. Suggested: 0.5 A, time delay fuses. • The earth connection (G) is required for electromagnetic compatibility (EMC) and is not a protective earth ground.Next >
