DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

• Follow safe electrical work practices. See NFPA 70E in the USA, or applicable local codes.

• This equipment must only be installed and serviced by qualiﬁed electrical personnel.

• Read, understand and follow the instructions before installing this product.

• Turn oﬀ all power supplying equipment before working on or inside the equipment.

• Any covers that may be displaced during the installation must be reinstalled before powering the unit.

• Use a properly rated voltage sensing device to conﬁrm power is oﬀ. DO NOT DEPEND ON THIS PRODUCT FOR VOLTAGE INDICATION

Failure to follow these instructions will result in death or serious injury.

A qualied person is one who has skills and knowledge related to the construction and operation of this electrical equipment and the installation, and has received safety training to recognize and avoid the hazards involved. NEC2009 Article 100

No responsibility is assumed by Veris Industries for any consequences arising out of the use of this material.

Control system design must consider the potential failure modes of control paths and, for

certain critical control functions, provide a means to acheive a safe state during and after a path failure. Examples of critical control functions are emergency stop and over-travel stop.

WARNING

LOSS OF CONTROL

∙ Assure that the system will reach a safe state during and after a control path failure. ∙ Separate or redundant control paths must be provided for critical control func tions. ∙ Test the eect of transmission delays or failures of communication links. ∙ Each implementation of equipment using communication links must be individually

and thoroughly tested for proper operation before placing it in service.

Failure to follow these instructions may cause injury, death or equipment damage.

For additional information about anticipated transmission delays or failures of the link, refer to

NEMA ICS 1.1 (latest edition). Safety Guidelins for the Application, Installation, and Maintenance of Solid-State Control or its equivalent in your specic country, language, and/or location.

The E51H2 and E51H5 DIN rail power meters provide a solution for measuring energy data with a single device. Inputs include control power, CT, and 3-phase voltage. Both models support BACnet MS/TP protocol. The E51H2 has one pulse contact input and a phase loss alarm output. The E51H5 has data logging capability and two pulse contact inputs. The LCD screen on the faceplate allows instant output viewing.

The E51 meters are 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 EN50022. The E51 can be mounted either on a DIN rail or in a panel. Observe correct CT orientation

when installing the device.

Installation

Disconnect power prior to installation.

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 ush 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

Insert clips from inside

DIN rail

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).

The E51Hx power meters have a number of dierent possible system wiring congurations (see Wiring Diagrams, page 5). To congure the meter, set the System Type via the User Interface or by writing the Present_Value of AV2 with the System Type value in the table below. 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 congured 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 BACnet objects.

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 sucient 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.
