E683 Series CT

(sold separately)

E50H2A, E50H5A

Compact Power and Energy Meters

With BACnet MS/TP Support

For Use Only With E683 Series Rope CTs

Product Overview

The E50H2A and E50H5A 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 E50H2A has one pulse contact input and a phase loss alarm output. The E50H5A has data logging capability and two pulse contact inputs. The LCD screen on the faceplate allows instant output viewing. These meters include built-in CT integrators and CT power supplies. The E50H2A and E50H5A work only with Veris E683 series rope style CTs.

The meter is housed in a plastic enclosure suitable for installation on T35 DIN rail according to EN50022. It can be mounted with any orientation over the entire ambient temperature range, either on a DIN rail or in a panel. The meters are not sensitive to CT orientation, reducing installation errors.

Installation Guide

Power Monitoring

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).

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

Snap onto

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 E50HxA power meters have a number of dierent possible system wiring congurations (see Wiring section). 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 display as “----” on the User Interface or as QNAN in the BACnet objects.

WARNING

RISK OF ELECTRIC SHOCK OR PERMANENT EQUIPMENT DAMAGE

CT terminals are referenced to the meter’s neutral and may be at elevated voltages:

· Do not contact meter terminals while the unit is connected

· Do not connect or short other circuits to the CT terminals

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

1. Turn o all power supplying this device and the equipment in which it is installed before working on the device or equipment.

2. Always use a proerly rated voltage sensing device to conrm that all power is o.

3. Connect the CT output leads to the meter inputs. The white wire is the X1 lead. The E683x CT has an arrow indicating the source side.

4. Release the clasp on one side of the CT and open it on the hinge.

5. Fit the Rogowski coil around the conductor, bringing the coil ends together.

6. Lock the coil by turning the ring clockwise as shown in the diagram at right.

7. Reconnect power to the panel.

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 ear th connection (G) is required for electromagnetic compatibility (EMC) and is not a protective earth ground.
