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.

E50B1A, E50C2A, E50C3A

Compact Power and Energy Meter

Product Overview

The E50B1A and E50CxA DIN Rail Power Meter provides a solution for measuring energy data with a single device. Inputs include control power, CT, and 3-phase voltage. The E50CxA 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. These meters include built-in CT integrators and CT power supplies. The E50B1A and E50CxA work only with Veris U018 series rope style CTs.

The meter is housed in a plastic enclosure suitable for installation on T35 DIN rail according to EN50022. The E50 can be mounted with any orientation over the entire ambient temperature range, either on a DIN rail or in a panel. The meter is not sensitive to CT orientation to reduce installation errors.

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

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 meter has 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 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 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 Modbus registers.

WARNING

RISK OF ELECTRIC SHOCK OR PERMANENT EQUIPMENT DAMAGE

CT negative 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. Connect the CT output leads to the E5xxxA meter inputs according to the following diagrams. The white wire is the X1 lead.

2. Squeeze the ribbed sections of the CT connector and pull the rope out of the connector to open.

3. Wrap the rope style CT around the conductor to be monitored.

4. Snap the connector back together securely, ensuring there is no dust or debris in the closure area.
