OPERATION

The E50B2 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 LCD screen on the faceplate allows instant output viewing.

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.

POWER MONITORING INSTALLATION GUIDE

INSTALLATION

Disconnect power prior to installation.

Any covers that may be displaced during the installation must be reinstalled 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).

The meter can be mounted in two ways: on standard 35 mm DIN rail or screw-mounted to the back of the enclosure.

A. DIN Rail Mounting

1. Attach 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 diagram of the underside

of the meter.

3. To prevent horizontal shifting across the DIN rail, use two 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

back of the enclosure. See diagram of the underside of the meter.

SUPPORTED SYSTEM TYPES

The E50B2 meter has a number of different possible system wiring configurations (see Wiring Diagrams, page 5–6). To configure the meter, set the System Type via the User Interface. 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 1L + 1n) and also calculates the expected Line to Neutral voltages for system types that have Neutral (System Types 2L + 1N and 3L + 1n).

Values that are not valid in a particular System Type will display as “----” on the User Interface

meet meter input requirements.

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:

• Current interrupt capacity should be selected based on the installation category and fault current capability.

• Over-current protection should be selected with a time delay.

• The voltage rating should be sufficient for the input voltage applied.

• Provide overcurrent protection and disconnecting means to protect the wiring. For DC installations, the installer must provide external circuit

protection (suggested: 0.5 A time delay fuses).

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