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.

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

installations, the lines may be floating (such as a delta). If any lines are
tied to an earth (such as a corner grounded delta), see the Line to Neutral
installation limits. In CE compliant installations, the lines must be neutral
(earth) referenced at less than 300VACL-N

Direct Connect Control Power DC Control PowerTransformers (CPT) Connection
DC Control Power from 125VDC to 300VDC (UL and CE max.) The Control Power Transformer may be wired L-N or L-L. Output to
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.

CONNECTING TO THE T-VER-E50B2
The T-VER-E50B2 has three outputs. These outputs can be connected to HOBO loggers as shown below.
Notes when connecting to non-HOBO® devices:
•The T-VER-E50B2 has solid-state outputs rated for 30VAC/DC nom.
•VARh and Wh are normally open; Ah is normally closed.
•Maximum load current is 100mA at 25°C. Derate 0.56mA per °C above 25°C (e.g. 86mA@50°C).
•The over-current protective device must be rated for the short circuit current at the connection point.
•Pulse outputs are only intended to be connected to non-hazardous voltage circuits (SELV or Class 2). Do not connect to hazardous voltages.

TROUBLESHOOTING
Problem Cause Solution
The display is blank after applying control
power to the meter.
The meter is not receiving adequate power. Verify that the meter control power is
receiving the required voltage.
Verify that the heart icon is blinking.
Check the fuse.
The data displayed is inaccurate. Incorrect setup values Verify the values entered for power meter
setup parameters (CT and PT ratings, system
type, etc.). See the Setup section.
Incorrect voltage inputs Check power meter voltage input terminals
to verify adequate voltage.
Power meter is wired improperly. Check all CTs and PTs to verify correct
connection to the same service, PT polarity,
and adequate powering. See the Wiring
Diagrams section for more information.
