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.

RISK OF EQUIPMENT DAMAGE
Wiring Symbols
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.

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.

• The terminal’s voltage and current ratings are compliant with the requirements of the EIA RS-485 communications
standard.
• The RS-485 transceivers are ¼ unit load or less.
• RS-485+ has a 47 kΩ pull up to +5V, and RS-485- has a 47 kΩ pull down to Shield (RS-485 signal ground).
• Wire the RS-485 bus as a daisy chain from device to device, without any stubs. Use 120 Ω termination resistors at each
end of the bus (not included).
• Shield is not internally connected to Earth Ground.
• Connect Shield to Earth Ground somewhere on the RS-485 bus.
For all terminals:
• When tightening terminals, apply the correct torque: 0.37 to 0.44

Power Monitoring
The E50HxA is programmable via BACnet protocol and can easily be connected to a BACnet MS/TP network using an o-the shelf
BACnet router. It uses ve types of BACnet objects. A standard PICS (below) describes the required characteristics of the BACnet
implementation, but this additional descriptive context may be helpful to the integrator.
In addition to the required properties, the device object utilizes some optional properties to support other functionality, Time
Synchronization (primarily used for data/trend logging on the device) and Description and Location properties to simplify
installation and maintenance. Congure all of the meter’s functions, other than data logging and writable Device Properties, by
writing the Present_Value of the 11 Analog_Value objects. These values (except for the conguration register, AV1, which always
returns zero when read) are all readable and stored in nonvolatile memory so that they are retained if power to the device is
interrupted.
Data values other than log information and alerts are all accessed by reading the Present_Value of the 52 Analog_Input objects.
Most of these values are instantaneous readings of measured service parameters. Some of them, (AI1, AI26, AI27, AI37-AI45, AI47,
AI50 and AI51) represent accumulated values and are stored in nonvolatile memory as well. If power to the device is interrupted,
these values are retained, but no additional information accumulates until the device completes its re-initialization.
Alerts are used to indicate conditions of potential concern to the installer or the system, such as input voltage or current on any
phase that exceeds the meter’s measurement range, phase voltage below the Phase Loss Threshold set by the user, or Power
Factor below 0.5 on any phase. Alerts are accessible individually by reading the Present_Value of the Binary_Input objects or as a
group by reading the Present_Value of Analog_Input object 52. Alerts are not latched and do not generate events to system. They
indicate presence of these conditions at the time they are read, but the device does not latch and store them until they are read (if
the condition changes before they are read, the alert will go away).
All Analog_Value, Analog_Input, and Binary_Input objects implement the reliability property and use it to indicate that the
Present_Value properties are functional, valid and current. For complete assurance, check the Reliabilty property for a No_Fault_
Detected status before reading the Present_Value of any AV, AI or BI objects.
The E50H5A includes data logging capability, which is implemented using three Trend_Log objects. These are described in more
detail in the section on data logging.
