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.

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.

Set Pulse:
The System Type , CT size, PT Ratio, and System Voltage must
all be configured before setting the Pulse Energy. If any of these
parameters are changed, the meter will hunt for a new Pulse
Duration, but will not change the Pulse Energy. If it cannot find a
solution, the meter will display the wrench, show “ConF” in the
ALARM -> PULSE screen, and enable Energy pulse output
configuration error bit in the Modbus Diagnostic Alert Bitmap (if
equipped).
Wh/P - Set Pulse Energy: In Watt Hours (& VAR Hours, if
present) per Pulse. When moving down to a smaller energy, the
meter will not allow the selection if it cannot find a pulse duration
that will allow the pulse output to keep up with Theoretical
Maximum System Power (see S_PWR screen). When moving
up to a larger energy, the meter will jump to the first value where
it can find a valid solution.
mS/P – Minimum Pulse Duration Time: This read only value
is set by the meter to the slowest duration (in mS per closure)
that will keep up with the Theoretical Maximum System Power.
The open time is greater than or equal to the closure time. The

Notes
• 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 k pull up to +5V, and RS-485- has a 47 k 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  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
ft·lb (0.5-0.6 N·m).
• Use 14-24 gauge (2.1-0.2 mm2) wire.

Data Logging
(EC only)
The E50C3 includes a data logging feature that records 10 meter parameters, each in its own buer.
Configuration
Use register 150 to set the data logging time subinterval. Writing to the storage buer is triggered by the subinterval timer. The
default subinterval is 15 minutes (at a 15 minute interval setting, the buers hold 60 days of data). An external timer can be used
over Modbus by setting this register to 0.
Use register 159 to turn on data logging and select either Single Shot or Continuous mode. (default is data logging on, Continuous
mode). In Single Shot mode, the meter records data until the buer is full. When the buer is full, the meter stops recording
new readings. Data for this time period is kept, but newer energy information is lost. In Continuous mode, the meter continues
to record energy data as long as the meter is operating. The buer can only hold 5760 entries at one time, however, so when the
number of records exceeds 5760, the oldest entry is deleted to make room for the newest.
Registers 169-178 contain the pointers to 10 data storage buers. Each buer is user-congurable with the Modbus address of the
16-bit data output to be stored. 32-bit data, such as oating point data or 32-bit integer energy accumulators, require two buers.
However, the lower 16 bits of an integer energy accumulator can be stored in a single buer (optional).
When the E50C3 is rst installed, the buers contain QNAN data, with a value of 0x8000. This data is considered invalid. If the
buer is reset at any point, all entries in the buers are overwritten with this 0x8000 value, indicating that it is invalid. All invalid
data is overwritten as the meter lls the buer with new data entries.
Reading Data
Use register 158 to choose which buer to read. When this register value is set to 0, the meter is in data logging mode. Changing
this value from 0 to (1 through 10) switches the meter to reading mode and selects a buer to read. Data from the selected buer
appears in registers 8000 to 13760.

Data Logging
(EC only,
cont.)
Read/Write Collision
If the demand sub-interval timeout occurs while the user is reading a page (register 158 ≠ 0), the log data will be held in RAM
until the next demand subinterval. At that time, both the saved data from the previous cycle and the new data will be written to
the log, whether the page register has been set back to 0 or not. Error bits in the Log Status Register (160) track these conditions.
Subsequent log writes will proceed normally. Provided the log read is concluded in less time than the demand sub-interval, this
mechanism handles the occasional collision and prevents the user from reading data as the buer is being updated.
The Log Status Register has additional error ag bits that indicate whether logging has been reset or interrupted (power cycle,
etc.) during the previous demand sub-interval, and whether the Real-Time Clock has been changed (re-initialized to default date/
time due to a power-cycle or modied via Modbus commands).

Overview
The E50C2 Full Data Set (FDS) features data outputs such as demand calculations, per phase VA and VAR, and VAh VARh
accumulators. The E50C3 data logging model adds conguration registers 155-178 and buer reading at registers 8000-13760. For
security reasons, conguration and resets on all E50 models are protected by a user congurable passcode. The meter supports
variable CTs and PTs, allowing a much wider range of operation from 90V x 5A up to 32000V x 32000A. To promote this, the meter
permits variable scaling of the 16-bit integer registers via the scale registers. The 32-bit oating point registers do not need to be
scaled.
Integer registers begin at 001 (0x001). Floats at 257 (0x101). Conguration registers at 129 (0x081). Values not supported in a
particular System Type conguration will report QNAN (0x8000 in Integer Registers, 0x7FC00000 in Floating Point Registers).

If register #7001 == 12345, then the 0x03 data would be“V12.345”).
Legend
The following table lists the addresses assigned to each data point. For oating point format variables, each data point appears
twice because two 16-bit addresses are required to hold a 32-bit oat value.
R/W R=read only; R/W=read from either int or oat formats, write only to integer format.
NV Value is stored in non-volatile memory.The value will still be available if the meter experiences a power loss and reset.
Format
UInt Unsigned 16-bit integer.
SInt Signed 16-bit integer.
ULong Unsigned 32-bit integer; Upper 16-bits (MSR) in lowest-numbered / rst listed register (001/002 = MSR/LSR).
Float 32-bit oating point; Upper 16-bits (MSR) in lowest-numbered / rst listed register (257/258 = MSR/LSR). Encoding
is per IEEE standard 754 single precision.
Units Lists the physical units that a register holds.
Scale Factor Some Integer values must be multiplied by a constant scale factor (typically a fraction), to be read correctly.This is done to allow
integer numbers to represent fractional numbers.
Range Denes the limit of the values that a register can contain.

congurable)
• • 133 R/W NV UInt 100 0.01-320.00 PT Ratio: The meter scales this value by 100 (i.e. entering 200 yields a potential transformer ratio of 2:1).The
default is 100 (1.00:1), which is with no PT attached. Set this value before setting the system voltage (below)
• • 134 R/W NV UInt 82-32000
SystemVoltage: This voltage is line to line, except for system type 10 which is line to neutral.The meter uses
this value to calculate the full scale power for the analog outputs and pulse conguration (below), and as full
scale for phase loss (register 142).The meter will refuse voltages that are outside the range of 82-660 volts
when divided by the PT Ratio (above).
• • 135 R NV UInt kW W 1-32767
Theoretical Maximum System Power:This read-only value is the theoretical max. power the meter can expect to
see on a service. This value is 100% of scale on the analog output (0-5VDC or 4-20mA), if equipped. The meter
recalculates this value if the user changes the CT size, system type, or system voltage.This integer value has
the same scale as other integer power registers (see register 140 for power scaling).
