Disconnect power prior to installation.
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 flush 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
Snap onto

Supported System
Types
TM
The meter has a number of different possible system wiring configurations (see Wiring section). To configure 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 configured 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:
•
•
•
•
S elect current interrupt capacity based on the installation category and fault current capability.
Select over-current protection with a time delay.
Select a voltage rating sufficient 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.

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

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 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
ft·lb (0.5-0.6 N·m).
• Use 14-24 gauge (2.1-0.2 mm2) wire.
Data Logging
(E50C3 only)
0.37–0.44 ft•lb
(0.5–0.6 N•m)
The E50C3 includes a data logging feature that records 10 meter parameters, each in its own buffer.
Configuration
Use register 150 to set the data logging time subinterval. Writing to the storage buffer is triggered by the subinterval timer. The
default subinterval is 15 minutes (at a 15 minute interval setting, the buffers 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 buffer is full. When the buffer 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 buffer 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 buffers. Each buffer is user-configurable with the Modbus address of the
16-bit data output to be stored. 32-bit data, such as floating point data or 32-bit integer energy accumulators, require two buffers.
However, the lower 16 bits of an integer energy accumulator can be stored in a single buffer (optional).
When the E50C3 is first installed, the buffers contain QNAN data, with a value of 0x8000. This data is considered invalid. If the
buffer is reset at any point, all entries in the buffers are overwritten with this 0x8000 value, indicating that it is invalid. All invalid
data is overwritten as the meter fills the buffer with new data entries.
Reading Data
Use register 158 to choose which buffer 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 buffer to read. Data from the selected buffer
appears in registers 8000 to 13760.

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 buffer is being updated.
The Log Status Register has additional error flag 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 modified via Modbus commands).

Overview
TM
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 configuration registers 155-178 and buffer reading at registers 8000-13760. For
security reasons, configuration and resets on all E50 models are protected by a user configurable 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 floating point registers do not need to be
scaled.
Integer registers begin at 001 (0x001). Floats at 257 (0x101). Configuration registers at 129 (0x081). Values not supported in a
particular System Type configuration will report QNAN (0x8000 in Integer Registers, 0x7FC00000 in Floating Point Registers).

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)
82-32000
System Voltage: 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 configuration (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).
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).

Scale Factors
Note: These registers contain a signed
integer, which scales the corresponding
integer registers. Floating point registers
are not scaled. Scaling is recalculated
when the meter configuration is changed.
Phase Loss Voltage Threshold in percent of system voltage (register
134). Default is 10 (%). Any phase (as configured in register 130)
that drops below this threshold triggers a Phase Loss alert - i.e.
if the System voltage is set to 480 V L-L, the L-N voltage for each
phase should be 277 V. When the threshold is set to 10%, if any
phase drops more than 10% below 277 V, (less than 249 V), or
if any L-L voltage drops more than 10% below 480 V (less than Phase Loss Output
432 V) the corresponding phase loss alarm bit in register 146 will
be true.
Note: The phases tested are determined by
Phase Loss Imbalance Threshold in Percent. Default is 25% phase the System Type.
to phase difference. For a 3-phase Y (3 + N) system type (40 in
register 130), both Line to Neutral and Line to Line voltages are
tested. In a 3-phase Δ System type (31 in register 130), only Line
to Line voltages are examined. In a single split-phase (2 + N)
system type (12 in register 130), just the line to neutral voltage
are compared.

Logging Read Page Register. Selects which of the Register Logs to read (see registers 169-178). 1-10 are valid
entries that put the meter into log reading mode, temporarily pausing logging. When set to 0 (no variable
selected for reading), normal logging resumes. The meter will buffer one set of log entries while in reading
mode if a sub-interval timeout occurs (read/write collision). Default is 0.
Warning: this buffered data will be written to the log and logging will resume on the following sub-interval
timeout whether the page register has been cleared or not, resulting in the appearance of data moving in the
buffer during reads. To avoid this, log buffer reads should be completed and this register set back to 0 in less
time than the Demand Sub-interval (preferred) or logging should be halted by setting Bit 1 in register 158
(logs may be missed)

Logging Status Register (Bit Mapped):
Bit 0: Log buffer full – Set to 1 when one single shot mode has filled the log buffer. The Logged Entry Count will
continue to increment. Cleared to 0 when logging is restarted (see reset command register 129).
Bit 1: Log Buffer Read Collision 1 – Set to 1 if the meter tried to save log data while the user was reading the
log (Logging Page Register has been set to something other than 0). On the first collision, the meter holds the
data until the next sub-interval and then writes the saved data to the log as well as the data for that interval.
This bit is cleared to 0 on the first demand interval with Logging Page Register = 0.
Bit 2: Log Buffer Read Collision 2 – Set to 1 on the 2nd attempt to save log data while the user is reading the log
(Logging Page Register is set to something other than 0). At this point the meter ignores the read condition
and does a double write, first of the values saved from the previous cycle, and then the present values. If
the read condition is not removed the meter continues to write the log data as it normally would. This bit is
cleared to 0 on the first demand interval with Logging Page Register = 0.
Bit 3: Logging Reset – The Log has been reset during the previous demand sub-interval.
Bit 4: Logging Interrupted – Logging has been interrupted (power cycled, log configuration change, etc.) during
the previous demand sub-interval.
Bit 5: RTC Changed – The Real Time Clock has been changed during the previous demand sub-interval.
Bit 6: RTC Reset – The Real Time Clock has been reset to the year 2000 and needs to be re-initialized.

Log Buffer Wrap / Missed Log Counter. In continous mode, this counter increments each time the internal
circular log buffer wraps and overwrites old data. The total number of logged entries since the last log reset is:
(Register 161 x 5760) + Register 163. In single shot mode this counter is the number of log entries lost due to
the buffer being full. The counter is cleared on logging reset.
Max Number of Logging Days. Based on the Sub-Interval Length and the depth of the log buffer, this register
shows the maximum number of days that data will be logged following a reset until the Buffer is full (Single
Shot Mode) or overwrites old data (Continuous).
Number of Logged Entries since the log buffer wrapped or was reset. In single shot mode, this is the total
number of valid entries in the buffer. Any entries beyond this will read back as QNAN (0x8000).

Troubleshooting
Problem
Cause
The maintenance wrench icon
appears in the power meter display.
The display is blank after applying
control power to the meter.
The data displayed is inaccurate.
Solution
There is a problem with the
inputs to the power meter.
See the Alert sub-menu or the Diagnostic Alert Modbus Register
146
The meter is not receiving
adequate power.
Verify that the meter control power are receiving the required
voltage.
Verify that the heart icon is blinking.
Check the fuse.
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.
Power meter address is incorrect. Verify that the meter is correctly addressed (see Setup section).
Cannot communicate with power
meter from a remote personal
computer.
Power meter baud rate is
incorrect.
Verify that the baud rate of the meter matches that of all other
devices on its communications link (see Setup section).
Communications lines are
improperly connected.
Verify the power meter communications connections (see the
Communications section).
Verify the terminating resistors are properly installed on both ends
of a chain of units. Units in the middle of a chain should not have
a terminator.
Verify the shield ground is connected between all units.
