Supported System Types
The Energy Meter Series has a number of different possible system wiring configurations (see Section 4,
Wiring). 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 will 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:
• 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.
Figure 4-8 - Direct Connect Control Power (Phase to Neutral)
• Provide overcurrent protection and disconnecting
devices appropriate for the wiring.
• The earth connection is required for electromagnetic
compatibility (EMC) and is not a protective earth

Solid-State Pulse Output
The Energy Meter has one normally open (NO)
KZ Form A output and one normally closed (NC) KY
solid-state output. One is dedicated to energy (Wh),
and the other to Alarm. The Energy Meter also provides an additional NO reactive energy (VARh) contact. See the Setup section for configuration
information.
“ConF” in the ALARM -> PULSE screen, and enable
Energy pulse output configuration error bit in the
Modbus Diagnostic Alert Bitmap (if equipped).

8.2.
Set Pulse Energy — Wh/P
In Watt Hour (and 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. When
moving up to a larger energy, the meter will jump to
the first value where it can find a valid solution.
8.3.
Figure 8-1 - Solid-State Pulse Output
The solid state pulse outputs are rated for 24VAC/
DC max.
Maximum load current is 100mA at 25°C. Derate
0.56mA per °C above 25°C.
* The over-current protective device must be rated
for the short circuit current at the connection point.
** All pulse outputs and communication circuits
are only intended to be connected to nonhazardous
voltage circuits (SELV or Class 2). Do not connect to
hazardous voltages.
8.1.
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 icon, show
Minimum Duration Time —
Milliseconds per Pulse (mS/P)
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 maximum Pulses Per Second (PPS) is shown in
yellow.
8.4.
MultiFlex I/O Board Pulse Limits - Standalone Version Only
The MultiFlex board can read pulses at a maximum of 5HZ or 5PPS. The Energy Meter is capable
of pulsing faster than the 5PPS maximum that the
MultiFlex board can read.
Pulses should be greater than 80mS in length at a
maximum rate of 5HZ: Do not exceed 5PPS.
For Example:
• Values of 100, 250, or 500 will be read by the MultiFlex board.
• Values of 50, 25, or 10 will not be read by the MultiFlex board.
