Several instruments may be mounted on a 19" Rack panel if desired. Three units will fit side by side on a standard 5.25" high panel. Figure 2 indicates the dimensions of the panel hole cutout. Leave adequate space surrounding the instrument when determining mounting arrangements.
Page 29: Back Panel & Wiring
3.0 BACK PANEL & WIRING The rear view of the M66x is shown in figure 3A with the fiber option port shown, however, it is also possible to have a meter with a serial port or without this option port. See Appendix A1 for detailed wiring diagrams covering the CT/VT measurement inputs.
Page 30: Auxiliary Power
3.1 Auxiliary Power The M66x meters are powered by connections to L1(+) and L2(-). A Blue LED Power (PWR) indicator is provided on the rear panel to indicate that the unit is powered ON. It is located on the right of the rear panel. There is an option that allows the voltage across the Auxiliary Power input voltage across terminals L1(+) and L2(-) to be monitored.
Page 31: Vt Inputs - Va, Vb, Vc, Vn (See Appendix A1 And Section 1.3)
3.2 VT Inputs – VA, VB, VC, VN (See Appendix A1 and Section 1.3) The M66x meter voltage (VT) signal inputs are connected to terminals 3-6 (see Appendix A1 for specific wiring configurations). Voltage signals are measured using a 12M ohm resistor divider with a continuous voltage rating of 7kV. This ideal impedance provides a low burden load for the VT circuits supplying the signals.

Page 40: Optional Energy Pulse Outputs
3.6 Optional Energy Pulse Outputs There is an option for 4 KYZ pulse outputs with common ground. Pulse output meters are consumption monitoring devices. A pulse output power meter will indicate the number of kWhs used by the system load. Historically, rotating meters could report their power information remotely, using a pair of contact closures attached to a KYZ line.
Page 41 Figure 7 – Pulse Output Connections KYZ configuration in the 60 Series is achieved by navigating to the Settings / Input screen of the instrument’s webserver. When the 4 digital KYZ option is ordered, the positive and negative KWHr and KVarHr can be assigned to any of the four outputs in whatever order is desired.
Page 42 Energy per Pulse (EPP)  The EPP parameter has a range of 10 to 10 with units of KWhr / kVARhr.  The default value of EPP is 10 KWhr / kVARhr primary engineering units.  The time between rising edges defines the length of the energy pulse as shown below.

Page 91: Measurements
6.0 MEASUREMENTS Basic measurement quantities are calculated and updated every 100 ms. These quantities include RMS Amperes and RMS Volts, Watts, VARs, VAs, Power Factor, all harmonic-based measurements (such as fundamental-only quantities), Energy, and Frequency, and Phase Angle. Note: For all of the following measurements, it is important to keep in mind that the specific protocol used to access the data may affect the data that is available, or the format of that data.
Page 92: Voltage Channels
6.3 Voltage Channels All voltage inputs are measured relative to a common reference level (essentially panel ground). See Appendix 1 for input connection information. Common mode signals can be removed by signal processing algorithms, instead of the more traditional difference amplifier approach. This greatly simplifies the external analog circuitry, increases the accuracy, and allows measurement of the Neutral-to-Ground voltage at the panel.

together. This represents the dot product of the voltage and current vectors, or the true Watts. The per-element VAs are calculated from the product of the per-element Volts and Amps. The per-element VARs are calculated from fundamental VARs. In any connection type, the Total Watts and Total VARs is the arithmetic sum of the per-element Watts and VARs.

Page 97: Frequency
6.9 Frequency The M66X monitors the change in Phase Angle per unit time using the Phase Angle measurement for the fundamental generated by the FFT. The System Frequency is the frequency of the input used for synchronizing the sampling rate. 6.10 Demand Measurements The traditional thermal demand meter displays a value that represents the logarithmic response of a heating element in the instrument driven by the applied signal.
Page 98: Ampere And Fundamental Ampere Demand
6.10.1 Ampere and Fundamental Ampere Demand Present Ampere Demands are calculated via the instantaneous measurement data used to calculate the per-phase Amperes. Upon power-up, all Present Ampere Demands are reset to zero. Maximum Ampere Demands are initialized to the maximum values recalled from non-volatile memory. Upon Ampere Demand Reset, all per-phase Present and Maximum Ampere Demands are set to zero.

6.10.5 Demand Interval The M66X uses 900 seconds (15 minutes) as the default demand interval for current. The default for average volts and average power measurements is 60 seconds. Three separate, independent demand intervals may be set for current, voltage, and power. The range of demand intervals is 10 to 9999 seconds.
