    IQ 150S/250S 3: Mechanical Installation CAUTIONS! • Remove the antenna before opening the unit. • Only use the front cover support if you are able to open the front cover to the extent that you can fit the front cover support into its base. DO NOT rest the front cover support on the inside of the meter, even for a short time - by doing so, you may damage components on the board assem- bly.

  • Page 33: 4: Electrical Installation

    Do not HIPOT/Dielectric test any Outputs, Inputs or Communications terminals. Eaton recommends the use of Shorting Blocks and Fuses for voltage leads and power supply to prevent hazardous voltage conditions or damage to CTs, if the meter needs to be removed from service.

  • Page 34: Electrical Connections

    4.2: Electrical Connections All wiring for the IQ 150S/250S is done through the front of the unit (lifting the cover with the power to the unit OFF) so that the unit can be surface mounted. Connecting cables exit the unit via two openings in the base plate (see figures 3.6 and 4.1).

  • Page 35: Ground Connections

    4.4: Voltage Fuses Eaton recommends the use of fuses on each of the sense voltages and on the control power, even though the wiring diagrams in this chapter do not show them. • Use a 0.1 Amp fuse on each Voltage input.

    Protocol. C.2: DNP Implementation PHYSICAL LAYER The IQ 150S meter can use RS485 as the physical layer. This is accomplished by connecting a PC to the meter using the meter’s RS485 connection (see Chapter 5). RS485 RS485 provides multi-drop network communication capabilities. Multiple meters can be placed on the same bus, allowing for a Master device to communicate with any of the other devices.

  • Page 210: C.3: Data Link Layer

    DNP 3.0 allows for addresses from 0 - 65534 (0x0000 - 0xFFFE) for individual device identifica- tion, with the address 65535 (0xFFFF) defined as an all stations address. IQ 150S/250S meters' addresses are programmable from 0 - 247 (0x0000 - 0x00F7), and address 65535 (0xFFFF) is recognized as the all stations address.

    IQ 150S C: DNP Map C.4: Transport Layer The Transport Layer as implemented on IQ 150S meters is subject to the following considerations: Transport Header Multiple-frame messages are not allowed for IQ 150S meters. Each Transport Header should indicate it is both the first frame (FIR = 1) as well as the final frame (FIN = 1).

    Application Data contains information about the Object and Variation, as well as the Qualifier and Range.

  • Page 213 Change to Modbus RTU Protocol State (Point 1) IQ 150S meters can of change from DNP Protocol to Modbus RTU Protocol. This enables the user to update the Device Profile of the meter (this does not change the meter’s Protocol setting). A meter reset brings communication back to DNP.
  • Page 214 Change to MODBUS RTU Protocol Energy Reset (Point 0) As stated previously, IQ 150S meters accumulate power generated or consumed over time as Hour Readings, which measure positive VA Hours and positive and negative W Hours and VAR Hours. These readings may be reset using Point 0.
  • Page 215 Analog Inputs support the following functions: Read (Function 1) A READ request for Variation 0 is responded to with Variation 4. Analog Inputs are used to communicate the following data measured by IQ 150S meters: • Health Check • Phase-to-Neutral Voltage •...
  • Page 216 • PT Numerator, Multiplier, Denominator Health Check (Point 0) The Health Check point is used to indicate problems detected by the IQ 150S meter. A value of zero (0x0000) indicates the meter does not detect a problem. Non-zero values indicate a detected anomaly.
