2 PRODUCT DIAGRAM A VOLTAGE LEADS Connect the leads to the three-phase source to be monitored. Input range is 08 to 480V. B MANDATORY FUSE PER NEC Maximum current draw is 60 ma. Fuses provided by factory are rated /A., 600V, 00kC. For continued protection, replace only with the same type and rating. C N BUS Connect to an N Trunk. Please refer to wiring diagram on next page. D STATUS LED The LED blinks green when the product is functioning normally. It will blink slowly, approximately one second on, then one second off. If the LED is red and blinking slowly, it may indicate incorrect wiring or a power factor that is less than 0.5. If the LED is red and blinking fast the CT's maximum current rating has been exceeded. E ADDRESS SELECTION SWITCHES Each device on the N BUS must have a unique address. These switches must be set to assign an individual address before the device is connected to the N BUS. CAUTION: If an address is selected which conflicts with another device on the N BUS, both devices will be unable to communicate. F EXTERNAL CTs These external CTs are permanently attached and must not be disconnected and used with other power meters.! Color match CTs and voltage leads! Example: Clamp the red label CT around the power conductor that the red voltage wire is connected to.

When monitoring devices controlled by variable frequency drives, always connect the meter(s) to the line side (NEVER the load side). CONNECTING H8000 SERIES METERS TO THE LOAD SIDE OF A VARIABLE FREQUENCY DRIVE WILL PERMANENTLY DAMAGE THE ELECTRONICS! Note: The meter cannot communicate on the N bus without power. Therefore, it is best to connect the voltage leads ahead of switching devices.

Only load. addresses to 63 may be used. This address will be required when adding the hardware object at Metasys. 5 Remove the terminal block and attach the N BUS. Positive (N+), negative (N-) and REF wires must be connected as shown in Figure Disconnect power and lock-out all power sources during installation. DO NOT CONNECT VOLTAGE INPUTS LIVE! Connect the voltage leads to the phase conductors, as shown in Figure. Since the meter requires voltage to communicate, connect the leads to a location which is not normally switched off. Connect the red lead to the conductor most convieniently located to physically mount the CT with the N BUS connector. After selecting the conductor for the red lead, the black and yellow leads may be attached to either of the other two conductors. Attach CTs to conductors. Each CT must be attached to the same conductor as the correspondingly colored voltage lead. (See wiring diagram above) The unit will automatically detect phase reversal, so it is not impor- 3/ If necessary, insulate any exposed N wiring. Ensure that the insulation complies with local and national electrical codes. When installing multiple meters, attach all N BUS connectors to the network trunk cable as shown in Figure 3, then connect the individual meters to the trunk. Set up Metasys (see page 6). Approximate Check of Power Reading:. Check actual current with Amp clamp. Expected power is: = x Amps x.73 x PF 000 = Horsepower x.746 This should be compared with value read by -.

6 H805 TYPICAL METASYS SETUP. Define a hardware object Type N Device, Device type: "VND". Add H Accumulator (Consumption) Point Directly map BI point to an accumulator (ACM) object at Metasys. Refer to the Range/Value column in the point map (page 4) for the "pulse constant" which corresponds to the CT size used. The correct pulse constant must be used to obtain accurate data. The "Rate Constant" should be "Hour". 3. Add (Instantaneous Demand) Point Directly map point to an Analog Object. Do not use alarm or warning limits (see below). Alternatively, the CS model file H805.DDL may be used. 4. Add H Point (optional) Directly map point to an analog object. Do not use alarm or warning limits. Alternatively, the CS model file H805.DDL may be used. This point provides direct H accumulation display. H806 TYPICAL METASYS SETUP. Define a hardware object Type N Device, Device type: "VND". Add H Accumulator (Consumption) Point Directly map BI point to an accumulator (ACM) object at Metasys. Refer to the Range/Value column in the point map (page 5) for the "pulse constant" which corresponds to the CT size used. The correct pulse constant must be used to obtain accurate data. The "Rate Constant" should be "Hour". 3. Compile the CS model file (H806.DDL) to add the CS models for the H806 to your Metasys database. Type "DDL H806". 4. Add CS Object using the model H806A This allows access to the first 6 points. 5. Add CS Object using the model H806B This allows access to the remaining points. SPECIAL METASYS SETUP OPTIONS Setting Alarm or Warning Limits The H805 and H806 do not support alarm and warning status reporting for points. If alarm and/or warning limits are required, first define a CS object. Then map an AD object to each CS object point value attribute. However, alarm and warning limits may be used with the accumulator point. Resetting the H Accumulator Point BO- provides a reset button that will cause the H accumulator to reset when commanded to. This point will automatically return to 0 immediately after the H accumulator is reset. BO- should be directly mapped to a BO object defined with the auto restore flag set to N. This will prevent an accidental H reset if the meter goes off-line and returns. BO- should not be defined with a CS Model, because the CS Model would automatically set the auto restore flag to Y. Using Multipliers to Scale Data Points High voltage installations where the meter is powered by a potential transformer will require the data to be multiplied by the ratio of the transformer used. Most of these applications use pre-installed 5 amp output current transformers, with the 5 amp line wrapped many times through the H805/H806 meter. Two multipliers exist, one for the voltage, and one for the effective current ratio. For example, a 300:5 amp CT is pre-installed and the 5 amp loop is wound 0 times onto the H806 meter; effective current ratio would be 3. If a 0: potential transformer is used, then voltage points would need to be multiplied by 0, current points would need to be multiplied by 3, and power points would need to be multiplied by 60. Power factor points do not use multipliers. The H accumulator may be multiplied by changing the pulse constant. To apply multipliers to points, use a GPL process to do the math and write the multiplied value to a pseudo-point. Displaying H Use totalization to display H values. When displayed normally, the accumulator will show instead of H. The value associated with the accumulator should agree with -, but it will respond slowly as Metasys counts H over a period of time to compute. Alternatively, - provides a direct view of the accumulated H. For large values, BI- will provide better precision than -. Presetting the H Accumulator In some cases it may be necessary to preset the H accumulator to a specific value. This can be accomplished by writing to ADI- and ADI-. Computing the values to write to these points is not simple. Divide the desired H value by the H/count constant that corresponds to the CT size of the meter (see the point map), and round off to the nearest whole number. This is the raw count. Divide the raw count by and round down to the nearest whole number. If the value was greater than 3767, subtract This is the value to write to ADI-. Take the raw count, divide by 65536, subtract out the integer portion, leaving only the part to the right of the decimal point, and then multiply by If the value was greater than 3767, subtract This is the value to write to ADI-. Both points should be written when there is no power (- reads zero) to prevent the values from changing unexpectedly as they are written. Using the Avg/Min/Max Points (H806) The Average Demand (-5), Minimum Demand (-6), and Maximum Demand (-7) points measure their respective data during a period of time. They begin after BO- is commanded to. A typical usage would be to read these points at a regular interval, such as every 5 minutes, and then command BO- immediately after reading them. BO- should be directly mapped to a BO object defined with the auto restore flag set to N. 6/9

7 ADDRESS SELECTION SWITCHES Each device on the N BUS must have a unique address. These switches must be set to assign a unique address before the device is connected to the N BUS. If an address is selected which conflicts with another device on the N BUS, both devices will be unable to communicate. When setting the N BUS address, choose an address number which is not in use. Only N addresses in the range of to 63 may be used. Set the switches for the selected address by following the diagram below. This address will be required when adding the meter to Metasys. DO NOT USE ZERO! FIGURE /9 7

9 TROUBLESHOOTING Problem: STATUS LED does not blink. Solution: Check fuses and voltage connections. STATUS LED should blink regardless of CTs, N BUS connections and DIP switch setting. Problem: Power meter interferes with another device on the N BUS. Solution: Set DIP switches to a different N address which is not in use. Problem: Readings seem highly inaccurate. Solution: Check that each CT is installed on the conductor with the corresponding color voltage input lead attached. In most cases, incorrect wiring will cause the STATUS LED to blink RED (slowly). However, a Power Factor lower than 0.5 could cause the LED to blink this way, even if the unit is installed properly. It does not matter which side of the CTs face towards the load. Check actual current with Amp clamp. Expected power is: = x Amps x.73 x PF 000 = Horsepower x.746 PF is usually 0.7 to 0.95 depending on the nature of the load. Compare this to the value read by - If current is below -% of full scale maximum for the CT, a smaller CT should be used for very low currents. An alternative is to wrap each wire through each CT multiple times Problem: Meter off-line when load is switched off. Solution: Voltage leads must be connected on the Line side of the conductor. The power meter cannot communicate on the N BUS without voltage. Problem: STATUS LED blinks red. Solution: If the LED blinks quickly, approx. 5 blinks in seconds, the CT used is too small. A larger CT current rating is required. If the LED blinks slowly, approx. blink in two seconds, the CTs are not installed on the correct conductors, or the loads Power Factor is less than 0.5. The meter can accurately measure these low PFs, but few loads operate normally at such a low power factor.
