1. The power source side and the load side are indicated as S and L, respectively.
Connections should be made properly according to the indicated polarity(+/ polarity(+/--). When the polarity is connected in
reverse, voltage and current are measured as negative values.
2. The DCM–50V module receives control power via DC busbar voltage in case of a stand–alone operation.
3. The number of DCM modules that can be connected to Accura 2300[S] is limited to 10(5 modules connected to each
of RJ12–1 and RJ12–2 ports).
4. Over/Under event s are detected by monitoring the voltage current data aggregat ed over 20 ms intervals.
5. In addition to the data obtained at 0.5–second aggregation intervals, the data aggregated over 1 second is also
provided. Refer to the aggregation section of Accura 2300[S] User Guide for details.
6. The rated voltages(Un) of the DCM 50V and the DCM 500V modules are 50 V and 500 V , respectively.
7. The minimum DC voltage for the stand alone operation of the DCM–50V module is 12 V , and a value below 12 V is not measured.
8. The measured value below the configured minimum measure d value is processed as zero.
9. The rated current(Ib) of the DCM–50V and the DCM–500V modules is 80 A .
10. Measured current values may involve errors as the tempe rature changes based on the calibra tion temperature.
11. An Over voltage/current event occurs when the measured value exceeds the threshold and is maintained during the delay time.
12. An Under voltage/current event occurs when the measured value exceeds t hreshold and is above or equal to the
th reshold 2 , and the value is maintained during the delay time.
13. The operations of different digital outputs are as follows.
14. A pulse features the pulse period and pulse on time.
15. Compliant with the UL61010–1 standard(3rd edition)
