1 Packaged with device. Core conductor of 6C telephone line should be minimum 0.128mm²[26 AWG].
2 Accura 2300 displays only measurements of one Accura 2350 selected.
3 It is not for firewatching, but for reference only. A temp sensor is mounted on the side of Accura 2300.
4 Predicted demand is calculated by assuming that present power is equal to power of the time remaining in the demand interval.
5 Not displayed on LCD screen of Accura 2300. It is available only on ethernet communication.
6 Only for dedicated communication with all Accura 2350s connected by 6C telephone line.
7 Namely means a maximum of 30 Accura 2350s for 2 ports[RJ12-1, RJ12-2] of Accura 2300.
8 Maximum extension length of 6C telephone line from one port of Accura 2300 to the last Accura 2350 module connected.
9 Built-in ethernet switch enables connection between two Accura 2300s without using any external switch.

14 Accura 2300 provides maximum, minimum, and average statistical information on voltage, current, and power over the aggregation interval.
This allows accurate trend analysis of the quality of voltage, current, and power because it includes information of measurement parameters that fluctuate instantaneously in the interval.
15. If RS-485 option is selected, digital input/output channels are substituted with RS-485 channel. Refer to ordering information.
16. Split-core single-phase single-hole power measuring module, Accura 2350-1PSCSH-800A/630A/400A conforms to IEC62053-22 Class 0.2S.

1 If through-hole current exceeds 250A, Accura 2350-3P-CT5A-75 using external CT should be chosen.
2 Only for dedicated communication with Accura 2300[or 2350] connected by 6C telephone line.
3 No functional difference between type A and B of RJ12A and RJ12B.
4 Namely means a maximum of 30 Accura 2350s for 2 ports[RJ12-1, RJ12-2] of Accura 2300.
5 Packaged with device. Core conductor of 6C telephone line should be minimum 0.128mm2[26 AWG].

4 Packaged with device. Core conductor of 6C telephone line should be minimum 0.128mm²[26 AWG].
5 For three phase measurement, three split-core single phase single hole power measuring
modules are needed, one module for each phase[A, B, C]. However in three phase 3 wires, only
two modules are needed. Refer to page 82 for three phase through-hole connection. 6 Split-core single phase single hole power measuring module, Accura 2350-1PSCSH-
800A/630A/400A conforms to IEC62053-22 Class 0.2S.

1 If through-hole current exceeds 250A, Accura 2350-3P-CT5A-75 using external CT should be chosen.
2 CT secondary current input range.
