1. The device conforms to UL standards for the tested AC power supply voltage.
2. When installing fuses on the power line, it is recommended to use UL listed Class RK5 fuses above 2 A/500 V.
3. Accura 2300S can be connected with up to 15 Accura 2350 3P/1P modules per port(RJ12-1, RJ12-2).
When connecting the device with special-purpose modules, refer to the individual manual for each module.
4. It is provided with the product. 4C telephone lines cannot be used.
The conducting wire of the 6C telephone line should be at least 0.128 mm2 (26 AWG).
It is recommended to keep a distance of over 5 mm from the power lines generating high levels of noise.
5. It indicates the maximum length of the 6C telephone line used to connect Accura 2300S to all Accura 2350 modules with
each port(RJ12-1 or RJ12-2) on Accura 2300S.
6. The Shield line should be connected to the Ground terminal on Accura 2300S.
7. At 115,200 bps, a master can communicate with up to 16 slave devices,
and the maximum distance between the master and the slave is 600 m.
8. The duty cycle of pulse features the pulse period and pulse On time.
9. It indicates the device¡¯s input voltage range, thus the primary voltage refers to the value obtained by
multiplying it by the PT ratio when using external PTs.
10. For Delta connections, do not exceed 480 V ungrounded or 240 V corner grounded.
11. It indicates the line-to-neutral voltage and line-to-line voltage values in 3P4W mode and 3P3W mode, respectively.
12. The data are not displayed on the LCD screen of Accura 2300S and are provided only via communication.
13. The residual voltage is the RMS value calculated by summing up three-phase voltage values.
14. The harmonic data provided via communication include harmonics up to the 40th order.
15. It measures temperature not for fire monitoring but for reference only.
