1. When installing a fuse at the voltage input unit, it is recommended to use a fuse with ratings above 2 A/500 V
due to inrush current.
2. The maximum screw tightening torque of the barrier-type terminal block is 1.36 Nm (14 kgf-cm, 12 lbf-in).
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 internal conducting wire of the 6C
telephone line should be at least 0.128 mm
2
(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 G port.
7. Up to 16 modules can be connected to each bus at 115,200 bps.
8. The maximum screw tightening torque of the barrier-type block for digital input/output ports is 0.9 Nm (9 kgf-cm,
8 lbf-in).
9. The duty cycle of a pulse features the pulse period and the pulse on time.
10. 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.
11. It indicates the line-to-neutral voltage and line-to-line voltage in 3P4W mode and 3P3W mode, respectively.
12. Voltage THD(Total Harmonic Distortion):

13. The data are unavailable on the LCD screen of Accura 2300S and are only available via communication.
14. The residual voltage is the RMS voltage value calculated by summing up three-phase voltages.
15. It measures temperature not for fire monitoring but for reference only. (The temperature sensor is located at the
rear of Accura 2300S.)
