Step 1: Accura 2350-TEMP Installation
Panel Mounting
It is very easy to install the Accura 2350-TEMP module at the front of the distribution panel.
①Position the Accura 2350-TEMP module into the panel cutout.
②Fit the mounting wheel into the screw thread at the back of Accura 2350-TEMP.
③Turn the mounting wheel to the right and fix Accura 2350-TEMP to the panel.
You can easily turn the wheel with your hands. If you use excessive force when turning the wheel, it can
cause damage to the LCD screen of the Accura 2350-TEMP module.

Step 2: Accura TSEN Installation
The Accura TSEN device can be installed by using either the panel mounting or DIN Rail mounting
method.
Panel Mounting
①Fit the screw holes of the device’s mounting wings into the mounting holes of the panel.
②Fix Accura TSEN to the panel using the screws.
Fig 1.12 Mounting Accura TSEN on the Panel
DIN Rail Mounting
①Fit the bottom portion of the Accura TSEN device into the DIN rail on one side.
②Once one side of the device is latched on the rail, push the other side towards the panel so
that Accura TSEN can get snapped onto both ends of the DIN rail flanges.

Chapter 2 Accura TSEN Operation/Setup
Accura TSEN measures temperature with its built-in temperature sensor. It connects with the Accura
2350-TEMP module with a communication cable and sends data on the measured temperature to the
Accura 2350-TEMP module.
Up to 6 Accura TSEN devices can be connected to the Accura 2350-TEMP module using the daisy-chain
method. Accura TSEN devices can be installed at multiple locations in the distribution panel requiring
temperature measurement, allowing for the overall temperature monitoring in the distribution panel. For
details about how to connect Accura TSEN devices using the daisy-chain method, refer to 「Chapter 1
Installation & Wiring > Step 2: Accura TSEN Installation」.

Chapter 3 Accura 2350-TEMP Operation/Setup
Installed at the front of the distribution panel, the Accura 2350-TEMP module is connected with Accura
2300[S] using a communication cable. It receives power from Accura 2300[S] via the cable. The Accura
2350-TEMP module measures the external temperature of the distribution panel with its built-in
temperature sensor located at the front bottom of the device. By connecting with up to 6 Accura TSEN
devices using the daisy-chain method, the Accura 2350-TEMP module collects data on internal
temperatures at multiple locations of the distribution panel. It allows for the overall temperature control
of the distribution panel.
Users can check data on measured temperatures and set up events related to the temperatures on the
Accura 2350-TEMP module. Event alarms occur according to the settings, and users can check detailed
event data. Users can reset settings for external temperature events only on the Accura 2350-TEMP
module. However, for the events detected by the Accura TSEN device, users can reset event alarms only
with the RESET button on the Accura TSEN device.
For details about how to install Accura 2350-TEMP and connect it with Accura 2300[S] and Accura TSEN
devices, refer to 「Chapter 1 Installation and Wiring > Step 1: Accura 2350-TEMP Installation」.
