Installation Example

The following figure shows an example of installing devices for temperature measurement in the

distribution panel. Accura 2300[S] and Accura 2350-TEMP devices are installed at the front of the

distribution panel, and multiple Accura TSEN devices are installed inside the distribution panel. The

Accura 2350-TEMP module has 1 DI(Digital Input) and 1 DO(Digital Output) channel, allowing for the

installation of the event reset switch and warning light.

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.

① Position the Accura 2350-TEMP module into the panel cutout.

② Fit the mounting wheel into the screw thread at the back of Accura 2350-TEMP.

③ Turn 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

① Fit the screw holes of the device’s mounting wings into the mounting holes of the panel.

② Fix Accura TSEN to the panel using the screws.

Fig 1.12

Mounting Accura TSEN on the Panel

DIN Rail Mounting

① Fit the bottom portion of the Accura TSEN device into the DIN rail on one side.

② Once 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.

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」.

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」.
