1. Ensure the stability of the workbench and proper grounding.
2. Check whether the required cables and connectors for installation are available and that cable lengths are less than 100 meters.
3. The product does not include installation components. Prepare the necessary components based on the selected installation method, such as screws, nuts, and tools, to ensure a secure setup.
4. Power supply: 48V to 57V DC.
5. Environment: operating temperature -40°C to 75°C; relative humidity 5% to 95%.

4.3 Installation

The 45mm standard DIN-Rail installation is very convenient for most industrial applications. The installation steps are as follows:

1. Check whether the installation accessories for DIN-rail mounting are available (this product includes the necessary accessories).
2. Check whether the DIN-rail is securely fixed and whether there is a suitable location for installing the product.
3. Insert the lower part of the product’s DIN-rail mounting clip (with spring support) onto the DIN-rail, then press the upper part into place. Apply slight pressure to ensure the equipment is balanced and securely attached.
   

Note: Aluminum alloy DIN-Rail hooks have been fixed to the rear panel of the Switch.

Power on Power on: First insert the power terminal of the power cable into the device’s power port, then plug in the power cord and turn on the power. After startup, the switch will automatically initialize. If all port indicators turn on briefly and then turn off, the system has successfully reset. The power LED should remain on. Power off operation: Unplug the power cord first, then remove the wiring from the terminal. Please follow this sequence to ensure safe operation.

The following describes how to install a Switch on the wall:

Schematic diagram of wall mounted installation of industrial machine

1. Remove the DIN-Rail mounting plate on the rear board of the Switch.
2. Install the wall mounting board on the Switch as shown below.
3. Four wall screws are required to mount the Switch on the wall, as shown in the figure above.
4. When fixing the screws to the wall, do not screw the screws into the wall completely. Leave a space of about 2 mm for sliding the wall panel between the wall and the screws.
5. After securing the screws to the wall, place the four screw heads through most of the keyhole, then place the Switch vertically and tighten the screws to increase stability.
