1. Package Contents
Thank you for purchasing unmanaged industrial Ethernet switches. Please open the box of your unmanaged industrial Ethernet switch. Your package should include the following items:
- 1 x Industrial Ethernet Switch
- 1 x Quick Installation Guide
2. Installing the Switch
2.1. Installing the Switch on a DIN Rail
Follow these steps for DIN rail installation:
- Wear an ESD wrist strap. Ensure the wrist strap makes good skin contact and is reliably grounded.
- Position the switch so that the spring of the DIN rail mounting bracket compresses against the upper edge of the DIN rail.
- Rotate the switch down toward the DIN rail until the DIN rail mounting bracket clicks into place.
Diagram Description (Figure 2-1): Illustrates the process of attaching the switch to a DIN rail. An arrow shows the switch being tilted downwards, with a numbered sequence (1, 2) indicating the points of contact and movement to secure the switch onto the rail.
2.2. Connecting the Grounding Cable
⚠️ WARNING! Correctly connecting the grounding cable for the switch is crucial for lightning protection and EMI protection.
The power input end of the switch features a noise filter with a central ground directly connected to the chassis. You must securely connect this chassis ground to the earth to safely release faradism and leakage electricity, thereby minimizing EMI susceptibility of the switch. To connect the grounding cable:
- Remove the grounding screw from the switch.
- Use the grounding screw to attach the ring terminal of the grounding cable to the grounding screw hole. Fasten the screw securely.
- Connect the other end of the grounding cable to the grounding system.
Diagram Description (Figure 2-2): Shows the rear or side panel of the switch. It highlights the grounding screw hole (1), the ring terminal of the grounding cable (2), the grounding screw (3), the grounding cable itself (4) (typically green and yellow), and a grounding sign (5) indicating the connection point.
2.3. Connecting a DC Power Cord
⚠️ CAUTION: To avoid connection mistakes, identify the positive (+) and negative (-) marks above the DC power receptacle for the terminal block connection.
Installation Procedure:
- Ensure the switch power is off.
- Correctly connect the grounding cable (refer to Figure 2-2).
- Connect the DC power to the positive (+) and negative (-) terminals of the terminal block. Use a red cord for the positive (+) connection and a black cord for the negative (-) connection. Fasten the screws using a screwdriver. This is shown in Figure 2-3.
- Turn on the power and check the power indicator on the front panel of the device. If the power indicator is on, the power supply is working normally.
Remark: Din-rail industrial Ethernet switches support redundant dual DC power supply. You can connect one or two DC power supplies according to your requirement.
Diagram Description (Figure 2-3): Depicts the DC power input terminal block on the switch. It shows two sets of power inputs (PWR1, PWR2) with positive (+) and negative (-) terminals. The diagram illustrates connecting a red wire to the positive terminal and a black wire to the negative terminal for power input.
2.4. Verifying the Installation
After completing the installation, verify the following:
- There is sufficient space around the switch for heat dissipation.
- The DIN rail or mounting ears are securely installed.
- The grounding cable is connected correctly.
- The power source meets the switch's requirements.
- The power cords are connected correctly.
- If an interface cable for a port is routed outdoors, ensure a network port lightning protector is used for that port.
- If a power line is routed from outdoors, ensure a surge-protected power strip is used for the switch.
⚠️ WARNING: Always turn off the power source before connecting the power wire.
⚠️ WARNING: Always ground the power source to ensure a stable and clean power input.
Low-quality power supplies may generate excessive electrical noise, causing power fluctuations. To prevent this, ensure proper grounding of the power source.
