How to connect the power supply to the industrial switch us1

To connect the power supply to an industrial switch, ensure the power is off, connect positive and negative terminals correctly, and establish a proper ground before powering the device.

Safety First

Before starting, disconnect all power sources to prevent electrical shock or equipment damage. Remove jewelry and metal objects, and ensure the work area is dry and well-ventilated. Only qualified personnel, such as licensed electricians, should perform the installation ( ).

Required Tools and Materials

Apply gentle pressure to ensure proper seating ( ).

Connect DC or AC Power Wires

For D

C power: connect the positive wire from the power source to the positive terminal on the switch, and the negative wire to the negative terminal ( ).

For A

C power: connect live and neutral wires according to the switch specifications, ensuring proper fusing and compliance with local electrical codes ( ).

Establish Grounding

Connect the frame ground (FG) or ground terminal on the switch to a protective earth (PE) point. For dual-ground setups, use the supplied dual-hole lug and 6-gauge wire ( ). Always connect the ground first when installing and disconnect it last when removing the power supply ( ).

Check Connections

Ensure all wires are securely fastened and that no bare conductors are exposed. Verify that the power supply is fully seated and that the covers or faceplates are installed to prevent exposure to high voltage and EMI ( ).

Power On

Once all connections are verified, restore power to the circuit.

Additional Precautions

Maintain proper ventilation: 5 mm on sides, 40 mm above, 20 mm below, and 10–15 cm from heat sources ( ). Do not connect primary and secondary sides together. Avoid installing in high-moisture areas or near water ( ).

Use surge protection for connected devices to prevent damage from electrical spikes ( ). Following these steps ensures a safe and reliable connection of the power supply to your industrial switch (US1), protecting both personnel and equipment.
