1. **Installation in Suitable Housing:** The terminal block must be installed in a housing suitable for the type of protection required for the specific area. Ensure the housing meets the requirements for flammable gases or combustible dust as per IEC/EN standards.
2. **Temperature Class:** The terminal block can be installed in equipment with temperature class T6, with the ambient temperature not exceeding +40°C. It can also be used in equipment with temperature classes T1 to T5, ensuring compliance with the highest permissible operating temperature.
3. **Installation on DIN Rail:** Snap the terminal blocks onto a DIN rail, ensuring proper alignment and spacing. Use partition plates or covers for isolation if needed. Secure the terminal block with end brackets to prevent twisting or movement.
4. **Use of Bridging Jumpers:** If using bridging jumpers, disconnect the contact tab of the plug-in bridge for the skip PE terminal to be disconnected. Note that using skip bridging from the ground terminals reduces the rated voltage នៃប្លុកស្ថានីយមូលដ្ឋានដែលបានតភ្ជាប់។
5. **Connecting Conductors:** Strip the conductors to the specified length, and if stranded, fit them with ferrules crimped using crimping pliers. Insert the conductor into the connection opening of the terminal block up to the stop. For small conductor cross-sections, open the terminal point before insertion using a bladed screwdriver.
6. **Technical Data:** Refer to the technical data provided in the សៀវភៅដៃ for details such as connection capacity, stripping length, and accessories required for installation.
7. **Certificate of Conformity:** Ensure that the product conforms with the relevant standards and directives, such as the ATEX directive, and consult the attestation of conformity for further details.
