Final checks
Before closing the terminal box/terminal base of the machine enclosure, check the following:
• Establish the electrical connections in the terminal box in accordance with the information
in this documentation.
• Maintain the air clearances between non-insulated parts as described in Chapter Minimum
• Avoid protruding wire ends.
• In order not to damage the cable insulation, freely arrange the connecting cables.
• Connect the machine corresponding to the specified direction of rotation.
• Keep the inside of the terminal box clean and free from trimmed-off ends of wire.
• Ensure that all seals and sealing surfaces are undamaged and clean.
• Correctly and professionally close unused openings in the terminal boxes. Observe the
information in this documentation.
• Observe the information on torques in this documentation.
