6.6 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
details in the sections above and tighten with the correct torque.
● The clearances between non-insulated parts have been maintained:
≥ 5.5 mm to 690 V, ≥ 8 mm to 1000 V.
● 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.
● The pressure relief device is undamaged (depending on the type of terminal box,
this involves either cast-in slots or an overpressure diaphragm). Only repair
damage after prior consultation with the person responsible for the safety of the
equipment and use only original parts.
