Pay attention to protruding wire ends so that the necessary air insulation<br />
clearances are observed.<br />
Measures to be taken before closing the terminal boxes<br />
Before closing the terminal boxes, please check that:<br />
•= the cables circuit connections are connected in accordance with the terminal<br />
diagram inside the terminal box cover.<br />
•= the electrical connections in the terminal box are tight and are in full compliance<br />
with the specifications given in the previous sections.<br />
•= the inside of the terminal box is clean and free of any cable pieces.<br />
•= all of the terminal screws and the corresponding cable entry parts have been<br />
firmly tightened (this also applies to any terminals that are not being used).<br />
•= the clearances in air are observed<br />
Table 3-6 General clearances in air<br />
Voltage Clearance in air<br />
up to 600 V > 8 mm<br />
up to 800 V > 10 mm<br />
up to 1200 V > 14 mm<br />
•= the connecting cables are laid in an open arrangement, and the cable insulation<br />
cannot be damaged.<br />
•= any cable entries which are not used are sealed and the plugs are inserted, i.e.<br />
in such a way that they can only be removed using the suitable tools.<br />
•= all of the seals/gaskets and sealing surfaces of the terminal box are in a good<br />
condition. If the leakproofness of the joins is achieved solely through metallic<br />
sealing surfaces, these must be cleaned and lightly regreased.<br />
