6.7.2 Connecting the cables
6.7.2.1 Checking the cable insulation
• Measure the insulation of each cable before connection and verify
that the results are within the specification of the cable
manufacturer.
• Leave the conductors unconnected at both ends until the
commissioning personnel has given permission to connect them.
⚠ CAUTION
Risk of flashover!
High voltages will be present in the terminal compartment. High voltages
can cause flashover between conductors with different electric potential,
and between a conductor and earth.
Therefore, route and connect the cables in such a way that the following
minimum clearances are maintained:
• 70 mm between cable lugs of conductors with a different potential
• 70 mm between the cable lug of a conductor and the parts with
earth potential
• 30 mm between cables with a different potential
