Preparing cables for cable entries with sealing
modules
• Prepare cables with an outer cable screen or
shield for EMC bonding with the metal enclo-
sure of the cabinet as illustrated in 6-6.
• Install the sealing modules according to the
instructions of the sealing module supplier
(Roxtec AB).
6.9.3 Connecting the cables
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 cable conductors unconnected at
both ends until the commissioning engineer
has given permission.

NOTICE
Risk of flashover!
High voltages will be present in the terminal
compartment. High voltages can cause flashover
between the electric potential of different
conductors, and the electric potential of a
conductor and earth.
Therefore, maintain a minimum clearance of 55 mm
between a conductor and the terminals of any
other conductor, and between a conductor and
earth.
