DANGER
Risk of electric shock
The insulating film in the terminal box protects against voltage flashover to the cover and
must not be removed.
CAUTION
Electrostatically-sensitive devices
The DRIVE-CLiQ interface contains electrostatically-sensitive components. Touching
connections with electrostatically charged hands or tools can cause malfunctions.
Note the ESD protection measures.
6.2.2 Cable entry and routing
● When selecting the required connecting cables, make sure that you take into account the
rated current and plant-specific conditions, such as ambient temperature, routing type,
etc. according to IEC / EN 60364-5-52 and IEC / EN 60204-1.
● Use EMC cable glands for permanently installed cable entries.
● Use shielded cables whose shields are conductively connected to a large area of the
terminal box of the motor via EMC cable glands.
● Arrange the exposed connecting cables in the terminal box so that the PE conductor has
an excess length and the insulation of the cable conductors cannot be damaged.
● Only remove insulation from the cable ends so that the insulation reaches up to the cable
lug, terminal, or wire end ferrule.
● Adapt the size of the cable lugs or wire end ferrules in line with the dimensions of the
terminal board connections and the cross-section of the power cable (use parallel
connection cables, if necessary).
● Make sure that the inside of the terminal box or connector is clean and free of cable
cuttings and moisture.
● Tighten all of the screws for the electrical connections (terminal board connections, with
the exception of the terminal strips) to the specified torque:
