WARNING
Short-circuits
Damaged cables, or their improper routing, can cause damage to property and personal
injury.
● Only use cables that are completely intact and not damaged. Correctly route the cables.
Do not interchange input and output terminals.
● Make sure that a short-circuit cannot occur on the power cables due to failure of the
insulation as a result of incorrect cable installation.
● Check the electrical connections after service work.
WARNING
Incorrect laying of cables
Failure to use the supplied cable ducts for laying the cables can lead to flashovers. This can
result in death, serious injuries or material damage.
To connect the cables between the cabinets, use the cable ducts and the cable entries on
the roof. Lead the cables from here to the next cabinet.
NOTICE
Using magnetizable parts
The use of magnetizable parts, e.g. ferrous cable clamps, is not permitted. The use of
magnetizable parts can damage the converter.
Only use parts that consist of non-magnetic material.
NOTICE
Danger of thermal damage
Inadequately fastened cables at the connection point represent a high electrical transfer
resistance that can cause thermal damage (contact erosion) during operation.
Tighten the screws with the specified torque.
NOTICE
Improper shrinking of cable terminations
If you are connecting the mains and motor-side power cables, when shrinking the cable
terminations, other control lines and fiber-optic cables in the surrounding cable channels can
become damaged.
When shrinking, ensure not to damage cables in the surrounding cable channels.
