Injury caused by short circuit
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.
Danger caused by incorrect cable routing
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.
Material damage caused by parts that can be magnetized
The use of magnetizable parts, e.g. ferrous cable clamps, is not permitted. Using parts and
components that can be magnetized can cause damage.
● Only use parts that consist of non-magnetic material.
Damage caused by incorrectly shrinking 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.
Damage caused by incorrectly opening doors
If you incorrectly open the doors, then this can damage the locking mechanism.
● Open the doors as described in Section "Preparing for use".
