Danger due to defective seals
When working on the device, seals at the doors, roof panels as well as front, rear and side
panels can be damaged. Operation with defective seals can result in death, serious injury or
material damage.
● Replace the defective seals before commissioning. Observe the environmental conditions
stated in the technical data.
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.
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.
Material damage caused by high transition resistances
Cables connected to the connection point that are not in compliance with the applicable
regulations represent a high electrical transition resistance that can cause thermal damage
(contact erosion) during operation.
● Tighten the screws with the required torque.
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 shrinking cable terminations
When connecting line and motor-side power cables, when shrinking the cable terminations,
other control cables can be damaged in the adjacent/surrounding cable ducts.
● When shrinking, ensure not to damage cables in the surrounding cable channels.
