6.1 Safety instructions for electrical connections
Danger as a result of an insufficient degree of protection
The degree of protection can be diminished if the cable entries are inadequately sealed, e.g.
after making modifications to the top plate or base plate. Dirt and vermin can enter the device
while it is operational. When operated with an insufficient degree of protection, this can result
in death, serious injury and material damage.
● Close and seal the cable entries corresponding to the degree of protection.
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.
Danger caused by incorrect cable routing
Arcing can occur if cables are not routed in the supplied cable channels. This can result in
death, serious injuries or material damage.
● Use the cable ducts and cable entries on the roof to route the cables when electrically
connecting the cabinets.
