Danger to life as a result of overheated motor cables if permissible cross-sections are fallen
below
Motor cables with inadequate cross-section can cause components to overheat. This can
result in severe injury or death due to fire and smoke.
• Use cables that correspond to the Motor Module currents.
• If smaller cross-sections are selected, you must ensure the appropriate level of
Note
Compliance with the IP20 degree of protection for Basic Line Modules 40 kW
The 40 kW Basic Line Module only has an IP20 degree of protection when used with power
cables with insulated end sleeves and a cross-section > 25 mm
Note
Cross-section of the protective conductor
The cross-section of the PE conductor must be selected according to DIN EN 60204-1, DIN
EN 61800-5-1 and VDE 0100-540 (IEC 60364-5-54). Some components result in an
increased leakage current. In this case, regulation EN 61800-5-1 must be taken into account.
Note
Selection of the line supply conductor
When selecting the line supply conductor, note the loop resistance so that the relevant
protective components (line fuse, RCCB, etc.) function properly and that no hazardous shock
currents or voltages occur in the event of a fault.
