Danger to life as a result of power cables overheating when permissible cross-sections are
fallen below
Excessively thin power cables can result in overheating. This can result in severe injury or
death due to fire and smoke.
• Only use power cables with sufficiently large cross-sections. Take into account the
• If smaller cross-sections are selected, you must ensure the appropriate level of
Note
Compliance with IPXXB degree of protection for Basic Line Modules 40 kW
Degree of protection IPXXB according to IEC 60529 for the Basic Line Module 40 kW is only
obtained when power cables with insulated end sleeves and cross-sections > 25 mm
used.
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.
If the apparent impedance of the line supply at the infeed point is not suitable, so that fuses
do not rupture in the specified time in the case of insulation failure (ground fault, fault to
frame), then you must use additional fault current protective devices RCD (RCCB or MRCD),
Type B to protect personnel and protect against fire.
