Alternatively, two ring cable lugs without insulation for the parallel connection of two cables with a maximum cross-section
1)
of 50 mm² can also be connected to the threaded bolts respectively. Both cable lugs should be installed "back to back".
2) For ring cable lugs without insulation; ring cable lug M8; IP2XB guaranteed according to IEC 60529. Note: The restrictor collar
installed as standard for the purpose of touch protection must be used or adapted as required.
Risk of fire due to overheating when permissible cable cross-sections are exceeded
The internal overload monitoring function of the power module only protects the cable if this
is dimensioned/selected corresponding to the power module currents. Cables with an
excessively low cross-section can overheat and result in fire and smoke.
• Always use cables with adequate cross-sections. Take into account the routing type,
• If you select lower cross-sections, then you must ensure the appropriate level of cable
