Fuses
Fuses and cable cross-sections The specifications in chapter 3.4 are recommendations and refer to the application
• in control cabinets and machines,
• installation in the cable duct,
• max. ambient temperature +40 °C.
Selection of the cable cross-section For selection take into account the volta ge drop when a load is applied (to
DIN 18015 Part 1: ≤ 3%).
Cable and controller protection on the AC side
(L1, L2, L3)
• By means of standard commercial fuses.
• Fuses in UL-conform plants must have UL-approval.
• The rated voltages of the fuses must be rated according to the mains voltage
on site. The tripping characteristic is specified with ”H” or ”K5”.
Cable and controller protection on the DC side
(+UG, -UG)
• By means of recommended DC fuses.
• The fuses/fuse holders recommended by Lenze are UL approved.
For DC group drives or supply using a DC source: Observe the information given in part F of the Manual.
Connection of a braking unit When connecting the braking unit to the terminals +UG / -UG, the fuses and
cross-section given in chapter 3.4 do not apply. For the corresponding data, please
see the documentation of the braking unit.
Further information For cable and controller protection see the chapter ”Accessories” under
“Planning”.
Further standards The compliance with other standards (e.g.: VDE 0113, VDE 0289, etc.) remains the
responsibility of the user.
