Protection
Fuses and cable cross-sections The specifications in chapter 3.6 are recommendations and refer to the application
- in control cabinets and machines,
- installation in the cable duct,
- max. ambient temperature + 40 •C,
- as single drive with matching motor.
Selection of the cable cross-section For selection take into account the voltage drop when being loaded
(to DIN 18015 part 1:
≤
3 %).
Protection of cables and controller on
the AC side (L1, L2, L3) - By standard commercial fuses.
- Fuses in UL-conform plants must have UL approval.
- The rated voltages of the fuses must be dimensioned according to the mains voltage
at the site. The activation characteristic is defined by ”H” or ”K5”.
Protection of cables and controller on
the DC side (+ U
G
, -U
G
)
- By means of recommended DC fuses.
- The fuses/fuse holders recommended by Lenze are all UL-approved.
For DC group drives or supply via DC
source Observe notes in Part F.
Connection of a brake unit If the unit is connected to the terminals + U

/ -U
G
, the fuses and cross-sections
indicated in chapter 3.6 are not valid. These unit-specific data can be obtained from the
technical documentation for the brake unit.
Further information For protection of cables and controllers, see chapter ”Accessories”.
Further standards The compliance with other standards (e.g. VDE 0113, VDE 0289, etc.) remains in the
responsibility of the user.
4.2.7.2 Motor connection
For EMC safety reasons we recommend the use of screened motor cables.
Note!
The screening of the motor cable is only required to comply with existing standards
(e.g. VDE 0160, EN 50178).
