Fuses and cable cross-sections The specific ations in chapter 3.3.4 are recommendations and refer to
•
the use in control cabinets and machines
•
installation in cable ducts,
•
max. ambient temperature of +40 °C.
Selection of the cable cross-section Please consider the voltage drop under load (according to DIN 18015, part 1: ≤ 3%).
Cable and controller protection on the AC side
(L1, L2, L3)
•
By means of standard commercial fuses.
•
By means o f fuses in UL-conform plants must have UL approval.
•
The rated voltages of the fuses must be di mensioned according to the mains
voltage at the site. The activation characteristic is defined with ”H” or ”K5”.
Cable and controller protection on the DC side
(+UG, -UG)
•
By means o f recommended DC fuses.
•
The fuses/fuse holders recommended by Lenze are UL a pproved.
For DC group drives or supply using a DC source: Please observe the notes in part F of the systems manual.
