Note: The line current value
I
L
is a typical value which depends on the source impedance. The higher the impedance. the lower the
current.
(1) gG fuse or equivalent solution (fuses connected in parallel. preferably C type circuit-breaker. etc). This protection must always
be connected in series with aR semi-conductor fuses.
(2) Semiconductor aR fuses do not ensure the protection of the drive power supply line and must always be associated with a
protection device against overload. localized at the head of the line.
(3) The recommended mains cable cross-sections have been determined for single-core cable with a maximum length of 20 m. For
longer cables. take line voltage drop into consideration due to high cable length.
(4) The motor cable cross-sections are given for information only for a current corresponding to the value of the
Ico current at 3 kHz. a maximum length of 50 m. output frequency less than 100 Hz and an ambient temperature
of 40°C.
The recommended motor cables are shielded multicore type
.
The values supplied are typical values.
Example: Cable cross-section of 3 x (3 x 185 + 95) corresponds to 3 cables each consisting of 3 phase conductors
(cross-section 185 mm²) + earth conductors (cross-section 95 mm²).
