Note: The line current value
I
L
is a typical value which depends on the source impedance.
(1)
The aR semi-conductor fuses included as standard do not protect the drive power supply line. They must be combined with an
overload protection device (gG fuses, C type circuit-breaker, etc.) suitable for the installation configuration and located at the start
of the line.
(2)
The recommended AC supply cable cross-sections have been determined for single-core cable with a maximum length of 20 m.
For longer cables, take line drops due to the length into account.
(3) The motor cable cross-sections are given for information only for a current corresponding to the value of the
Ico current at 3 kHz in normal duty, 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 2 x [3 x 150 + PE] corresponds to 2 cables each consisting of 3 phase conductors
(cross-section 150 mm²) + earth conductors (see below).
(4) The earth (PE) conductor cross-section cannot be less than half the cross-section of a live conductor, with the same material
used. Example: The earth conductor cross-section for a live conductor 2x 240 mm² must be:
- 2x 120 mm²
- 2 x (3 x 40 mm2) when the earth conductor is divided by 3 (see above figure)
(5) For the Powerdrive MD2S 600T/750T/900T/1100T/1400T/1700T:
• The cables for each of the motor U/V/W phases must be distributed symmetrically over the U/V/W connection plates in each
drive cabinet
• In -B versions, the incoming line cables must be distributed symmetrically over the L1/L2/L3 connection plates in each drive
cabinet
