1.11.4 Cable protection

To protect the supply cables against short circuit there must be fuses or motor circuit breakers (MCCBs) installed at the

mains end of the supply cable. Dimensioning of the fuses or MCCBs depends on the cable used and on the type of

primary fuses or MCCBs. If there are no other regulations, the values given in this section can be used to dimension

fuses (three phase 400V supply).

The overload protection of inverter protects both the supply and the motor cables. The fuses of the supply provide the

short circuit protection.

1.11.5 Cable length

The maximum motor cable lengths in the preceding table are based on 150% of inverter rated current (=current during

acceleration) and a 2.5 % voltage drop in the cable. For longer cables, the required conductor cross sectional area A

(mm2) is given by formula

×=

5.1

43.2

where l is the cable length (m)

is the motor current (A) at shaft power P

p is the allowed voltage drop in %

U is the nominal motor voltage

1.11.6 Du/dt filters

If inverter is not mounted on the crane, there has to be du/dt filter at motor supply. Also if total motor cable length (sum of

motor cables ) is over 100m with 002 –005 or over 200m with 007 –055, there has to be du/dt filter at motor supply.

m Du/dt filter should be as near inverter as possible

m Note! All control cables must be placed as far from the motor and braking resistor

cables as possible.
