10.2 Choke
10.2.1 Optional input chokes (L1)
A three-phase mains choke is mandatory for sizes of ≥ 160 kW.
Use of mains chokes with an impedance of at least 3% is recommended.
The table below shows the minimum inductance values and current ratings with
the codes proposed by Gefran.
In case of a Master and Slave connection (400 kW to 1 MW devices) the use of
identical chokes (same inductance value and same current rating) for Master drive
and for each Slave drive is mandatory to ensure the correct distribution of current
over the drive input rectier bridges.

10.2.2 Optional external choke (L2)
On 400 kW to 1 MW devices, output chokes must be used: value and their techni-
cal characteristics MUST be the same for all the drive power modules (same
inductance value and same current rating) to garantee correct current sharing.
Cable lenght must be the same between the drive power modules.
