L22, elimination of the three-phase commutating reactor

Category
Supplementary circuits
Function
A three-phase commutating reactor is not mounted in the drive cabinet, it is also not
supplied.
On the plant/system side, by using an appropriately large inductance, it must be ensured that
disturbances fed into the line supply as a result of voltage peaks during converter
commutation are minimized. This is generally guaranteed if the converter has its own
converter transformer with an adequate short-circuit voltage (6 to 10%).
Note
This option cannot be combined with option Y03 (no auxiliary power supply available).
This option cannot be combined with option L00 (radio interference suppression filters).

L50, cabinet lighting and service socket outlet

Category
Supplementary circuits
Function
The panel has its own universal lamp; the control cabinet also has a service socket outlet.
When the cabinet door is opened, a motion sensor automatically switches on the light. The
power supply (1 AC 230 V, 50/60 Hz) must be available externally from a grounded line
supply and fused/protected in the low-voltage distribution on the plant side with maximum
16 A. A combined miniature circuit breaker/residual current-operated circuit breaker
13 A/30 mA is installed in the cabinet.
When the supply voltage for the cabinet lighting is connected, dangerous voltages are
present in the cabinet unit even when the main switch is open.
