Option L08 (Motor reactor) / L09 (2 motor reactors in series)

Option L08 is available for SINAMICS G150, SINAMICS S120 Cabinet Modules (currently only for air-cooled units /
option for liquid-cooled units will be available soon), SINAMICS S150.
Option L09 is available for SINAMICS S120 Cabinet Modules / Booksize Cabinet Kits.
Option L08 (motor reactor) is shipped pre-wired or pre-assembled with bar connectors with the cabinet unit. On
SINAMICS G150 cabinets, SINAMICS S120 Cabinet Modules with Chassis frame sizes FX and GX, and on
SINAMICS S150 cabinets, the motor reactor is positioned inside the cabinet underneath the power unit. For
SINAMICS S120 Cabinet Modules with Chassis frame sizes HX and JX, an additional, 600 mm-wide cabinet next to
the Motor Module is required.
On SINAMICS S120 Cabinet Modules with Booksize Cabinet Kits, the motor reactor is also positioned inside the
Booksize Base Cabinet and assigned to the relevant Booksize power unit.
Option L09 comprises a series connection of two motor reactors for SINAMICS S120 Cabinet Modules with Booksize
Cabinet Kits. It is not possible to install more than two motor reactors for each Motor Module in Booksize format.
Double Motor Modules in Booksize format can only be equipped with a single motor reactor (option L08) as standard.
The motor reactors are installed inside each Cabinet Kit according to the EMC zone concept with a shielding. This
does not make them less accessible. To assist connection of motor cables, the connection area of the Booksize Base
Cabinet includes terminals and shield bonding facilities for shielded motor cables. The wiring from the connection
area to the reactor and on to the Motor Module is already provided as standard. The cabinet is specially constructed
to ensure electromagnetic compatibility.

Permissible motor cable lengths when Booksize Cabinet Kits are equipped with one or two motor reactors
The motor reactors of the Booksize Cabinet Kits are suitable for a maximum pulse frequency of 4 kHz. The maximum
permissible output frequency when motor reactors are used is 120 Hz.
For further information about restrictions on motor cable lengths with units in Chassis and Booksize format, please
refer to section "Maximum connectable motor cable lengths" in chapter "General Information about Built-in and
Cabinet Units SINAMICS S120".

Option L25 (Circuit breaker in a withdrawable unit design)

This option is available for SINAMICS S120 Cabinet Modules (air-cooled and liquid-cooled units).
Line Connection Modules with an input current of > 800 A are equipped as standard with fixed-mounted circuit
breakers. With option L25, these circuit breakers are supplied as a withdrawable version so that the breakers can be
implemented as a visible disconnection point.
The withdrawable breaker version should be used for applications which require a high level of plant availability or a
high operating frequency. The advantage of the withdrawable version is that the breakers can be replaced quickly.
