Output Reactor (Option L08); Automatic Restart Function (Option L32); Cabinet Illumination And Service Socket In Closed-Loop Control Unit (Option L50); Disconnector At The Drive Output (Option L51) - Siemens SINAMICS SM150 6SL3810-7NN38-0AA1 Operating And Installation Instructions

3.6.12

Output reactor (option L08)

The output reactor limits the capacitive charge/discharge currents of motor supply cables.
Permissible cable lengths (shielded cables)
Without output reactor
Up to two parallel cables: 100 m
Three parallel cables: 80 m
3.6.13

Automatic restart function (option L32)

With option "Automatic restart" (L32), the system automatically restarts when the line supply
fails, irrespective of how long the line supply failure was. Alarms are acknowledged
automatically and the drive is restarted.
Voltage Sensing Module (VSM)
With the "Automatic restart" option, a Voltage Sensing Module VSM10 is integrated in the drive.
The VSM10 acquires the actual voltage values at the medium-voltage level upstream of the
circuit breaker.
When the medium voltage is restored after a power failure, this is detected by the open-loop/
closed-loop controllers via voltage transformers when the input-side circuit breaker has
dropped out. The voltage transformers should be located at the medium-voltage level upstream
of the circuit breaker.
For safety reasons, a time limit between the power failure and the maximum permissible power
restoration time is incorporated to ensure that the drive does not restart in an uncontrolled
manner. As a further warning, an acoustic signal is output when the drive restarts.
You can find further information on the Voltage Sensing Module (VSM10) in Section
"Description of the Components".
3.6.14

Cabinet illumination and service socket in closed-loop control unit (option L50)

One universal light with service socket is installed in each cabinet element for the trigger and
control section. The universal light and the power socket are supplied externally with power and
must be fused with max. 16 A.
The cabinet illumination can be switched on manually or automatically by means of an
integrated motion detector (default setting). If the light is switched on by the motion detector, it
stays on for three minutes. The mode is selected via the switch on the light.
3.6.15

Disconnector at the drive output (option L51)

With this option, a motor-operated isolator is integrated at the drive output.
If manual isolation between the drive output and drive motor is required for protection and
safety reasons, this can be achieved by means of the motor-operated isolator.
