Siemens SINAMICS SM150 - Cabinet Illumination and Service Socket in Closed-Loop Control Unit (Option L50); Disconnector at the Drive Output (Option L51); Circuit Breaker at the Drive Output (Option L52); EMERGENCY STOP Category 1 (Option L60)

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.
3.6.16 Circuit breaker at the drive output (option L52)
With this option, a circuit-breaker is integrated at the drive output. If isolation between the drive
output and drive motor is required for protection and safety reasons, this can be achieved by
means of the circuit-breaker. The circuit-breaker is controlled from the drive controller. When
an ON command is issued, the output-side circuit-breaker is activated along with the auxiliary
equipment. When an OFF command is issued, the circuit-breaker is deactivated.
3.6.17 EMERGENCY STOP Category 1 (option L60)
Emergency Off, stop category1 (24 VDC) for controlled stop according to IEC60204.
In the standard version, Emergency Off stop category 0 is set for an uncontrolled stop. It also
has a function for disconnecting the drive from the power supply via the circuit-breaker. The
motor coasts down. The Emergency Off, stop category 1 function includes rapid stopping of the
drive using a deceleration ramp to be parameterized by the user. Voltage is then disconnected
from the drive as described for Emergency Off, stop category 0.
The EMERGENCY OFF button with protective collar is installed in the drive cabinet door.
