3.4.7.4
Voltage Sensing Module
The VSM10 Voltage Sensing Module measures the actual line voltage values. The connections
are wired internally to the customer terminal block.
3.4.7.5
DC/DC converter
DC/DC converters are used to provide a stable and reliable 24 V power supply for the TM15/
TM31 terminal module, the circuit breaker, and the SIMATIC S7 (optional).
3.4.7.6
SITOP Select
The SITOP Select is used to monitor and distribute the load current of the 24 V DC power
supply. The SITOP Select has four independent output channels. The output current of each
channel can be adjusted from between 3 A and 10 A.
Each channel has its own status signal.
● Channel 1 monitors the power supply for the SINAMICS modules.
● Channels 2 and 3 monitor the 24 V DC power supply in the power unit.
● Channel 4 is used to supply the customer terminals and the circuit breaker.
3.4.7.7
Sirius safety relay
The safety relay monitors the status of the Emergency Off circuit, and is used to implement a
safety-related shutdown when dangerous conditions occur. LEDs indicate the operating state
and the function.
