A.3
Temperature sensors for SINAMICS components
WARNING
Electric shock in the event of voltage flashovers on the temperature sensor cable
Voltage arcs to the signal electronics can occur for motors without electrical separation of
the temperature sensors, which can result in death or serious injury when there is contact.
• Use temperature sensors that satisfy the specifications of the protective separation in
accordance with IEC 61800-5-1.
• If protective separation cannot be guaranteed (with linear motors or third-party motors,
for example), use a Sensor Module External (SME120 or SME125) or the TM120
Terminal Module.
The following table provides an overview of the SINAMICS drive system components
available with temperature sensor connections.
