Temperature Sensor Interface; Connecting A Motor Holding Brake - Siemens SIMATIC ET 200pro Series Operating Instructions Manual

4.8.2

Temperature sensor interface

Description
The ET200pro FC-2 has a temperature sensor input that allows the real-time temperature of
the motor to be detected by the converter. You can connect a PTC, KTY84, Pt1000 or a
bimetal switch to the temperature sensor input.
The connections for the temperature sensor sensor to the motor temperature monitor is
integrated into the HAN Q motor connector on the front of the converter.
Electric shock from dangerous voltage on the sensor connections
The temperature sensor input is connected to the line supply potential and therefore
dangerous voltage is possible on the sensor connections. Touching live parts on the motor
cable and in the motor terminal box can lead to death due electrical shock.
• Power down the converter and disconnect all power cables from the converter before
• Insulate cables in the motor terminal box that are not used.
4.8.3

Connecting a motor holding brake

Electric shock due motor holding brake connections
The connections of the motor holding brake are energized with hazardous voltages.
Touching live components can result in death or severe injury.
• Disconnect the line voltage to the inverter and wait during the 5-minute discharge time
• Always keep the motor terminal box closed when line voltage is applied to the converter.
NOTICE
Risk of damage to equipment due to grounding of motor connecting cable
The connections of the motor holding brake are energized. If you ground the motor holding
brake connections, you will damage the converter.
• Use cables with suitable insulation.
• Isolate unused cables individually.
• The unused cables must not be grounded.
