Electrical connection
9.3 System integration
9.3.9 Signal connection
No direct connection of the temperature monitoring circuits
Risk of electric shock if the temperature monitoring circuits are incorrectly connected
In the case of a fault, circuits Temp‑S and Temp‑F do not provide safe electrical separation with
respect to the power circuits.
• Use the TM120 or SME12x to connect temperature monitoring circuits Temp‑S and Temp‑F.
Correctly connecting temperature sensors
NOTICE
Motor destroyed as a result of overtemperature
The motor can be destroyed as a result of overtemperature if you do not correctly connect the
temperature sensors.
• When connecting temperature sensor cables with open conductor ends, pay attention to
Note
Observe the polarity
Carefully note the polarity when connecting the KTY.
Temperature sensor connection - standard
Connect the signal cable as follows:
• Using a plug connector at the SME12x (Sensor Module External)
• With open cable ends at the TM120

WARNING
You therefore comply with the directives for safe electrical separation according to DIN EN
61800‑5‑1 (previously safe electrical separation according to DIN EN 50178).
