Signal connection

No direct connection of the temperature monitoring circuits
Risk of electric shock when incorrectly connecting the temperature monitoring circuit
In the case of a fault, circuits Temp-S and Temp-F do not provide safe electrical separation
with respect to the power components.
• Use, for example, the TM120 or the SME12x to connect the 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.
