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
temperature monitoring circuits. 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).
Correctly connecting temperature sensors
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
the correct assignment of conductor colors.
Note
Observe the polarity
Carefully note the polarity when connecting the KTY.
The following shows various connection variants for the temperature sensors. These
illustrations apply to the operation of 1FN3 linear motors with the SINAMICS S120 drive
system. The IDs A, B or C are used to identify the conductor assignments of the temperature
sensor cables in the following tables.
