WARNING
Risk of electric shock if the temperature monitoring circuit is incorrectly connected
In the case of a fault, Temp-S and Temp-F circuits do not provide electrical separation with
respect to power circuits.
•
To connect Temp-S and Temp-F temperature monitoring circuits, use a TM120 or a
SME12x, for example. You therefore comply with the directives for electrical separation
according to DIN EN 61800-5-1 (previously electrical separation according to
DIN EN 50178).
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
the correct assignment of conductor colors.
Note
Observe the polarity
Carefully note the polarity when connecting the KTY.
