All the monitoring devices fitted must always be connected!
The connection is made as described in the "Electrical connection" section.

DANGER
Risk of explosion due to overheating of the motor!
If the temperature limiter is connected incorrectly, there is a risk of explosion due to
overheating of the motor! Always connect the temperature limiter to a manual re-
activation lock. This means that a "release button" must be manually activated!
The motor is equipped with a temperature limit (1-circuit temperature monitoring). As
an option, the motor can be fitted with a temperature control and limit function (2-cir-
cuit temperature monitoring).
Depending on the version of the thermal motor monitoring, the following triggering
status must occur when the threshold value is reached:
▪ Temperature limiter (1 temperature circuit):
When the threshold is reached, deactivation with reactivation lock must take place!
▪ Temperature controller and limiter (2 temperature circuits):
When the threshold for the low temperature is reached, the motor can deactivate with
automatic reactivation. When the threshold for the high temperature is reached, the
motor must deactivate with reactivation lock!
CAUTION! Motor damage due to overheating! In the event of automatic reactiva-
tion, comply with the specifications for the maximum switching frequency and
switching break!
Connection of the thermal motor monitoring
▪ Connect the bimetallic strip via an evaluation relay. Relay "CM-MSS" is recommended
for this. The threshold is preset.
Connection values: max. 250 V(AC), 2.5 A, cos φ = 1
