Contacting the shielding on the motor
Connect the shielding on the motor side to the PE junction that is located directly on the motor
housing.
For pre-assembled motor cables from ZIEHL-ABEGG, the shield connection terminal is provided with
a ring cable lug for the corresponding thread size.
When using non-prefabricated lines, implement the shielding connection by using a suitable shielding
connection system (e.g. Shield-Kon
®
).

Motor temperature monitoring (X-MT)
Information
The X-MT connection terminal is a standard part of the ZAdyn4B frequency inverter.
Information
The detection of over temperature of the motor doesn't cause a drive interruption. The current drive
will be completed.
If an over temperature of the motor will be detected at stop, there is no further drive possible.
The following sensor types can be used:
•
PTC thermistor (PTC in compliance with DIN 44082, switching point at 3500
Ω
)
•
Temperature sensor KTY84-130 (switching point adjustable: Parameter
Monitoring/R_P1P2
)
•
Thermal circuit breaker
The used sensor has to be parametrized in the menue

Information
If you do not use the temperature monitor and install a PTC thermistor (PTC in accordance with
DIN 44082) or a KTY84-130 temperature sensor, you must switch off the temperature monitor
(Monitors/P1P2=Off)
. Short-circuiting of the inputs P1 and P2 is detected as an error by the ZAdyn4B.
