NOTICE
Device failure due to unshielded or incorrectly routed cables to temperature sensors
Unshielded or incorrectly routed cables to temperature sensors can result in interference
being coupled into the signal processing electronics from the power side. This can result in
significant disturbance of all signals (fault messages) up to failure of individual components
(destruction of the devices).
• Only use shielded cables as temperature sensor cables.
• If temperature sensor cables are routed together with the motor cable, use twisted-pair,
• Connect the cable shield at both ends to ground potential over a large surface area.
• Recommendation: Use suitable Motion Connect cables.
NOTICE
Risk of motor overheating due to incorrectly connected KTY temperature sensor
A KTY temperature sensor connected with incorrect polarity cannot detect if the motor
overheats.
• Make sure that you connect the KTY temperature sensor with the correct polarity.
Note
The temperature sensor connection can be used for motors that are equipped with a KTY84-
1C130 or PTC probe in the stator windings.
Note
EP terminals only for Safety Integrated Basic Functions
The function of the EP terminals is only available when Safety Integrated Basic Functions
are enabled.
Note
Safety Integrated Function Manual
Detailed and comprehensive instructions and information for the Safety Integrated functions
can be found in the associated Function Manual. This manual is available as additional
documentation on the customer DVD supplied with the device.
