NOTICE
Motor damage due to incorrectly connected KTY temperature sensor
A KTY temperature sensor connected with incorrect polarity cannot detect if the motor
overheats. Overheating may result in damage to the motor.
• Connect a KTY temperature sensor with the correct polarity.
NOTICE
Overheating of the motor through jumpering the temperature sensor connections
Jumpering of the temperature sensor connections "+ Temp" and "- Temp" results in
incorrect measurement results. Damage to the motor can result if the overheating is not
detected.
• When using several temperature sensors, separately connect the individual sensors to
NOTICE
Device failure as a result of 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 separately
• Connect the cable shield at both ends to ground potential over a large surface area.
