When connecting temperature sensors with three wires, a jumper must be inserted between
X53x.2 and X53x.4.

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
"+ Temp" and "- Temp".
NOTICE
Overheating of the motor through cables with too high a resistance
Cable length and cable cross-section can falsify the temperature measurement (10 Ω cable
resistance for a PT100 can falsify the measurement result by 10%). Damage to the motor
can result if the overheating is not detected.
• Use only cable lengths ≤ 300 m.
• For cable lengths >100 m, use cables with a cross-section of ≥1 mm
