Motor Terminal (Han 10E); Pin Assignment - Siemens ECOFAST Handbuch

Motor terminal (Han 10E)

Notes
Danger
Ensure that the wiring is carried out carefully and correctly. The temperature
sensor terminals must not be connected to 400 V AC. Otherwise motor star-
ters may be destroyed. There is potentially lethal danger!
For this reason, the motor line must be laid in such way that the cable cannot
get jammed or squashed!
Caution
Safe separation between 400 V AC and 24 V DC is only guaranteed on a motor
with safe separation of the temperature sensor circuit with respect to the stator
winding.
