X521 Three-Phase Line Supply Voltage Sensing Up To 100 V (Phase-To-Phase) - Siemens SINAMICS G130 Operating Instructions Manual

Note
In order to minimize noise emission, shielded cables should be used.
Note
The maximum cable length for a shielded cable – connected at both ends – to the
temperature sensor and to the analog inputs is 30 m.
