: Technicians must verify polarity with a multimeter and ensure DC bus capacitors are discharged before installation to avoid electric shock [1, 7].
IP20 (protected against solid objects >12mm, but must be housed in an enclosure to protect against dust and moisture).
: Terminal bolts should be torqued to 12 Nm to ensure stable connections under vibration [1].
