5) Measured using 5 m screened motor cables at rated load and rated frequency.
6) Enclosure sizes A2+A3 can be converted to IP21 using a conversion kit. See also chapter 3.7 Mechanical Planning.
7) Enclosure sizes B3+B4 and C3+C4 can be converted to IP21 using a conversion kit. See also chapter 3.7 Mechanical Planning.

Supply voltage
Mains voltage low/mains drop-out:
During low mains voltage or a mains drop-out, the frequency converter continues until the DC-link voltage drops below the
minimum stop level. The minimum stop level corresponds typically to 15% below the frequency converter's lowest rated supply
voltage. Power-up and full torque cannot be expected at mains voltage lower than 10% below the frequency converter's lowest
rated supply voltage.
