American Wire Gauge.
3)
Measured using 16 ft [5 m] shielded motor cables at rated load and rated frequency.
4)
The typical power loss is at normal load conditions and expected to be within
±
15% (tolerance relates to variety in voltage and cable
conditions).
Values are based on a typical motor efficiency. Lower efficiency motors will also add to the power loss in the adjustable frequency drive and vice
versa.
If the switching frequency is raised from nominal, the power losses may rise significantly.
LCP and typical control card power consumption values are included. Further options and customer load may add up to 30 W to the losses.
(Though typically only 4 W extra for a fully loaded control card or options for slot A or slot B, each).
Although measurements are made with state-of-the-art equipment, some measurement inaccuracy must be allowed for (
±
5%).
5)
The three values for the max. cable cross-section are for single core, flexible wire and flexible wire with sleeve, respectively. Motor and line cable:

8.2 Line Power Supply
Line power supply
Supply Terminals L1, L2, L3
Supply voltage 200–240 V ±10%
Supply voltage 380–480 V ±10%
Supply voltage 525–600 V ±10%
AC line voltage low/line drop-out:
During low AC line voltage or a line drop-out, the adjustable frequency drive continues until the intermediate circuit voltage
drops below the minimum stop level, which corresponds typically to 15% below the adjustable frequency drive's lowest rated
supply voltage. Power-up and full torque cannot be expected at AC line voltage lower than 10% below the adjustable frequency
drive's lowest rated supply voltage.
Supply frequency 50/60 Hz ±5%
Max. temporary imbalance between line phases 3.0% of rated supply voltage
True Power Factor (λ) ≥ 0.9 nominal at rated load
Displacement Power Factor (cos ϕ) Near unity (> 0.98)
Switching on input supply L1, L2, L3 (power-ups) ≤7.5 kW Maximum 2 times/min.
Switching on input supply L1, L2, L3 (power-ups) 11–75 kW Maximum 1 time/min.
Switching on input supply L1, L2, L3 (power-ups) ≥ 90 kW Maximum 1 time/2 min.
Environment according to EN60664-1 Overvoltage category III/pollution degree 2
The unit is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical Amperes,
240/500/600/690 V maximum.
