Table 8.10 Line Power Supply 3 x 525–690 V - Normal overload 110% for 1 minute, P37K-P90K
1) For type of fuse, see chapter 8.8 Fuses and Circuit Breakers.
2) American Wire Gauge.
3) Measured using 16.5 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: 300 MCM/150 mm

7) B3+4 and C3+4 may be converted to IP21 using a conversion kit. See also Mechanical mounting and IP21/Type 1 Enclosure kit in the Design
Guide.
