Mains Supply; Motor Output And Motor Data - Danfoss VLT Refrigeration Drive FC 103 Operating Instructions Manual

Specifications
1)
For type of fuse see chapter 8.8 Fuses and Circuit Breakers.
2)
American Wire Gauge.
3)
Measured using 5 m screened motor cables at rated load and rated frequency.
4) The typical power loss is at normal load conditions and expected to be within
conditions).
Values are based on a typical motor efficiency. Lower efficiency motors will also add to the power loss in the frequency converter and vice versa.
If the switching frequency is raised from nominal, the power losses may rise significantly.
LCP and typical control card power consumptions 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)
The three values for the max. cable cross section are for single core, flexible wire and flexible wire with sleeve, respectively. Motor and mains
cable: 300 MCM/150 mm
6)
A2+A3 may be converted to IP21 using a conversion kit. See also Mechanical mounting and IP21/Type 1 Enclosure kit in the Design Guide.
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.

Supply voltage
Mains voltage low/mains drop-out:
During low mains voltage or a mains drop-out, the frequency converter continues until the intermediate circuit voltage drops
below the minimum stop level, which 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.
