cause high frequency interference, which may require the user to take appropriate measures.
An appropriate measure would be the inclusion of a recommended line filter.
1.5 Certifications
1.5.1 European EMC guideline
If the NORDAC SK 700E is installed according to the recommendations in this instruction manual, it
meets all EMC directive requirements, as per the EMC product standard for motor-operated systems
EN 61800-3.
(See also Chapter 8.3 Electromagnetic compatibility [EMC].)
1.5.2 UL and cUL certification
(Used in North America)
“Suitable for use on a circuit capable of delivering not more than 5000 rms symmetrical
amperes, 380…480 Volts (three phase)” and “when protected by 600V J class fuses”
(Frequency inverter size 1 … 4), resp. „when protected by 600V R class fuses or faster”
(Frequency in
verter size 5 … 7) as described in Chapter 7.4."
Suitable for use on a circuit capable of delivering not more than 5000A (symmetrical),
380...460 Volts (three phase) and when protected by "600V J class fuses" (Size 1 ...4
frequency inverters) or a "600V R class fuse or faster" (Size 5 ... 7 frequency inverters) as described in Chap. 7.4.
NORDAC SK 700E frequency inverters have motor overload protection.
