APPENDIX A

AK06-RD-

300…420 with output frequency 200 Hz

WARNING! Do not connect and disconnect live connections. Electronic
control units of variable speed drives contain components made on the
basis of metal-oxide semiconductor (MOS) technology that is not tol-
erant to static electricity. If you need to touch some MOS component,
ground your body and the tools to be used. When working with these
units, place them on current-conducting pads.
WARNING! Within 5 min after switching off the mains power, DC-link
capacitors retain the dangerous charge. Before working inside the cab-
inet, make sure that the capacitors are free of voltage. Default of the
above-listed requirements can lead to failures and premature failing of
the VSD.
