NORDAC SK400E Manual connect or
disconnect wires while power is applied to the circuit. Only qualified technicians should
perform maintenance on the SK400E.
CAUTION! There are highly sensitive MOS components on the printed circuit boards. These
components are especially sensitive to static electricity. To avoid damaging these
components, do not touch the circuit boards with metal objects or your bare hands.
DANGER! A charge may still remain in the DC-link capacitor with hazardous voltages even
after the power has been turned off. To avoid personal injury, do not remove the cover of the
AC drive until all “DISPLAY LED” lights on the digital keypad are off. Please note that there
are live components exposed when the AC drive is open. Be careful to not touch these live
parts.
CAUTION! Ground the SK400E using the ground terminal. The grounding method must
comply with the laws of the country where the AC drive is to be installed.
DANGER! The AC drive may be destroyed beyond repair if power is misapplied to the
input/output terminals. Never connect the AC drive output terminals U/T1, V/T2, W/T3
directly to the AC main circuit power supply.
