DANGER!
1. A charge may still remain in the DC bus capacitors with hazardous voltages even if the power
has been turned off. To prevent personal injury, please ensure that the power is turned off and
wait ten minutes for the capacitors to discharge to safe voltage levels before opening the AC
motor drive.
2. Only qualified personnel familiar with AC motor drives is allowed to perform installation, wiring
and commissioning.
3. Make sure that the power is off before doing any wiring to prevent electric shock.
