in case of dismantling, do not grab the brackets, but rather the “solid“ parts such as the heat sink anche the plastic
cover. Remove the top bracket fi rst, then the bottom one to prevent the drive from falling down.

3.6 Electrical installation
Important
Important:
• before carrying out any maintenance work, disconnect the drive and the external control circuits from the power
supply by moving the main system switch to “off ”. Once power has been disconnected from the drive, wait at least
5 minutes before disconnecting the electrical cables;
• always make sure the motor has stopped completely. Motors that are still freely rotating may produce dangerous
voltages at the Power+ terminals, even when this is disconnected from the power supply.
