ATTENTION

• The installation, commissioning and maintenance of these drives may only be carried out by

experienced personnel who are thoroughly familiar with the functioning of the equipment and the

entire machine.

• The devices feature DC-bus capacitors that are energized even when the mains supply is switched

off. For this reason wait at least 5 minutes after switching off the mains supply before you open the

device and start working on it. Take care that you do not touch any live parts.

• Do not apply mains voltage to the output terminals U/T1, V/T2 and W/T3.
