Safety
WARNING! All electrical installation and maintenance work on the drive
should be carried out by qualified electricians only.
WARNING! The drive and adjoining equipment must be properly
grounded.
WARNING! Do not attempt any work on a powered drive. After
switching off the mains, always allow the intermediate circuit capacitors
5 minutes to discharge before working on the drive, the motor or the
motor cable. It is good practice to check (with a voltage indicating
instrument) that the drive is in fact discharged before beginning work.
WARNING! The motor cable terminals of the drive are at a dangerously
high voltage when mains power is applied, regardless of motor
operation.
WARNING! There can be dangerous voltages inside the drive from
external control circuits even when the drive mains power is shut off.
Exercise appropriate care when working on the unit. Neglecting these
instructions can cause physical injury or death.

how to avoid the danger. The warning symbols are used as follows:
