General safety instructions
WARNING! All electrical installation and maintenance work on the
drive should be carried out by qualified electricians.
The drive and adjoining equipment must be properly earthed.
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.
The motor cable terminals of the drive are at a dangerously high
voltage when mains power is applied, regardless of motor
operation.
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 with the unit. Neglecting
these instructions can cause physical injury and death.
WARNING! There are several automatic reset functions in the
drive. If selected, they reset the unit and resume operation after a
fault. These functions should not be selected if other equipment is
not compatible with this kind of operation, or dangerous situations
can be caused by such action.
More Warnings and Notes are printed at appropriate instances
along the text.
WARNING! Warning aims to draw special attention to a partic-
ular issue.
Note: Note gives additional information or points out
more information available on the subject.
