General safety instructions

WARNING! Ignoring the following instructions can cause
physical injury or death, or damage to the equipment.
•
Only qualified electricians are allowed to install and maintain
the drive.
•
The drive and adjoining equipment must be properly earthed.
•
Do not work on a powered drive. After switching off the input
power, always allow the intermediate circuit capacitors 5
minutes to discharge before working on the drive, the motor or
the motor cable. Always ensure by measuring with a
multimeter (impedance at least 1 Mohm) that the drive is
discharged before beginning work.
•
The motor cable terminals of the drive are at a dangerously
high voltage when input power is applied, regardless of motor
operation.
•
There can be dangerous voltages inside the drive from
external control circuits even when the drive input power is
shut off. Exercise appropriate care when working on the unit.
