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 frequency converter, 
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 on the unit. Neglecting 
these instructions can cause physical injury or death.
