Installation
WARNING! All electrical installation and maintenance work on the drive should be
carried out by qualified electricians only.
The drive and adjoining equipment must be properly earthed.
Do not work on a powered drive. Before installation, switch off the mains and other
dangerous voltages (eg. from external control circuits) to the drive. After switching off
the mains, always allow the intermediate circuit capacitors 5 minutes to discharge
before starting work on the frequency converter. It is a good practice to check (with a
voltage indicating instrument) that the drive is in fact discharged before beginning
work.
There may 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 may cause physical injury or death.
WARNING! The component boards of the drive contain integrated circuits that are
extremely sensitive to electrostatic discharge (ESD). Wear an earthing wrist band
when handling component boards. Do not touch the boards unnecessarily. Do not
remove any board from its antistatic packaging until required.
