1.4.2 General information
• Only persons who are qualified and trained for the use and operation of the equipment may
work on this equipment or within its proximity. The persons are qualified if they have
sufficient knowledge of the assembly, transportation, installation and operation of the
equipment as well as an understanding of all warnings and precautionary measures noted in
these instructions. The user must also observe local safety regulations.
• Before installing and commissioning the drive, read carefully this documentation and strictly
observe all technical, safety and wiring information, including identifying labels placed on the
drive (ratings). In case of doubt contact the Parker Hannifin service centre.
• Drives are to be intended as components for use in machine or systems. Therefore they can be
used only in machine or systems that are in compliance with the low voltage directive
73/23/CEE (modified by 93/68/CEE) and with the electro-magnetic compatibility directive
89/336/CEE.
• Electronic equipments are generally not “fail-safe” components. Therefore the machine
manufacturers should carry out a risk analysis for the whole machine in order to ensure that
moving parts (motors) cannot bring personal injury in case of failures of electronic devices.
