1. Before Use
1. Important Safety Instructions
Drives and controllers are intended as components for professional incorporation into
complete systems. If installed incorrectly they may present a safety hazard. The drive uses
high voltages and currents, carries a high level of stored electrical energy, and is used to
control equipment which can cause injury. Close attention is required to the electrical
installation and the system design to avoid hazards either in normal operation or in the event
of equipment malfunction. System design, installation, commissioning/start­up and
maintenance must be carried out by personnel who have the necessary training and
competence. They must read this safety information and this guide carefully.
Responsibility
It is the responsibility of the installer to ensure that the equipment is installed correctly with
regard to all instructions given in this guide. They must give due consideration to the safety of
the complete system, so as to avoid the risk of injury both in normal operation and in the
event of a fault or of reasonably foreseeable misuse.
The manufacturer accepts no liability for any consequences resulting from inappropriate,
negligent or incorrect installation of the equipment.
Compliance with regulations
The installer is responsible for complying with all relevant regulations, such as national
wiring regulations, accident prevention regulations and electromagnetic compatibility (EMC)
regulations. Particular attention must be given to the cross­sectional areas of conductors,
the selection of fuses or other protection, and protective ground (earth) connections.
This guide contains instructions for achieving compliance with specific EMC standards.
All machinery to be supplied within the European Union in which this product is used must
comply with the following directives:
2006/42/EC Safety of machinery.
2014/30/EU: Electromagnetic Compatibility.
Electrical Hazards
The voltages used in the drive can cause severe electrical shock and/or burns, and could be
lethal. Extreme care is necessary at all times when working with or adjacent to the drive.
Hazardous voltage may be present in any of the following locations:
• AC and DC supply cables and connections
• Output cables and connections
• Many internal parts of the drive, and external option units
Unless otherwise indicated, control terminals are single insulated and must not be touched.
The supply must be disconnected by an approved electrical isolation device before gaining
access to the electrical connections.
The control terminal functions of the drive do not isolate dangerous voltages from the
output of the drive or from any external option unit.
The drive must be installed in accordance with the instructions given in this guide. Failure to
observe the instructions could result in a fire hazard.
