Safety Precautions and Instructions
General
Please read these safety precautions and instructions for use thoroughly before installing and oper- ating this inverter. Also read all of the warning signs on the inverter and ensure they are never dam- aged or removed.
Live and hot inverter components may be accessible during operation. Removal of housing compo- nents, the digital operator or terminal covers runs the risk of serious injuries or damage in the event of incorrect installation or operation. The fact that frequency inverters control rotating mechanical machine components can give rise to other dangers.
The instructions in this manual must be followed. Installation, operation and maintenance may only be carried out by qualified personnel. For the purposes of the safety precautions, qualified personnel are defined as individuals who are familiar with the installation, starting, operation and maintenance of frequency inverters and have the proper qualifications for this work. Safe operation of these units is only possible if they are used properly for their intended purpose.
The DC bus capacitors can remain live for about 5 minutes after the inverter is disconnected from the power. It is therefore necessary to wait for this time before opening its covers. All of the main cir- cuit terminals may still carry dangerous voltages.
Children and other unauthorized persons must not be allowed access to these inverters.
Keep these Safety Precautions and Instructions for Use readily accessible and supply them to all persons with any form of access to the inverters.
Intended Use
Frequency inverters are intended for installation in electrical systems or machinery.
Their installation in machinery and systems must conform to the following product standards of the Low Voltage Directive:
EN 50178,
EN
Part 1: General Requirements (IEC
Please note: Includes Corrigendum of September 1998
EN
(IEC 950, 1991 + A1, 1992 + A2, 1993 + A3, 1995 + A4, 1996, modified)
CE marking is carried out to EN 50178, using the line filters specified in this manual and following the appropriate installation instructions.
Transportation and storage
The instructions for transportation, storage and proper handling must be followed in accordance with the technical data.
Installation
Install and cool the inverters as specified in the documentation. The cooling air must flow in the specified direction. The inverter may therefore only be operated in the specified position (e.g. upright). Maintain the specified clearances. Protect the inverters against impermissible loads. Com- ponents must not be bent nor insulation clearances changed. To avoid damage being caused by static electricity, do not touch any electronic components or contacts.
