Caution:
Before installing and putting this equipment into operation, please read the op-
eration manual YEG-TOE-S616-56.1, delivered on CD-ROM together with in-
verter.
1. Safety Precautions and Instructions for Use!
Please read these safety precautions and instructions for use thoroughly before installing
and operating this inverter. Also read all of the warning signs on the inverter and ensure
they are never damaged or removed.
➔
Live and hot inverter components may be accessible during operation. Removal of housing
components, 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 from about 5 minutes after the inverter is discon-
nected from the power. It is therefore necessary to wait for this time before opening its covers.
All of the main circuit terminals may still carry dangerous voltages. Ensure by measuring the
DC-Bus voltage that there is no dangerous voltage inside of inverter.
➔
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.
