1.5.1 Proper intended use
WARNING
Unintended use of the servo geared motors
If you do not use the servo geared motors for their proper intended use, then there is a risk of
death, severe injury and/or material damage.
• Only use the servo geared motors for their proper intended purpose.
• Ensure that the conditions at the installation site comply with all the rating plate data.
