Electric Shock
Frequency inverter / servo drives contain dangerous voltages which can
cause death or serious injury. In operation, drive converters, depending on
their degree of protection, may have live, uninsulated, and possibly also
moving and hot surfaces.
In case of inadmissible removal of the required covers, of improper use,
wrong installation or maloperation, there is the danger of serious personal
injury and damage to property.
Only Qualified Electro-Personnel
All work of installation and start-up may only be done by qualified personnel.
According to this manual qualified staff means those who are able to recog-
nise and judge the possible dangers based on their technical training and
experience and those with knowledge of the relevant standards and who are
familiar with the field of power transmission and safety technology.
In the range of safety technology, authorized personnel must be confirmed in
written document by KEB.
Note capacitor discharge time
Before any installation and connecting work, the unit must be disconnected
from mains and secure it accordingly.
After disconnecting the frequency inverter/servo drive, the DC link capacitors
are still charged with high voltage for a short time. Therefore, work on the
device may be carried out until 5 minutes after switching off.
Electrostatic-discharge-sensitive components
Use antistatic wrist strap for any working on the device or take other appro-
priate measures for static discharge.
