2.7 Working on device/hazards through residual voltage
Before working on previously installed devices, separate them from the mains
and secure them against reconnection.
Danger!
Through use of capacitors in the ZAdyn4C danger of death exists even after switching
off the ZAdyn4C through directly touching the energized parts or due to parts that have
become energized due to faults.
After waiting at least 3 minutes work can be performed on the ZAdyn4C.
The safe isolation from the supply must be checked using a two-pole voltage detector.
Danger!
It is generally forbidden to carry out work on electrical live parts. Protection class of the
device when open is IP 00! It is possible to touch hazardous voltages directly.
2.8 Modifications / interventions in the device
For reasons of safety, no unauthorized interventions or modifications may be made on
the device .
All planned modifications must be authorized by the manufacturer in writing.
Use only genuine spare parts / genuine wearing parts / genuine accessories from the
ZIEHL-ABEGG SE.These parts were specifically designed for the device. There is no
guarantee that parts from non-original sources are designed and manufactured in
correspondence with load and safety requirements.
Parts and special equipment not supplied by the ZIEHL-ABEGG SE are not approved for
use.
2.9 Operator’s obligation of diligence
The device has been designed and constructed with consideration of a hazard analysis
and after carefully selecting the harmonized standards to be complied with as well as
additional technical specifications. It thus complies with the state-of-the art and ensures
the highest degree of safety.
However, this safety can only be implemented in operational practice if all measures
necessary for this purpose are taken. The operator of the installation has the obligation
of due diligence to plan these measures and monitor their implementation.
In particular, the operator must ensure that
•The device is only used as intended (cmp. chapter "Product overview" concerning
this)
•The installation is operated solely in a flawless, functional condition and that espe-
cially the safety devices are periodically checked for their properly functioning con-
dition
•The required personal safety gear is available to and used by the operating, main-
tenance and repair personnel
•The operating instructions are always readily available at the location where the
frequency inverter is being used, are complete and are in legible condition
•Only sufficiently qualified and authorized personnel operate, maintain and repair the
device
