Safety instructions
Caution:
Any work on the control equipment, e.g. installation, connection, maintenance, may only be performed, if
−
the system is de-energized,
−
protected against restarting, and
−
all drives are at standstill!
Before starting to work test the isolation using a suitable tool.
Danger:
In activated condition electrical equipments and machines contain energized bare conductors or rotating
parts. When covers and prescribed protective devices are removed, this might lead to injury of persons
or property damage in case of incorrect handling and maintenance or in case of any use not in
accordance with the regulations.
A further risk with power electronic equipment, which not every expert is acquainted with, is that there is
still electric energy in the equipment even after disconnection of the supply voltage (capacitor
charging!). When the required discharging time has elapsed the equipment must be checked for
residual voltage prior to starting any work.
Attention:
Electrical systems and machines may only be
installed,
−
connected,
−
commissioned,
−
serviced and
−
operated by experts who are trained applying the applicable safety and installation regulations.
Have any work checked by trained experts. The experts must be authorized for the required work by the
person in charge of system safety.
Experts are persons who have the necessary training and experience are acquainted with the respective
applicable standards, regulations and accident prevention regulations, are familiar with function and
operating conditions of electrical drive systems, are able to recognize and avoid any danger.
Control, locking functions, monitoring and protective functions (thermal motor protection, speed monitor,
overcurrent, earth fault, etc.) must not be deactivated, not even in trial operation.
The system may only be installed and operated in accordance with the documented layout. Use in
compliance with the regulations. Any other use is prohibited!
Storage regulations:
The regulations for storing electrical systems must be observed. Please request these
regulations if required, or take them out of the technical data!
