2.2 Safety Instructions
Following Handling Instructions
High voltages are present in the voltage stabilizer. Failure to follow this manual, the operating
instructions and the safety notes may lead to severe injury from electric shock. Only perform work as
described in this manual. Observe all safety notes.
Disconnecting the Device
Work on the inverter is only allowed if the power is disconnected and in compliance with the
guidelines that apply at the installation location.
• Disconnecting the device:
– grid voltage
• Ensure that the device cannot be reconnected.
• Ensure that no voltage is present in the system.
• Ground and short-circuit.
• Cover or safeguard any adjacent live components.
Error-Free Operation of the Voltage Stabilizer
In case of a ground fault, assume that grounded plant components are still live. Ensure there is no
voltage present before touching.
The operation of a damaged voltage stabilizer can lead to serious injuries through electric shock.
Operate the voltage stabilizer only if it is in a technically proper and operationally safe status.
Operate the voltage stabilizer only if there is no visible damage and check regularly for visible
damage. Ensure that all external safety equipment is freely accessible at all times and is checked for
proper functioning at least once a year.
Protective Conductor Connection
Also connect the grounding bridge when replacing the voltage stabilizer.
Warning Signs
Warning signs must be easily readable at all times and must be replaced in the event of
damage.
Storing the Documentation
Keep this documentation within close reach of the voltage stabilizer. It must be accessible to
service and maintenance personnel at all times.
