2.1 Safety Precautions
Electric Shock
High voltages are present in the Transformer Compact Station. Failure to adhere to the safety
messages will lead to death or serious injuries as a result of electric shock.
• All work must be carried out as described in this manual. Observe all safety precautions.
Observe all safety precautions included in this document and the documentation of the
components.
• Do not touch any live components of the Transformer Compact Station or the medium-voltage
grid. Comply with all applicable safety regulations for handling electrical installations and the
medium-voltage grid.
• When electrical work is being carried out, a second person must be present at all times. In the
event of an unforeseen accident involving electricity, this person must be able to switch off the
electricity supply and provide assistance.
In the event of an earth fault, remember that plant components which are presumed earthed may still
be live. Failure to adhere to the safety messages will lead to death or serious injuries as a result of
electric shock.
• Ensure that no voltage is present before touching any part of the plant.
• Wear personal protective equipment.
Operating a damaged Transformer Compact Station can lead to hazardous situations that result in
death or serious injuries due to electric shock.
• Operate the Transformer Compact Station only if it is in safe and good working order.
• Regularly check the Transformer Compact Station for visible damage.
• Operate the Transformer Compact Station only if there is no visible damage.
• Make sure that all external safety equipment is freely accessible at all times.
• Make sure that all safety equipment is in good working order.
Environmental Hazard
Ensure that escape routes are not blocked.
• The escape routes must be dimensioned sothat the persons working on the
Transformer Compact Station can escape quickly in dangerous situations.
• Escape routes must not be blocked.
• The minimum passage width of the escape route must comply with national standards.
In Germany, the minimum passage width is 800 mm.
Moisture and dust penetration can damage the Transformer Compact Station.
• Do not open the low-voltage area of the Transformer Compact Station if it is raining.
• Only perform maintenance in a dry and dust-free environment.
