● Do not remove any covers.
Risk of burns due to hot component surfaces
Certain components (e.g. heat sinks and reactors) can become very hot during operation.
These components can remain hot for a long time after operation. Contact can result in serious
injury, such as skin burns.
● After the device has been shut down, do not touch any hot components.
Skin burns when touching the roof panel
Certain components, such as busbars and resistors etc., can become very hot in operation.
Until the heat has been fully dissipated, the roof panel in the front area can still be very hot even
after the device has been shut down.
Touching hot surfaces can cause burns to the skin.

● Always take the appropriate precautions before touching any parts and components.
Risk of injury at places that are difficult to access
If you do not use appropriate protective equipment when working in places that are difficult to
access you are at risk of injury. For example, sharp edges and splinters can cause injuries to
the head and skin. If you carry out work in the upper section using unsuitable ladders or similar,
you can fall and injure yourself.
