Danger from incorrect operation and work that is not carried out properly.
Serious personal injury and damage to property may result.
All the work and functions described in this document must only be carried out by a
▶
trained Fronius service technician.
Read and understand this document.
▶
Read and understand all the system component Operating Instructions, especially
▶
the safety rules.
WARNING!
Danger from electrical current.
Serious injuries or death may result.
Before starting work, switch off all devices and components involved, and discon-
▶
nect them from the grid.
Secure all devices and components involved so they cannot be switched back on.
▶
After opening the device, use a suitable measuring instrument to check that electri-
▶
cally charged components (such as capacitors) have been discharged.
WARNING!
Danger from electrical current due to inadequate ground conductor connection.
Serious personal injury and damage to property may result.
Always use the original housing screws in the quantity initially supplied.
▶
CAUTION!
Danger due to hot system components and hot coolant.
Serious burns may result.
Only perform all work described below when the coolant has cooled down to room
▶
temperature (+25 °C, +77 °F).
Only perform all work described below when the system components have cooled

down to room temperature (+25 °C, +77 °F).
CAUTION!
Risk of coolant escaping.
Serious damage to property may result.
If coolant ends up on the outside of the cooling unit, this should be removed
▶
immediately.
Make sure that no coolant ends up inside the machine.
