IMPORTANT INFORMATION
Specific characteristics of the materials used must be defined during the product quotation process.
The cabin must initially be powered on without any load, i.e., without any transformer connected to the output, to verify that it is in compliance for operation.
Before carrying out any work, make sure the cabin structure has been grounded.
