SPECIALIZED PERSONNEL MUST CARRY OUT ANY WORK ON THE EQUIPMENT.
BOTH AT THE BEGINNING AND END OF A REPAIR CHECK THE EQUIPMENT INSULATION LEVELS.
DISCONNECT THE ELECTRONIC BOARDS WHEN MEASURING THE INSULATION.
The insulation-measuring device will have 500 V DC and will be applied to the following points of the circuit:
- Rectifier input-earth: Ra> 50 Mohms
- Rectifier output-earth: Ra> 50 Mohms
- I2 Switch - Rectifier output: Ra> 50 Mohms
- Control circuit - Earth: Ra> 50 Mohms
In the event that lack of insulation is observed it is likely that this is due to the accumulation of metal dust on the inside of
the equipment.
BOTH AT THE BEGINNING AND END OF A REPAIR, BLOW THE INSIDE OF THE EQUIPMENT WITH
COMPRESSED AIR.
ELECTROMAGNETIC COMPATIBILITY (CEM).
The user is responsible for the installation and use of the welding material according to the instructions in this manual
