minimum specifications of IEC / EN 60079–1 is not permissible.
This can result in death, serious injury or material damage.
● Obtain the gap dimensions of the electrical machine from the manufacturer for the repair
Through careful and regular maintenance, inspections, and overhauls you can detect faults at
an early stage and resolve them. This means that you can avoid consequential damage.
Operating conditions and characteristics can vary widely. For this reason, only general
maintenance intervals can be specified here. Maintenance intervals should therefore be
scheduled to suit the local conditions (dirt, starting frequency, load, etc.).
