All servicing or repair operations perfor-

med on the AVR should be undertaken by 

personnel trained in the commissioning, 

servicing and maintenance of electrical 

and mechanical components.

 

When the generator is driven at a 

frequency below 28 Hz for more than 30 

seconds with an analogue AVR, its AC 

power supply must be disconnected. 

WARNING

This AVR can be incorporated in a EC-

marked machine.
