13 DIAGRAM FOR TEST WITHOUT GENERATOR

Below is the diagram for regulator connection on the bench where the equipment operation may be verified before connection to
the generator.
Material required:
1 - Small screwdriver;
1 - Incandescent lamp;
1 - Lamp socket;
1 - Bipolar breaker (5A recommended);
1 - Extension cable;
1 - Plug 110V or 220V*.
* For voltage 110V, select refeeding jumper class "A";
* For voltage 220V, select refeeding jumper class "C";
NOTE
1. After performance of such steps as per the procedure the equipment must be sent for evaluation by
GRAMEYER technical support.
1º. Mount circuit as per diagram below;
2º. With small screwdriver, turn trimpots Vad and U/F counter-clockwise until the end of stroke;
