John Deere Products & Services Portable Generator DCA70SSJU4i User Manual

3Ø, 600 VAC can be achieved via the auto-transformer 

module. This module provides the necessary electronics 

to convert the 3Ø, 480 VAC inut voltage to a 3Ø, 600 VAC 

output voltage.
The 3Ø, 600 VAC ouput voltage cannot be achieved unless 

the voltage selector switch (Figure 29) is placed in the 3Ø, 

480/277 position.

1.  Loosen the latches on the control box enclosure and 

open the door.

2.  Drill a 1-1/2 inch hole at the bootom control box
