OUTPUT CONNECTIONS
The output (welding) cables are connected to the output terminals marked “+” and
relief for the cables is provided by routing them through the rectangular holes in the base before connecting them to the output terminals. Lift the output terminal cover to access the output terminals. Lower the cover after making the connections. See Figure A.6.
