KIT-AUX COOLER 4518378 - Caterpillar

Single Units
Each unit should be connected to a common ground.In a three-phase, four-wire system, the neutral wire should be grounded according to local wiring codes. Be sure to check your local wiring codes.Connection Diagrams

The generator lead connections are located in the terminal box on the generator or in the enclosure for the control panel. (1) Terminal Box on the Generator (2) Enclosure for the Control PanelThe generator lead connections are located in the terminal box on the generator or in the enclosure for the control panel.Change the position of the wire terminals in order to modify the connection. The code for the winding is specified on the nameplate.Wiring Code A for Three-Phase Configuration
