TUBE AS 5098639 - Caterpillar

Schematic is for reference only.The application will determine the PTs and CTs that will be needed. That is, for example, if the generator output is wired for 240 V, the PT output will be 240 V. The black and white wire of the input must be used for the one to one ratio.The following is another example. The output of the PT will be 240 V if the following configuration is used:
The generator is wired for 600 V output
The generator is wired to the black and red input wires of the PTNote: The PT uses a 2.5 to one ratio for this configuration.Refer to Illustration 30.
Illustration 30 g03171820
Schematic is for reference only. The voltage rating for the installation will determine which connections are correct. For example, installations that use 240 V will use the black and white wires. For installations that use 380 V, the black and green wires are to be used.

Direct Rack Connections - Without Accessory DC Harness
Note: There are two options for direct rack connections. One option is that the customer DOES NOT order a DC harness that is installed from the panel to the generator. The other option is the DOES order a DC harness that is installed from the panel to the generator.If a DC harness is not ordered, then make the following connections. The connections are made directly to the EM-C4, 40 pin connector. The connector is located on the bottom of the EMCP control panel. The connector is the location for the 0-200ma signal from the governor output.
Install the DR+ wire to pin 11.
Install the DR- wire to pin 31.

(101) ECMP panelRefer to Special Instruction, REHS0848, "3500 Direct Fuel Control Modification" for related information.If the CDVR is used, the CAN 1 termination resistor must be removed if there is a CAN termination resistor at the CDVR. Refer to Illustration 27 for the location of the CAN 1 termination resistor inside the panel.Direct Rack Connections - With Accessory DC Harness
If a DC accessory harness is ordered, make the following connections. The connections are made directly to terminal blocks that are located inside of the generator terminal box.
Connect the internal DC harness 361-7002 to the DC terminal strip 361-6974 as follows:
Connect F702-YL to terminal PWM1+.
Connect J842-GN to terminal PWM1-.
Connect the 0-200 mA actuator output of the governor to the terminal strip 361-6974 as follows:
Connect the 0-200 mA+ to terminal PWM+.
Connect the 0-200 mA- to terminal PWM-.Programmable Discrete Input Connections
