Wiring diagram for the circuit breaker
(1) 343-8446 Power Cable (MACHINE POWER TO CIRCUIT BREAKER)
(2) 6T-3642 Circuit Breaker As
(3) "POWER" branch of 343-8444 Power Cable (CIRCUIT BREAKER TO COMPONENT) to the "POWER" branch of the 357-7167 Power Harness As
(4) Unused "POWER" branchNote: The power requirements are 5 amps at 20 to 30 VD. Nominal voltage is 24 V. The power supply is not supplied with the installation group.Two 10 Amp, 125 VAC, or 36 VDC circuit breakers are used in the system.The following components are required to supply power to the system:
343-8446 Power Cable (MACHINE POWER TO CIRCUIT BREAKER)
343-8444 Power Cable (CIRCUIT BREAKER TO COMPONENT)
6T-3642 Circuit Breaker AsNote: A quantity of two is required.
343-8438 Circuit Breaker Mounting GpTwo power cables are supplied with the 438-1654 Machine Wiring Gp. The 343-8446 Power Cable (MACHINE POWER TO CIRCUIT BREAKER) connects the machine power to the circuit breakers. The 343-8444 Power Cable (CIRCUIT BREAKER TO COMPONENT) connects the circuit breakers to the required components to provide power to these components.Three lugs are supplied in two different sizes to attach the 343-8446 Power Cable to the machine power. The different sizes are #8 and #10. Select the appropriate size according to the size of the terminals on the machine power.Perform the following procedure to connect the power cables:
Accidental machine starting can cause injury or death to personnel working on the machine.To avoid accidental machine starting, turn the battery disconnect switch to the OFF position and remove the key. If the machine is not equipped with a battery disconnect switch, disconnect the battery cables from the battery and tape the battery clamps.Place a do not operate tag at the battery disconnect switch location to inform personnel that the machine is being worked on.
Ensure that the machine power is turned off.
Select a lug size from the two available sizes that are supplied with the 343-8446 Power Cable (MACHINE POWER TO CIRCUIT BREAKER). To attach the selected lugs, crimp the selected lugs to each of the following wires on the 343-8446 Power Cable:
"POWER"
"KEY"
"GND"
Connect the "POWER", "KEY", and "GND" leads from the 343-8446 Power Cable to the corresponding terminals for machine power.
Attach the "POWER" lug on the other end of the 343-8446 Power Cable to the terminal on a circuit breaker.
Attach the "KEY" lug on the other end of the 343-8446 Power Cable to the terminal on the second circuit breaker.
Connect the "GND" disconnect terminal on the 343-8446 Power Cable to the "GND" disconnect terminal on the 343-8444 Power Cable (CIRCUIT BREAKER TO COMPONENT).
Attach the "BAT+(101)" lug from the 343-8444 Power Cable to the second terminal of the same circuit breaker from Step 4.
Attach the "KEY+(105)" lug from the 343-8444 Power Cable to the second terminal of the same circuit breaker from Step 5.Installing the Circuit Breakers
Perform the following procedure to install the two 6T-3642 Circuit Breaker As:
Use the 343-8491 Template (CIRCUIT BREAKER) to determine the two locations for mounting the circuit breakers on the circuit breaker panel.Note: Ensure that there
