DC Wiring Diagram
For 100-240 VDC rated equipment, an appropriately rated DC circuit breaker must be installed.
•
The specification for HV DC breaker is 5 A, 2P, 300 VDC (min) Circuit breaker, Thermomagnetic or
equivalent type. A recommended option for this circuit breaker is: Model No.
CX2-B0-14-450-22A-13G, Molded Case Circuit Breaker, 2 P, 5 A, 250/500 VDC.
•
Wire gauge sizing is to be selected with appropriate design as per the Electrical code for a 60 W,
1-phase device.
Equipment must be installed according to applicable local wiring codes and standards.
With the power source turned off, refer to figure
and perform the following steps:
For a DC Power Supply in PS1, carry out steps 1 through 2.
1.
Connect the positive wire from the power source to the positive/live (+/L), screw #1, terminal on
the terminal block.
2.
Connect the negative wire from the power source to the neutral/negative (-/N), screw #3, terminal
