Replace a DC power supply in a single-supply system
Before you perform a DC power supply unit (PSU) replacement, you need to provide these tools and
components:
• 12 AWG copper cable long enough to reach from the platform to the DC power source
• Flat-head or Philips head screwdriver
In the event of a power supply unit (PSU) failure, you can replace a DC PSU in a single-supply system.
Caution: Be sure that you are using the correct wattage power supply when performing a power supply
replacement.
1. Use the touchscreen LCD to halt and power off the system.
Performing a proper shutdown procedure helps maintain system integrity.
2. Be sure that the circuit breaker for the DC mains power source is switched off.
3. Remove the failed DC PSU by squeezing the ejector latch and pulling straight toward you.
Note: After you remove a power supply unit (PSU) from the system, ensure that the replacement PSU
has been unpowered for 30 seconds to ensure that the PSU circuitry is fully discharged before
inserting the replacement PSU into the system.
4. If a connector protective cap is installed on your new PSU, remove it prior to installing the PSU into
your system.
5. Inspect the new PSU, especially the connector area, for any damage that might have occurred during
shipment.
6. Assemble the DC cable by connecting one of the included DC ring terminals to one end of each of
your 12 AWG copper cables.
7. Remove the terminal cover.
8. Use a screwdriver to remove the screws from the DC power terminals.
9. Connect the ring terminal for the positive (+) DC wire (typically red) to the left terminal, and the ring
terminal for the negative (-) DC wire (typically black) to the right terminal.
