Appendix C - External DC Power Supply Enclosure Installation (Optional)
THESE INSTRUCTIONS ARE APPLICABLE FOR EXTERNAL DC POWER SUPPLY INSTALLATIONS ONLY.
ENSURE PRIMARY POWER IS SHUT OFF AT THE BREAKER.
• One power supply is required per lane. Each power supply enclosure can house up to three power supplies.
The power supplies are pre-installed at Alvarado prior to shipping. Make sure to locate all required components,
and verify the correct number of power supplies are present prior to beginning installation.
• It is assumed that conduit has been run to the master/center cabinet for each lane for low-voltage 24VDC power
wiring. Refer to Conduit Requirements section on Pages 9 and 33 for more information.
• Due to the various mounting methods and surfaces available for mounting the enclosure, mounting hardware
and detailed mounting instructions are not provided.
• Wire gauge recommendations for 30, 50, and 100 ft. runs are provided on Page 36. If your installation requires
runs beyond 100 ft, ensure wire gauge is appropriate and in compliance with local electrical codes.
• The location of the power supply enclosure must adhere to the Environmental Requirements section found on
Page 9. Controlled environments such as an electronics closet are ideal.
• See Page 38 for power supply enclosure dimensions.
• It is strongly recommended that a licensed electrician perform this procedure in accordance with applicable
local electrical codes.
• Throughout this document, the power supply enclosure is shown with three power supplies installed. The
instructions are the same for single and dual power supply installations.
