3-Phase 12.5kW Power System
Indicates highly-dangerous consequences such as fire, serious injury, or death when
failing to comply with the instructions.
Indicates dangerous consequences such as moderate injury or equipment damage when
failing to comply with the instructions.
Introduction
The 12.5kW Power System is a 3-phase, dual-input, 6-slot chassis with 2.5KW Power Supply Units (PSUs)
that provides stable DC output power (12.5VDC / 1000A). This 19-inch power system uses up to 6 highpower, dual-input, hot-swappable PSUs for flexibility in full power or redundant operation. For more
information about the 12.5kW Power Shelf, refer to the Lite-On 12.5kW Power Shelf Datasheet.
The 2.5kW Dual-Input PSUs efficiently supply both main output DC power and standby DC power from
either AC or DC sources. These compact PSUs provide 2.5kW, 12.5V / 200A and support PMBUS 1.2 with
boot loader, LED status indicators, and circuit protection features. For more information about the 2.5kW
PSU, refer to the Lite-On 2.5kW Dual-Input Power Supply Unit Datasheet.
This user guide provides instructions to install the 12.5kW Power System. For instructions on initial startup,
refer to the Lite-On 3-Phase, Dual-Input, 12.5kW Power Supply System Startup Guide.

1. Remove the front panel from the shipping crate.
2. Remove any shipping bolts from the rack that hold the rack to the crate.
3. If necessary, remove any shipping blocks or straps from around the rack.
4. If necessary, raise the leveling feet to their highest position.
5. Secure a ramp to the front of the crate.
6. Using two or more people, carefully roll the rack out of the crate and down the ramp.
7. Inspect the rack to ensure that it was not damaged during shipping.
To unpack items from cardboard shipping boxes:
1. If necessary, remove any shipping straps from around the box.
2. Place the box upright and cut through the tape on the top of the box.
3. Remove the item(s) from the box along with any shipping foam if necessary.
4. Remove the item(s) from any shipping foam or wrapping material.
After all items have been unpacked, verify that you have received all the items as specified by the shipping
paperwork.
Equipment Inspection
After unpacking the equipment, inspect it for damage that might have resulted from shipment. Check for
the items below and contact the shipper in the unlikely event that damage is found.
• Bent connectors, alignment pins, or chassis
• Any cracks or chips on plastic components
• Unusual scratches or marks
• Dents in sheet metal or panels
• Corrosion or evidence of water or chemical damage
• Indications that the device was dropped
• Loose parts inside the equipment
Power Shelf and Rack Preparations
These instructions assume that the rack has been moved into place and is installed properly. If necessary,
refer to the User Guide of the rack for more information about installing it.
The Power Shelf slides into a 19-inch rack and is supported in the rack by shelf support brackets. If the
Shelf Support Brackets are not already installed in the rack, follow instructions “Shelf Support Brackets
Installation” on page 5 to install the brackets.
Before the Power Shelf is installed into the rack, Linking Bus Bars are loosely installed on the rear of the
Power Shelf; they are tightened after the Power Shelf is mounted into the rack. Follow instructions in
section “19-Inch to 21-Inch OCP Rack Adapter” if installing the Power Shelf into a 21-inch OCP rack.

Power Supply Unit Installation and Removal
The Power Shelf supports up to six (6) hot-swappable Power Supply Units (PSUs). A PSU can be plugged
into any slot in the Power Shelf and they are keyed so they cannot be inserted incorrectly.
As shown below, PSUs are held in place with a spring latch.
Spring Latch
To install a Power Supply Unit:
1. Slide a PSU into an empty slot of the Power Shelf until it clicks into place.
2. Slide the remaining PSUs into the empty slots in the Power Shelf until they click into place.
To remove a Power Supply Unit:
• Lift the spring latch on the front of a PSU, pull the handle, and slide the PSU out from the Power
Shelf.
Power Shelf Controller Installation (Optional)
While optional, the Power Shelf Controller (PSC) is necessary for system communication to the power
system created by the power shelf along with a battery shelf. The PSC is an integral part of a complete DC
UPS system with communication capabilities. It provides communication to the Lite-On Site Monitoring
Controller (SMC) or other monitoring software for information and/or event-based responses.
On the front of the power shelf is a slot for the PSC. As shown below, a Power Shelf Controller is held in
place with a spring latch.
