Receiving and Unpacking the VelociRack
Inspect and report any damage before receiving the shipment.
The VelociRack is shipped with a shock sensor (Figure 1). If the sensor indicates rough handling, check if
the shock sensor was activated on the receiving documents. Inspect the rack for any visual damage and
note those items on the receiving documents. Thoroughly evaluate and report concealed damage to the
shipment within five days of the delivery date.
Figure 1: Shock Sensor Warning.
Unpack the VelociRack by carefully removing the outer packaging carton and corners. Avoid damaging
the rack when removing packaging.
Use extra caution when removing the VelociRack from the pallet. Also, be sure you have
enough service personnel. Do not attempt to move racks by yourself.
1. Unpack the ramps.
 After removing the wrapping from the cabinet, you should have two ramps (Figure 2). A
small hardware back wrapped to the outside of one ramp will contain four wood screws.

Figure 2. Rack Pallet Detail.
2. Locate the proper end of the pallet.
 One end of the pallet will be cut to accommodate the ramps. Pilot holes drilled into this
end of the pallet will be used to attach the ramps with the supplied wood screws (Figure
3).
Figure 3. Pilot Holes Used to Attach the Ramps.
3. Secure ramps to pallet.
4. Insert the wood screws into the pilot holes and tighten them (Figure 3).

Figure 4: Ramps Attached to the Pallet.
5. With several people, carefully and slowly roll the VelociRack down the ramps and off the pallet.
Be careful when moving racks before installation. Sudden stops and starts, excessive
force, obstructed routes, and uneven floor surfaces may cause the rack to topple
over.
6. Move the VelociRack to the installation location.

Installing the VelociRack
This section provides information for installing the VelociRack.
Leveling the VelociRack
After the VelociRack has been moved to the installation location, the leveling feet can be lowered for
additional stability.
Leveling feet are installed at the factory. They are easily accessible in the front and rear of the rack’s
frame. Figure 5 illustrates how to adjust the leveling feet from beneath the VelociRack using a 3/4-inch
open-end wrench. Leveling feet can also be adjusted from inside the rack using a 5/16 socket.
Figure 5: Leveling-Feet Adjustment Detail.
Connecting the VelociRack Power
The VelociRack power connection is made using one of three forms of data center power as recorded on
a submittal drawing in power diagram.
Verify each data center power distribution for the rack has a NEMA 5-15R outlet run to
dedicated 120 Vac 15-amp branch circuit located in the overhead busway or below the floor
within reach of the PDU 10-foot power cord.
NOTE
PDU A is located at the rear of the rack’s enclosure, at bottom left, and PDU B is located at
the rear of the rack’s enclosure, at bottom right. If necessary, relocate the PDU higher in the
rack’s enclosure to reach an overhead outlet. The PDU power cords in the horizontal wire
management are at the bottom rear of the rack.
Siemens Industry, Inc.


Standard A/B power: Plug PDU A into the outlet for service A and PDU B into the outlet for
service B.

Optional emergency power: Plug PDU A into the outlet for building service and PDU B into the
outlet for the emergency service.

Optional no backup power: Plug PDU A into the outlet for building service and leave PDU B
unplugged with the cord remaining in wire management.
VelociRack Factory-Installed Power Distribution Wiring
