Chapter 3: Precautions
3.0 Electrical Precautions
• The power switch must be in the “OFF” position before plugging the NBC into a
wall receptacle.
• The NBC must ONLY be connected to a 120-volt AC 15- or 20-amp power supply.
• The NBC must only be used by adults or with adult supervision.
• Always store the power cord around the cord wraps when transporting the NBC.
• Never pull the NBC by the power cord.
• Do not plug the NBC in if the switch, receptacle(s), or power cord have been
damaged. All electrical components on this product must be repaired by a qualified
electrician.
• Do not use an extension cord in conjunction with the NBC.
• Do not use liquids in or around the NBC environment.
• Inadequate repair can create significant hazards to users and is not covered by
warranty.
• For your safety, it is recommended that a qualified electrician test the circuit you
will be plugging the NBC into. The circuit should be checked for ground integrity
and appropriate branch circuit protection.
• The NBC ground prong must be present for safe operation. If the plug is damaged
or if the ground prong has been removed, it should be replaced by a qualified
electrician.
• The use of the NBC including plugging or unplugging netbooks, plugging or
unplugging the NBC, operating the control switch, and engaging or releasing the
directional and locked casters must be done with adult supervision.
3.1 Other Precautions
• The NBC can be very heavy when fully loaded with netbooks and should be moved
about by persons physically able to do so.
• The NBC should only be used for the storage, transport, and charging of netbooks,
tablet PCs, ultra mobile PCs, and other similar devices.
• Misuse, incorrect operation, or inadequate repair of the NBC will void the warranty.

Chapter 4: Configuration and Setup
4.0 Configuration and Setup
Remove and discard all packaging materials and then lock the lockable casters.
Open and inspect the NBC to verify all doors, locks, and casters are working properly.
Do not plug the NBC into an outlet until all configurations and setup are complete.
4.1 Installing the Handle
It is possible to install the handle/cord wrap on either side of the NBC. Black Box
recommends that you mount the handle on the side of the cart with the locking
swivel casters.
NOTE: The casters swivel on one side of the NBC and are fixed on the other. Consider
maneuverability options before installing the handle.
Step 1. Locate the side of the cart with the locking swivel casters.

Chapter 4: Configuration and Setup
4.2 Fastening Power Bricks to the Dividers
Attach power bricks to the dividers to create separate slots for the netbooks.
Remove a divider to install a netbook power brick on the divider.
Step 1. Lay the divider flat on the work surface. Lay a netbook and a power brick on
top of the divider, with the computer end of the power wire toward the top of the
divider. Plug the power brick into the netbook. Lay the wire across the two holes at
the top of the divider. Make sure that there is some slack between the front hole and
the plug.
Make sure there
is slack at these
two points
Netbook
Cord slack
Note this point
Power Brick
Align the back of the netbook
with the back of the divider
Figure 4-3. How to thread the electrical cable through the dividers.
Step 2. Note the point where the power wire meets the rear hole in the divider.
Measure back 6" toward the power brick and fold the wire in half to create a loop in
the center of the wire. This loop will be used in Step 3, page 11. Unplug the power
wire from the netbook and remove the netbook from the divider.
Figure 4-4. Loop the electrical cord and push it through the circular hole at the top
rear of the divider.

NBC20S-R2
Chapter 4: Configuration and Setup
Step 3. Insert the loop created in Step 2 through the rear small hole at the top of the
divider (Figure 4-4). Then, place the plug end of the wire through the loop (Figure
4-5). Make sure that the loop is on the side of the divider (not on top of it—see
Figure 4-6). This will ensure that the divider will slide back into the cart. Then, tighten
the loop down to the divider, tightening the knot.
Figure 4-5. Insert the plug end of the wire through the loop.
Keep the loop here
Power brick end
Figure 4-6. Make sure the loop is on the side of the divider, not on top of it.
Step 4. Run the wire along the top of the divider and repeat the process of creating
a loop in the power cord. Place this loop through the small hole at the front of the
divider (Figure 4-7). Now place the plug end of the wire through the loop (Figure
4-8). Pull the end of the cable, tightening the loop (Figure 4-9).
Figure 4-7. Create a loop from the power cable and feed it through the hole at the
top front of the divider.

Figure 4-9. Pull the cable taught to secure the loop.
Step 5. Wrap the remaining length of power cord around the power brick (see Figure
4-11, page 13.
Step 6. Wrap the plug wire around the brick. Leave at least 7" of extra cable if the
divider will be inserted into the bottom shelf, or at least 21" of extra cable if the
divider will be inserted into the top shelf.
Lower shelf: 7"
Upper shelf: 21"
Figure 4-10. Wrap the remaining electrical cable around the power brick.
Leave 7" of extra cable if the divider will be inserted into the bottom shelf, or
at least 21" of extra cable if the divider will be inserted into the top shelf.

NOTE: For proper installation, make certain that all power bricks are installed on the
same side of every divider.

4.3 Inserting Dividers Into the Cart
Step 1. Beginning with the top row, insert a divider into the cart.
NOTE: This version of the cart provides additional divider slots to allow the user to
customize the size of the storage slots.
Figure 4-13. Begin to insert dividers into the top row of the cart.
Step 2. Then from the back of the cart, insert the power brick plugs hanging from
the dividers on the left side of the cart into the power receptacles located on the
bottom left of the cart. Repeat with the power brick plugs on the right side of the
cart into the power receptacles located on the bottom right of the cart.
Figure 4-14. Netbook Cart dividers with attached power bricks.
Step 3. Plug the power cord from the bottom left receptacles into one of the timer’s
receptacles and the power cord from the bottom right receptacles into the timer’s
other receptacle.

Figure 4-15. Electrical schematic for the back of the Netbook Cart.
Note the location of the timer.
In the back of the NBC, insert the power cord from the 10 or 16 electrical outlet unit
into the LEFT outlet on the timer and plug the other electrical outlet unit into the
RIGHT outlet on the timer. Push the timer tabs (located at the edges of the timer dial)
inward towards the center of the dial. This will turn one side of the outlets on while
turning the other off.
4.4 Routing the Power Cords at the Back of the Netbook Cart
Step 1. Plug the netbook outlet strips into the timer unit
Step 2. Feed the cord from the timer through the grommet hole on the side nearest
the handle and wrap the cord around the handle itself or around the cord wrap
below the handle.
Step 3. Plug the timer into a wall outlet.
NOTE: The outlet strips are only to be used for charging netbook computers.

5.4 Timer Instructions
Before using your timer:
• For your safety, we recommend that a qualified electrician test the circuit you will
plug the cart into. The circuit should be checked for ground integrity and
appropriate branch circuit protection.
• The cart’s ground prong must be present for safe operation. If the plug is damaged
or if the ground prong has been removed, it should be replaced by a qualified
electrician.
• Using the cart, including plugging it in or unplugging it, plugging in or unplugging
the laptop or other electrical equipment, or operating the control switch must be
done with adult supervision.
The timer comes preset from the factory to alternate power between the power
strips at 15 minute intervals. To change time settings, first unplug the timer from the
wall. Using a flat blade screwdriver, turn the timer dial to a new number:
0 = 15 min. 1 = 30 min. 2 = 45 min. 3 = 60 min.
4 = 75 min. 5 = 90 min. 6 = 105 min. 7 = 120 min.

Both power strips cannot charge simultaneously.
By plugging the cart power cord into an approved outlet and flipping the red switch
located on the left side panel of the cart, the cart will begin charging.
