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.

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.

Figure 4-1. Handle installation.

Step 2. Place the handle so that the holes in the brackets are aligned with the threaded holes in the side panels.

Figure 4-2. Detail A: Handle assembly.

Step 3. Using the included Allen wrench, tighten four of the Allen-head screws into the threaded holes.

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.

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.

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 4-6. 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 4-9. 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.

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.

Step 7. Hold the brick and cords in place by strapping them down using a zip tie or a hook-and-loop tie.

Figure 4-11. Strap the brick and cord in place using a zip tie or hook-and-loop tie (not included).

Step 8. Install the assembled divider into the cart using the following steps.

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.

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.
