checked for ground integrity to verify that it will handle up to 12A draw and that appropriate branch circuit
protection is in place.

Loading Your Laptops into the Cart
1. Open a Door by pulling the T-handle out from the recessed area. Turn it clockwise 90 degrees and open.
2. Locate the external control switch near the bottom of the unit on the outside. Push the switch to the middle “OFF” position. When in the middle position, power is cut off from both internal and external receptacles. To eliminate any arcing, the switch should be in the off position when devices are being plugged in or removed from the storage bays
and prior to plugging the storage cart into a wall receptacle.
3. Load one laptop into each storage bay. Make sure the power switch is in the middle “OFF” position and then plug them
into the 120 V receptacle in each bay. Repeat the loading on other side of the cart if necessary.
To Charge Your Laptops
1. Locate the external control switch near the bottom of the unit. Move the switch to the middle “OFF” position.
2. Plug in the 12’ power cord for the cart into a suitable receptacle.
3. Push the switch into the down “INSIDE” to direct power inside the enclosure and charge the laptops. External outlets
will not receive power when the switch is in the down position.
To Use the Outside Electrical Receptacles
The storage cart has two 120 V convenience outlets located on the outside of the unit. The maximum electrical output for
the combined external receptacles is 12 A.
1. Locate the external control switch near the bottom of the unit. Move the switch to the middle “OFF” position.
2. Plug in the 12’ power cord for the cart into a suitable receptacle. Plug in your other hardware such as printers and overhead projectors to use the Cart as a lecture station.

Overload Protection (30 Unit Model)
Charging 30 laptop computers at one time combined with the power demands of existing laptop battery technology can
overload a typical 15 amp circuit. Anthro’s 30 Unit Laptop Storage Cart is equipped with a built-in timing device that automatically switches the AC power supply from one side of the Cart to the other.
How It Works:
When the Cart’s external control switch is set to internal power (to charge the laptops), the timer module will provide power
to the Primary Panel (the side of the cart with the power cord) for the amount of time indicated on the Timer Adjustment
(shown right). When that time expires, the cart will provide power to the Secondary Panel (the other side of the cart) until
the time expires. The cart will continue to alternate sides until the external control switch is changed or the cart is unplugged. Every time power is turned off and then restored to the cart, power goes to the Primary Panel first. An indicator
light on the Control Module (located on the bottom shelf inside the cart) indicates which side of the cart is being charged.
The timer is factory-set on a 25-minute cycle. Laptops and equipment with fully depleted batteries will require more than
one cycle to fully charge.
When the cart's external control switch is set to external power, the cart provides power to the two external receptacles
located above the power cord.
Changing the fuse:
In some instances, the fuse will need to be replaced. Check with Customer Care if you believe that your fuse needs to be
replaced. Use an ABC15 (250V, 15A) fuse.
The fuse is located on the side of the timer, next to the power receptacle. Using a flat-head screwdriver, push the fuse in and
turn counter-clockwise until it stops. The fuse will release and pop up in the housing. Remove the fuse and discard. Insert
the new fuse. Use the screwdriver to push the fuse into the housing, and turn clockwise until it stops. The front of the fuse
should be flush with the housing.
Adjusting The Timer:
Use a flat head screwdriver no wider than 1/8” to make this adjustment.
The 25 minute cycle should be optimum for most applications and we don’t recommend adjustment. If adjustment is required, it can be done by a qualified maintenance person following these provided instructions. The timer range is from 15
to 120 minutes.
• Using a flat head screwdriver, gently turn the timer dial
counterclockwise until it stops at position 0.
• Adjust the dial clockwise to the desired setting.
Position 1 provides approximately 25-35 minute cycles.
• The timer key to the left of the dial indicates the cycle
length for each setting.

To Hook Up Your Cart to a Local Area Network
The Storage Cart comes equipped with a data port pass through located near the top and bottom of the unit. The data ports are for network use only. The network receptacles allow the connection of a local area network (LAN) to the base of the Storage Cart and the connection of a wireless networking hub near the top of the Storage Cart.

unlocked position. Push the green tabs on the directional casters to the down position.
2. Make sure the T-handle on the door is recessed so it does not stick out or catch on door frames and corners.
3. When you reach your desired location, push all the tabs on the Casters to the down locked position.

2. Recess the T-Handle.
3. Insert one of the Keys and turn 180 degrees counter clockwise.
4. Repeat for other Door if necesary.

Trouble Shooting Questions
• How do I know if my computers will draw
more than the allowed current?
Our testing indicated it won’t but you can contact
the computer manufacturer to learn the draw of your
computers or have a licensed electrician measure the
current draw if you have concerns.
• The unit sparks when I plug it into the
wall. Is it defective?
No. Make sure the control switch is in the off
position prior to plugging it in.
• The 30 unit Cart appears to have room
for 32 computers. Can I add two more
No. The LTSC30 has 32 shelves but only 30 power
receptacles. The bottom shelves can be used for
storage, but not for charging.
• What are the data ports used for?
If you use a wireless network hub you can set the hub
on the top of the Cart and connect your local area
network (LAN) cable to the RJ45 jack at the bottom
of the cart and connect the wireless hub to the port
located at the top of the cart.
• Someone tried to break into the cart and
damaged a door. Can it be replaced?
• When I plug in the Cart it trips the circuit
breaker. What is wrong?
The Cart is designed to run on a 15 amp circuit. If you have
other equipment or appliances plugged into the same circuit
you may be overloading it. Have a qualified electrician check
the circuit to make sure there is adequate power available.
• My Cart was damaged during shipment. What
should I do?
Please contact Customer Care.
• I have a 30-unit cart; how do I know which side
is being charged?
Check the indicator lights to see where the power is being
directed. For silver control boxes, amber indicator lights are
located on the outsie of each control panel. For black control
boxes, indicator lights are located on the side of the control
• I have a 30-unit cart; how do I know if both
sides of the cart are working correctly?
Watch the indicator lights to see if they light up during a
charging cycle.
• How do I find the cart’s serial number?

the power cord is on the right. Open the door(s). The serial
number label is located on the base shelf in front of you.
