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 12A.
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.
3. Push the external control switch to the up “EXTERNAL” position. You will feel a positive engagement of the switch indicating
power to the external receptacles. In this position the internal receptacles are disabled and no charging to stored computers
will occur.
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.

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.
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.
Circuit Breaker:
There are two circuit breakers on the LTSC30. One is on the timer module and the other is on the power
inlet module located underneath the cart. If there is no power to internal and external outlets, check to see if
the circuit breaker on the power inlet module is tripped. If there is power to the external outlets but not to the
internal outlets, check to see if the circuit breaker located on the timer module is tripped.
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.

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 computers?
No. The LTSC30 has 32 shelves but only 30
power receptacles. The bottom shelves can be
used for storage, but not for charging.
•Someone tried to break into the
cart and damaged a door. Can it be
replaced?
Yes, please contact Customer Care.
•My computers didn’t charge
overnight. What is wrong?
Make sure the Cart is plugged in. Make sure
the control switch is pushed to the lower
position marked “Internal Power On”.
•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. Indicator lights are located on the
outside left and right side panels.
•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?
Position the cart so you’re standing in front of the doors
and 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.
