7 Applying Power Correctly
7.1 Connecting to electrical outlet
It is highly recommended using a power surge to protect your gear against random power spike damage. This product is provided with a power
supply that
automatically adjusts to input voltages between 100 to 240 Vac . A U.S. and Canadian 125V or 250V power supply cord is provided
with this product. If you are using a 250V power cord, you would need to connect that to a PDU (power distribution unit). You can buy the PDU
on any online electronic stores. OSS does not sell the PDU.
7.2 Connect Power Cord(s)
Connect the supplied power cord to the back of the power supply. Ensure that the system’s power supply unit is fully secured before
connecting the power cord. You should have either the 125v or the 250v power cord. If you only have the 125V power cord and you require the
250V please contact our Sales Team (
sales@onestopsystems.com ) to place an order.
