www.dell.com | support.dell.com
• Use the product only with Dell products or other Dell-approved 
equipment. 
• Allow the product to cool before removing covers or touching internal 
components.
• Use the correct external power source. Operate the product only from 
the type of power source indicated on the electrical ratings label. If you 
are not sure of the type of power source required, consult your Dell 
service provider or local power company.
• Use only approved power cable(s). If you have not been provided with 
a power cable for your server, storage system, or appliance, or for any 
AC-powered option intended for your system, purchase a power cable 
that is approved for use in your country. The power cable must be 
rated for the product and for the voltage and current marked on the 
product’s electrical ratings label. The voltage and current rating of the 
cable should be greater than the ratings marked on the product. 
• To help prevent electric shock, plug the system/components and 
peripheral power cables into properly grounded electrical outlets. 
These cables are equipped with three-prong plugs to help ensure 
proper grounding. Do not use adapter plugs or remove the grounding 
prong from a cable. If you must use an extension cable, use a three-
wire cable with properly grounded plugs.
• Observe extension cable and power strip ratings. Make sure that the 
total ampere rating of all products plugged into the extension cable or 
power strip does not exceed 80 percent of the extension cable or power 
strip ampere ratings limit.
• To help protect your system/components from sudden, transient 
increases and decreases in electrical power, use a surge suppressor, line 
conditioner, or uninterruptible power supply (UPS).
• Position system cables and power cables carefully; route system cables 
and the power cable and plug so that they cannot be stepped on or 
tripped over. Be sure that nothing rests on your system components’ 
cables or power cable.
• Do not modify power cables or plugs. Consult a licensed electrician or 
your power company for site modifications. Always follow your 
local/national wiring rules.
