Do not push any objects into the openings of the system. Doing so can cause fire or electric shock by
●
shorting out interior components.
Use the product only with approved equipment.
●
Allow the product to cool before removing covers or touching internal components.
●
Operate the product only from the type of external power source indicated on the electrical ratings
●
label. If unsure of the type of power source required, consult your service provider or local power
company.
To help avoid damaging the system, be sure the voltage selection switch (if provided) on the power
●
supply is set to match the power available where the switch is located:
115 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern countries
●
such as South Korea and Taiwan
100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan
●
230 V/50 Hz in most of Europe, the Middle East, and the Far East
●
Also, be sure that attached devices are electrically rated to operate with the power available in your
●
location.
Use only approved power cable(s). If you have not been provided with a power cable for your
●
system 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 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 using an
extension cable is necessary, use a 3-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 ampere
ratings limit for the extension cable or power strip.
To help protect the system 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 cables so that they cannot be stepped on or
●
tripped over. Be sure that nothing rests on any cables.
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.
When connecting or disconnecting power to hot-pluggable power supplies, if offered with your
●
system, observe the following guidelines:
Install the power supply before connecting the power cable to the power supply.
●
Unplug the power cable before removing the power supply.
●
If the system has multiple sources of power, disconnect power from the system by unplugging all
●
power cables from the power supplies.
Move products with care; ensure that all casters and/or stabilizers are firmly connected to the
●
system. Avoid sudden stops and uneven surfaces.
