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.
Operate the device only from the type
of external power source indicated on
the electrical ratings label.
To help avoid damaging your device,
be sure the voltage selection switch (if
provided) on the power supply is set
to match the power available at your
location.
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 a power
cable for your device or for any AC
-powered option intended for your device, purchase a power cable that is
approved for use in your country and
is suitable for use with your device.
The power cable must be rated for the
device and for the voltage and current
marked on the device's electrical rat ings label. The voltage and current rating of the cable should be greater
than the ratings marked on the device.
To help prevent an electrical shock,
plug the device 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 3wire cable with properly grounded
plugs.
Observe extension cable and power
strip ratings. Ensure that the total ampere rating of all products plugged
into the extension cable or power strip
does not exceed 80 percent of the am pere ratings limit for the extension ca ble or power strip.
To help protect your device from sud den, transient increases and decreases in electrical power, use a
surge suppressor, line conditioner, or
uninterruptible power supply (UPS).
Do not modify power cables or plugs.
Consult a licensed electrician or your
power company for site modi cations.
Always follow your local/national wiring rules.
When connecting or disconnecting
power to hot-pluggable power sup plies, if o
ered with your device, ob-
serve the following guidelines.
Install the power supply before con necting 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 de vice by unplugging all power cables
from the power supplies.
