Connecting power

WARNING
Risk of electric shock!
Improper grounding of electrical devices involves a risk of
serious injury or death by electric shock.
Always use 3-wire power cables.
Make sure the ground wire is correctly connected to
the ground of the building's electrical installations.
WARNING
Fire hazard from the use of power cables that do not
meet the minimum requirements!
Use only power cables that fulfill or exceed the
specified minimum requirements.
NOTICE
Surge suppressors limit the amplitude of potentially
damaging power line transients caused by electrical
machinery or lightning, and protect the product from
most power line transients that can corrupt system
memory or damage circuits.
Always connect the unit to power through a high-
quality surge suppressor.
Use the supplied power cable to connect the power
connector to a 3-wire grounded power outlet. For
information about the location of the power connector
on the rear panel, see "Rear panel", page 17.
