Connect Power; Functional Ground Screw - Allen-Bradley 6177R-MM User Manual

Connect Power

Functional Ground Screw

A grounded, 3-prong IEC60320-C13 power cord provides power to the
computer. The power supply input accepts 100...240V AC and is autoranging.
ATTENTION: When you connect power to the computer for the first time, the
following actions occur:
• The default UEFI setting automatically starts the computer after it is plugged
into a power source.
• You must read and accept an End User Setup procedure for computers with a
Windows operating system (requires an external display).
Do not disconnect power from the system until after the Windows Setup
procedure is completed. If power is disconnected during this procedure, it
can result in a corrupted system image.
Operate the computer in an industrial or control room environment, which
uses some form of power isolation from the public low-voltage mains.
ATTENTION: Supply the computer circuit with its own disconnect. Use an
uninterruptible power source (UPS) to help protect against unexpected
power failure or power surges.
Always shut down the Windows operating system before you disconnect power
to the computer to minimize performance degradation and operating system
failures.
Follow these steps to connect the computer to an AC power source.
1. Connect the power cord to the AC power input. See
starting on page 13
model.
2. Connect the AC power cord to a power source.
SHOCK HAZARD: Connect the AC power cord to a power source with
an earth ground. Failure to follow this warning can result in electrical
shock.
3. Apply 100...240V AC power to the computer.
The pre-installed functional ground screw is not required for safety or
regulatory compliance. If a supplemental ground is desired, use the functional
ground screw on the rear panel of the 750R and 1450R computers. See pages
14 and 15 for where the functional ground screw is on each computer model.
If you use the functional ground screw, connect the computer to earth ground

by using a 1.5 mm (16 AWG) or larger external wire. Use a ground wire with
an insulation color that is approved by the local inspection authority.
