Connect ac Power
A standard IEC 320 power cord provides power to the computer. The power supply
input accepts 120/240V ac. The power supply is autoswitching.
Retainer Clip
ATTENTION
Select the power source carefully before connecting your computer.
The power cord must be connected to a terminal block and earth ground.
Failure to follow this warning could result in severe electrical shock.
Installing the computers in a panel, enclosure or rack that is already
connected to Earth ground will satisfy this requirement. Otherwise,
connect your computer to Earth ground using a 1.31 mm
2
(16 AWG) or
larger external wire.
The ground wire should have green insulation with a yellow stripe for easy
identification.
The power source selected must have its own disconnect. Do not connect
the computer to a supply that is connected to the main electrical
disconnect.
To prevent problems resulting from power surges or unexpected power
failure, you should protect the outlet with its own fuses or circuit breakers,
as well as an Uninterruptible Power Supply (UPS) system.
Always shut down the operating system prior to removing power to
minimize performance degradation and operating system failures.
1200P Only:
You may need to remove the ac retainer
clip prior to installing the unit into a
panel cut-out. Attach the clip after
installing the unit.
