CPU
The CPU is in one of the expansion/control slots to the left of the output
connectors and has connectors (ports) for attaching external control
devices. The CPU also has a system status light, a network use light
(Ethernet Status indicator), and ports for linking to other enclosures.
Expansion/Control Slots
Each enclosure provides three expansion/control slots. One contains the
CPU board and two are for future boards that will increase functionality
and add new features to your system. One is located above the CPU and
one is below it.
Power Supply
The power supply is on the top left corner of the rear of the enclosure.
The power supply holds the power switch, power connector, and fuse
drawer. The power supply fan vent is to the right of the power supply
unit.
The 8Y-XL input voltage range is AC 100-240V single phase. The
power supply will accept all major, international power sources (see page
B-1).
The fuse drawer is just above the power switch and contains two 2 AMP
Time Delay (5mm x 20mm) fuses.
Press the “0” side of the power switch to turn power off; press the “1”
side to turn it on.
We recommend surge protectors and/or an AC line conditioner.
Serial Number
The serial number for the system is located on a plate between the input
and output connectors.
