Each Rack must be mounted vertically, that is with the printing on the front pan-
els oriented as it would normally be read. The Racks should be mounted one
above the other with the CPU Rack uppermost as shown below.
The C200HX/HG/HE is approved by Underwriters Laboratories under the condi-
tion that, "The device must be mounted vertically for ventilation purposes."
Connect the CPU Rack to the first Expansion I/O Rack with an I/O Connecting
Cable and then connect each Expansion I/O Rack in order, again using I/O Con-
necting Cables. Each I/O Connecting Cable can be up to 10 m long, but the sum
total of all cables between the CPU Rack and Expansion I/O Racks must be 12 m
or less.
Firmly connect the I/O Connecting Cables to the connectors on the Backplanes
and tighten the connector screws. An I/O bus error will occur stopping PC opera-
tion if any of the I/O Connecting Cables is disconnected. Be sure to connect
these Cables carefully and securely.
This connector is
not used.
Cover is with a cap.
I/O Connecting
Cable
A hole of 53 mm is diameter is required to pass the connectors on the I/O Con-
necting Cables through. This hole can be reduced to 33 mm by removing the
hood from the connector, but be sure to reassemble the connector properly and
securely, and secure it with the connector screws.
The pull strength of the Cables is 5 kg. Do not allow more than 5 kg of force to be
applied to the Cables.
Note 1. The sum of the length of all I/O Connecting Cables in one PC must be 12 m
or less.
2. Be careful to connect the Cables in the correct locations.
3. Always secure the I/O connection cables with the connector screws.
