Introduction
This section details the necessary environment and conditions for installation
of the PC. For specific instructions on mounting Units and wiring for I/O and
power, refer to
Section 3-3 System Configurations and 4-2 I/O Connections.
Caution Static electricity can cause damage to PC components. Your body can carry an
electrostatic charge, especially when the humidity is low. Before touching the PC
be sure to first touch a grounded metallic object, such as a water pipe, in order to
discharge any static build-up.
5-1 Cooling
There are two points to consider in order to ensure that the PC does not
overheat. The first is the clearance between the Racks, and the second is
installation of a cooling fan.
Clearance Between
Racks
The Racks need to have sufficient room between each other to allow for I/O
wiring, and additional room to ensure that the I/O wiring does not hamper
cooling. However, the Racks must be mounted so that the length of the con-
necting cable does not exceed 2 m, and the total length of the Connecting
Cables between all Racks does not exceed 12 m. For details about cable
lengths, refer to
Appendix C Standard Models. As a general rule, about 70 to
120 mm should be left between any two Racks.
Cooling Fan
A cooling fan is not always necessary, but may be needed in some installa-
tions. Try to avoid mounting the PC in a warm area, or over a source of heat.
A cooling fan is needed if the ambient temperature may become higher than
that specified (refer to
Appendix B Specifications). If the PC is mounted in an
enclosure install a cooling fan, as shown in the following diagram, to maintain
the ambient temperature within specifications.

5-2 Mounting Requirements
The PC consists of from one to nine Racks. Each Rack must be mounted
vertically, that is with the printing on the front panels oriented as it would nor-
mally read. The Racks should be mounted one above the other with the CPU
Rack uppermost.
The PC may be directly mounted to any sturdy support meeting the environ-
mental specifications (refer to
Appendix B Specifications).
