Mounting Precaution for CJ1W-NC413/NC433

Ambient Operating Temperature
26
The ambient operating temperature of the CJ1W-NC413/NC433 PCUs is 0 to
50 ° C. The ambient operation temperature range, however, can be increased
to 0 to 55 ° C if the CJ1W-SP001 CJ-series Space Unit is used under the fol-
lowing conditions.
• A Space Unit is mounted between CJ1W-NC413/NC433 PCUs and any
adjacent Units other than CJ1W-NC413/NC433 PCUs.
• Whenever there are two or more CJ1W-NC413/NC433 PCUs mounted
together on a Rack, a Space Unit is mounted between every two CJ1W-
NC413/NC433 PCUs.
The following example shows how to use the Space Units when three CJ1W-
NC413/NC433 PCUs are mounted to the same Rack.

Power Supply Unit
Note A maximum of 10 Units can be connected in the CPU Rack or any Expansion
Rack, including Space Units. The CPU Unit and CX-Programmer, however,
will not detect the Space Unit as a Unit on the Rack. An error will thus not
occur for any Rack that exceeds the maximum of 10 Units because of the
presence of Space Units. If there are more than 10 Units on a Rack, operating
errors may occur with other Units, such as Special I/O Unit errors. Always be
careful not to have more than 10 Units in any Rack when using Space Units.
