Space requirements for installation
Observe the following guidelines when installing your module:
• The CP 243-1 is designed to naturally dissipate heat by means of convection.
Therefore, leave a space of at least 25 mm both above and below the device to
ensure adequate heat dissipation. Long operating times at maximum ambient
temperature and maximum load shorten the operating life of the electronic
components.
• When installed horizontally, the CP 243-1 must always be installed immediately
to the right of the CPU.
• When installed vertically, the maximum allowable ambient temperature is lower
by 10 °C. The CP 243-1 must be arranged above the CPU. If you use a vertical
standard DIN rail, you should use the standard DIN rail stopper to prevent the
module from shifting.
• The depth required for installation is 75 mm.
Note
Erect the devices in such a manner that there is sufficient space for the wiring of
the inputs and outputs and for the communications cable connections.
