6.2 Mounting
6.2.1 Attaching the power supply unit
The basic CPU module requires the CX2100-0014 or CX2100-0914 power supply unit for the power supply.
Plug the power supply unit into the high-pole connection on the right on the basic CPU module.
None of other power supply units of the CX2000 family are suitable for the CX20x2 Embedded PC.
Proceed as follows:
1. Use the CX2100-0014 or CX2100-0914 power supply unit.
2. Plug the power supply unit into the basic CPU module on the right.
ð Next you can install the bar clips.
6.2.2 Installing the bar clips
Usually, the connection between the modules is strong enough. However, the basic CPU module and the
attached modules may be subjected to shocks, vibrations or other impacts. The modules can be securely
connected to one another with the aid of bar clips.
Install the bar clips as follows:
1. Attach the bar clips at the top and bottom between the cooling fins.
2. Push the bar clips between the cooling fins of your devices, as shown in the image below.
ð
The bar clips have been installed successfully, if they don't protrude and are level with the cooling fins of
your modules.
Once all modules are latched, the devices can be installed on the mounting rail.
