3.1.1 Precautions for Installation
For system configuration through Pnet I/F module, carefully make sure of the following items prior to
installation.
1) Check the basic factors necessary for system configuration to select an appropriate communication
module.
2) Select the exclusive Pnet cable to be used for this communication module.
3) Before the communication module is installed, check for any foreign material on the base connector the
module will be installed on and any damage on the connector pin of the module.
4) All the communication modules can be installed on the basic base ~ the expansion base. For the
number of available expansion base by CPU, refer to the following table.

5) For installation of the module, exactly insert the protuberant part at the bottom of the module with the
communication cable disconnected into the base groove and then apply enough strength until its top is
locked up with the locking device of the base. If the lock is not applied, it may cause an error on the
interface with CPU.
