Module mounting
The following shows the procedure to mount the module. In this procedure, mount the target module on the base unit. This
procedure is common among all the modules.
In direct change, control is immediately started after the module is mounted. Thus, after mounting a terminal block and
connectors to the module, check that the system does not malfunction and mount the module.
