5.6 Cautionary Notes on Replacing Converter
5.6.1Replacing the LF230 Converter
The following precautions must be taken to replace the conventional type LF230 with LF232.
Installation
•Since the hole diameter and pitch for mounting fitting, and the dimensions of the LF232 converter main unit are the same as those of the LF230 converter, it is possible to replace the converter without changing the mounting panel, installation space, etc.
•The operation switches of the LF232 are infrared switches. If direct sunlight hits the display and the operation section or if there is something nearby that easily reflects light, this kind of light becomes disturbance light and the switch operation may not work correctly. Be careful about the installation location and angle, or take measures such as providing a sunshade or shield plate so that disturbance light does not hit the operation section directly.
Wiring
•The positions of the LF232 cable ports are the same as those of the LF230.
•The specifications of the cable ports differ as shown in the table below.

Note: The blind plate is not a waterproof type. If it is necessary to install the converter where waterproof structure is needed, take waterproof measures for unused cable ports such as using sealing plugs sold on the market.
•Since the terminal block specification of the LF232 is M4 screws, the same as that of the LF230, it is possible to connect the cables without changing the cable terminals.
