(4) If the converter needs to be installed in a location where watertight installation is required, make
unused cable ports watertight. (Be careful that the attached blind plate is used for dustproof
purpose and it is not effective for watertight installation.)
(5) The converter has a surge arrestor/protector installed inside. Therefore, do not conduct a withstand
voltage test for the converter. In addition, to check the insulation of the converter, use a voltage of
250VDC or less.
(6) When wiring is completed, be sure to install the protection cover of the terminal block.
5.1 Installation Cables
Use the kind of cables shown in Table 5.1 to connect to the converter.

The number of insulated conductors the cable contains differs
depending on the specification of the output signal cable.
Use a shielded cable of overall diameter 0.433 to 0.512 inch
(11 to 13mm) with nominal cross-sectional area of 1.25mm
