(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.
