(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.
