Unit 10 (CH 181 to 200)
• When the terminals are added, please connect continuously them without disconnecting terminals.
If there is a disconnected terminal, subsequent terminals are not recognized.
• When the combination of the Standard 20CH screw terminal and Withstand high-voltage high-precision terminal is used,
the withstand voltage specification of the standard terminal is applied.
• When using a Standard 30CH screwless terminal in combination, terminals connected across 200CH will not be
recognized.
Example: When 190CH is implemented with eight Standard 20CH screwless terminals and one Standard 30CH screwless
terminal, even if an additional Standard 20CH screwless terminal is installed, the total will be 210CH, so the additional
terminal will not be recognized.
CAUTION
When direct-connecting with an extension terminal connection cable
1. Connect between the extension terminal bases with the extension terminal connection cable.
* Insert the extension terminal connection cable until the cable is securely locked.
* Connect in accordance with the connector shape.
