Unit 10 (CH 181 to 200)
•
When the terminals are added, please connect continuously them without disconnected terminals. If there
is a disconnected terminal, subsequent terminals are not recognized.
•
When the combination of the standard terminal and Withstand high-voltage high-precision terminal is
used, the withstand voltage specication of standard terminal is applied.
•
When the terminal of the GL800 or the GL820 is used, or the combination of the GL800 and the GL820 is
used, the temperature measurement accuracy may not satisfy the specication.
•
The Withstand high-voltage high-precision terminal is not available for the GL800 and GL820.
When direct-connecting with 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.
