IMPORTANT: Remember the following:
• Connect the white end of the CJC sensor to the even-numbered
terminal. Connect the orange end of the CJC sensor to the
odd-numbered terminals.
For CJC 0:
– White end - Connected to terminal number 2
– Orange end - Connected to terminal number 1
For CJC 1:
– White end - Connected to terminal number 36
– Orange end - Connected to terminal number 35
• CJC sensors do not come with the module. You must order the
sensors, product catalog number 1756-CJC, separately.
• If separate power sources are used, do not exceed the specific
isolation voltage as listed in the specifications.
