Simple installation
• To install the CMSS-ONL-2504:
–Mate the connector with CMSS 786M sensor, using thread lock
(Loctite 243 recommended)
–Connect the blue wire to J1-1 (input +) of CMON 2504
–Connect the green wire toJ1-2 (input –) of CMON 2504
–Connect the red wire to IMx channel terminal A [ + ]
–Connect the black wire to IMx channel terminal B [ – ]
–Connect the cable shield to IMx chassis ground bar
• Mount the CMSS 786M sensor per installation instructions
• Connect the CMON 2504 per installation instructions
Terminal A or Brefers to IMx-S
Terminal +or –refers to IMx-W
The cable screen is connected to the body of the sensor and is
usually grounded by the sensor. Note that where the sensor is glued
into position, there may not be an electrical connection and the cable
screen may need to be connected to the earth strip below the DIN
rail.
