Installation Guidelines

Ensure the CPU module is installed inside a sealed control panel to guard against dust, moisture, and particulate contaminants. Always disconnect all power sources before mounting the module onto the CJ-series backplane. Grounding must be established using a dedicated ground wire connected to a functional ground terminal with a resistance of less than 100 Ohm to prevent electromagnetic interference.
