Quantum EIO-Compatible Module Installation Considerations
Original instructions
Introduction
Observe the following guidelines when you install these Quantum and Modicon X80 modules in a Quantum EIO system:
Grounding Considerations
DANGER
ELECTRICAL SHOCK HAZARD
  • Switch off the power supply to the automation controller stations at both ends of the connection before inserting or removing an Ethernet cable.
  • Use suitable insulation equipment when inserting or removing all or part of this equipment.
Failure to follow these instructions will result in death or serious injury.
Use fiber-optic cable to establish a communications link when it is not possible to master potential between distant grounds.
NOTE: Refer to the ground connections information in Electrical installation guide.
Installation
You can apply power to the Quantum EIO controller rack after the 140CRP31200 head module or adapter module is inserted:
You can see the status of the installation on the LED display.
NOTE: Because all modules on the local rack are initialized when power is applied, the 140CRP31200 remote I/O head module can only validate the interconnections with 140NOC78000 and 140NOC78100 head modules after these modules have been initialized. Therefore, the adapter module waits until its queries about the interconnected port information are answered.
NOTE: These guidelines pertain to the installation of a single head module or adapter module, not the entire network. For network power-up guidelines, refer to Quantum EIO, System Planning Guide.
