Installing the 140 NOP 850 00 Module
(Original Document)
About us
Introduction
Use these instructions to mount a 140 NOP 850 00 module onto a Quantum local rack.
Grounding Considerations
Do not apply power to a Quantum rack until connections are made at both ends of the Ethernet cable. For example, connect the cable to both the 140 NOP 850 00 and another device or ConneXium dual-ring switch DRS before you turn on the power.
Refer to the Quantum EIO System Planning Guide for details on dual-ring switches (DRSs).
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.
Mounting a Module
Step
Action
1
Hold the module at an angle and mount it on the 2 hooks near the top of the backplane. The figure shows the correct way to hold the module:
2
Swing the module down so the connector engages the backplane connector.
3
Use a Phillips-head screw driver to tighten the screw at the bottom of the module from 2 to 4 in-lbs or from .22 through .45 N•m of torque.
Replacing a Module
You can replace a 140 NOP 850 00 module at any time using another 140 NOP 850 00 module. The replacement module obtains its operating parameters over the backplane connection from the CPU. The transfer occurs immediately at the next cycle to the device.
The operating parameters that the CPU sends to a replacement module do not include any parameter values that were edited in the original module using explicit messaging SET commands.
