Mounting Considerations

Introduction

Observe the following guidelines when you mount the 140CRA31908 module.

Grounding Considerations

DANGER

ELECTRICAL SHOCK HAZARD

Switch off the power supply at both ends of the PAC connection, and lock out and tag out both the power sources.
In case lock out and tag out are not available, ensure that the power sources cannot be inadvertently switched on.
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: For more information, refer to the ground connections topic.

Installation

You can apply power to the Quantum X80 remote drop after the 140CRA31908 module is inserted:

Successful installation:
- Initialization is finished.
- Interconnections to other modules are validated (remote drop adapter module only).
Unsuccessful installation:
- Initialization does not finish.
- Interconnections to other modules are not validated (remote adapter modules only).

You can see the status of the installation on the LED display.

NOTE: These guidelines pertain to the installation of a single 140CRA31908 module, not the entire network. For network power up guidelines, refer to the Modicon M580 Standalone, System Planning Guide for Frequently Used Architectures.

adapter

An adapter is the target of real-time I/O data connection requests from scanners. It cannot send or receive real-time I/O data unless it is configured to do so by a scanner, and it does not store or originate the data communications parameters necessary to establish the connection. An adapter accepts explicit message requests (connected and unconnected) from other devices.
