Installing the CPU and Coprocessor

Introduction

You can install the BME•58•040S CPU and BMEP58CPROS3 coprocessor only in either a BMEXBP••00 or BMEXBP••02 Ethernet rack.

Installation Precautions

An M580 CPU is powered by the rack bus. Confirm that the rack power supply is turned off before installing the CPU.

DANGER

HAZARD OF ELECTRIC SHOCK

Remove all power sources before installing the CPU.

Failure to follow these instructions will result in death or serious injury.

Remove the protective cover from the rack slot connectors before plugging the module in the rack.

WARNING

UNEXPECTED EQUIPMENT OPERATION

Check that the CPU does not contain an unsupported SD memory card before powering up the CPU.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

NOTE:

Check that the memory card slot door is closed after a memory card is inserted in the CPU.
Refer to %SW97 to check the status of the SD card.

Installing the CPU and Copro in the Rack

Install the CPU and Copro in the rack at the following slot locations:

CPU: slots 00 and 01.
Copro: slots 02 and 03

Follow these steps to install a CPU and Copro in a rack:

Step	Action
1	Verify that the power supply is turned off.
2	Verify the following: If an SD memory card is used, it is supported by the CPU. The connectors’ protective covers are removed. The CPU is placed on the slots marked 00 and 01.
3	Position the locating pins situated at the bottom rear of the module in the corresponding slots on the rack.
4	Swivel the module towards the top of the rack so that the module sits flush with the back of the rack. The module is now set in position.
5	Tighten the 2 screws on top of the CPU to maintain the module in place on the rack. tightening torque: 0.4...1.5 N•m (0.30...1.10 lbf-ft).
6	To install the Copro module, place it in slots 02 and 03 and follow steps 3, 4, and 5, above.

Grounding

Follow all local and national safety codes and standards.

DANGER

HAZARD OF ELECTRIC SHOCK

If you cannot prove that the end of a shielded cable is connected to the local ground, the cable must be considered as dangerous and personal protective equipment (PPE) must be worn.

Failure to follow these instructions will result in death or serious injury.

For information on grounding the CPU and coprocessor, refer to the topic Grounding Considerations in the Modicon M580 Hardware Reference Manual.
