BMECXM Module Installation
Original instructions
About us
Introduction
In a M580 architecture, you can mount the BMECXM module on a local rack or a remote drop.
The BMECXM module will only power up on a BMEXBP•••• Ethernet backplane.
NOTE: The minimum firmware version for the backplane is V1.0.
For more information on backplane, refer to Modicon X80 Racks and Power Supplies, Hardware, Reference Manual.
Selecting a Backplane
On the BMEXBP•••• backplanes, the BMECXM module can be mounted in any open slot, except the following restrictions:
In addition to the above restrictions on BMEXBP•••• backplanes, some open slots are not allowed for the BMECXM module when mounted on: BMEXBP1002 backplane: slots 2 and 8 are not allowed. BMEXBP1200 backplane: slots 2, 8, 10, and 11 are not allowed.
Grounding Considerations
The BMECXM module is equipped with ground connection contacts at the rear for grounding purposes. These contacts connect the grounding bus of the module to the grounding bus of the rack.
To ground the rack, refer to the chapter Grounding the Rack and Power Supply Module.
Installing the Module on the Rack
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.
To mount the module on the backplane, follow these steps:
Step
Action
1
Turn off the power supply to the rack.
2
Remove the protective cover from the module interface on the rack.
3 
a.
Insert the locating pins on the bottom of the module into the corresponding slots in th rack. 
b.
Use the locating pins as a hinge and pivot the module until it is flush with the rack. (The twin connector on the back of the module inserts the connectors on the rack).
4
Tighten the retaining screw to hold the module in place on the rack:
NOTE: The tightening torque is 0.4...1.5 N•m (0.30...1.10 lbf-ft).
5
Connect the CANopen cable to the CANopen connector of the BMECXM module.
NOTE: For details on CANopen network, refer to CANopen Hardware Setup Manual.
A bad module connection can lead to an unexpected behavior of the system.
WARNING
UNINTENDED EQUIPMENT OPERATION
  • Tighten the retaining screw of the module.
  • Tighten the retaining screws of the SUB-D 9 CANopen connector.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
