The following information describes the installation requirements necessary to

(PC-A984-145, PC-E984-241, PC-E984-245, PC-E984-251, PC-E984-255, AS-
BDAP-210, AS-BDAP-218, AS-BVIC-200, AS-BVIC-205, AS-BVIC-212, AS-BVIC-

AS-BADU-212, AS-BADU-204, and AS-BMOT-201) Compact 984 components.
Use the following requirements for installations complying with the CE marking:
Use Braided Shielded Cable on all power supply, communications, and I/O lines.
Either the Modicon Grounding Bar (Modicon part number 043509693) or a
compatible device may be used. The cable should have at least 80% shield
coverage. If you are using the Grounding Bar, the Outer Diameter of the shield
should be in the range of 0.189 ... 0.240 in (4.8 ... 6.0 mm).
All cable shields must be grounded using the clips on the Grounding Bar.
Alternatively, you can supply an equivalent low impedance RF ground clamp.
CPU/PS ground terminal (Ground) must be left open as shown.
Install braided earth ground from building earth ground to grounding clip (or clips
as required) and to backplane 0 Volt reference.
Use the plastic faceplate supplied with the backplane to cover the front of
modules.
If using a BMOT-201 module, all cables (Motor I/O Cable, Encoder Cable and I/
O Cable) exiting the BMOT-201 module must pass through a large Ferrite Bead
(Steward part number 28 B2400-000).
Note: For information about specific I/O modules, please refer to the A120 Series
I/O Modules User Guide (890 USE 109 00 formerly GM-A984-IOS).
