Introduction
5.1 Wiring Suggestions
This section describes the cautions that you need to exercise when performing wiring for the power
supply and input and output devices.
5.1.1 Grounding Requirements
1) Power and module grounding
Set a grounding point on the backplate near the power plate and paint it for protection. Use a thick
cable shorter than 30 cm to connect the
terminal of the power module to the
terminal for
grounding.
Install the AM600 series module on the conductive backplate according to the following figure and paint
the bolts that connect the guide rail under the AM600 modules to the conductive backplate to ensure
reliable connection.

2) Shielded cable grounding
Use shielded cables for high-speed I/O
,
analog I/O
,
fieldbuses
,
and communication signals.
The grounding point must be close to the module to prevent the cables from being affected by
electromagnetic induction generated by the cables that exist before grounding. Ensure that the contact
area between the shield exposed after some of the sheath of the shielded cable is peeled off and the
conductive backplate is as large as possible to ensure good contact.
