General Information about Wiring

Overview

Use only Schneider Electric approved devices in your application, and especially Schneider Electric pre-fabricated cables wherever and whenever possible.

For further information, refer to Cable Characteristics.

For information on the tightening torques and cable cross-sections, refer to Electrical Connections Overview.

Observe the following points when wiring:

1.Observe the minimum cross-sections of the cables necessary for the load carrying capacity of the equipment being connected.

2.Verify the integrity of cable shields to ensure continuity to ground.

3.Ensure that there is a proper connection to ground for all interconnected equipment.

4.Ensure connection of the motors to the machine ground.

5.Eliminate any ground loops.

6.Do not disconnect cable connections terminals when under power.

7.Ensure that all ground connections have sufficient surface area continuity.

8.Do not interchange motor phases.

9.Do not interchange encoder connections.

10.Do not interchange the EMERGENCY STOP circuits.

Example

If, for example, two parallel conductors are shown as coming from one point, you may not run just one conductor and then branch it off at a later point. If it is wired this way, induction loops (interference emitters and antennas) as well as interfering potential shifts may occur.
