Prerequisites for Replacing Components and Cables

De-Energize the System

 DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
  • Disconnect all power from all equipment including connected devices prior to removing any covers or doors, or installing or removing any accessories, hardware, cables, or wires except under the specific conditions specified in the appropriate hardware guide for this equipment.
  • Always use a properly rated voltage sensing device to confirm the power is off where and when indicated.
  • Replace and secure all covers, accessories, hardware, cables, and wires and confirm that a proper ground connection exists before applying power to the unit.
  • Use only the specified voltage when operating this equipment and any associated products.
Failure to follow these instructions will result in death or serious injury.

How to de-energize the system:

Step

Action

1

Set main switch to OFF position, or otherwise disconnect all power to the system.

2

Prevent main switch from being switched back on.

3

In the case of any drives, servos or other equipment with high capacity capacitors, wait at least 15 minutes after removing power (switching off) to allow the DC bus capacitors to discharge. For other important hazard information, see the user guide of your drive(s).

Other Prerequisites

 DANGER
ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
  • Operate electrical components only with a connected protective ground (earth) cable.
  • After the installation, verify the secure connection of the protective ground (earth) cable to all electrical devices to ensure that connection complies with the connection diagram.
  • Before enabling the device, safely cover the live components to prevent contact.
  • Do not touch the electrical connection points of the components when the module is energized.
  • Provide protection against indirect contact.
  • Connect and disconnect cables and terminals only after you have verified that the power has been removed from the system.
Failure to follow these instructions will result in death or serious injury.

With exception of batteries, there are no other user-serviceable parts within the controllers. Either replace the component or contact your Schneider Electric service representative.

 WARNING
UNINTENDED EQUIPMENT OPERATION
  • Only use software and hardware components approved by Schneider Electric for use with this equipment.
  • Do not attempt to service this equipment outside of authorized Schneider Electric service centers.
