Prevent Electrostatic Discharge

Before You Begin

Consider the following before installing a CompactLogix

5370 L2 controller:

The control system includes a controller, an embedded power supply,
and embedded I/O points.

The embedded power supply is a 24V DC input, isolated power supply.

You must connect an external Class 2 or SELV-approved power supply
to provide 24V DC power to the system.

The controllers have embedded I/O points. You wire the input and
output points via a removable connector.

The controller supports the use of Compact I/O

modules on the local

1769 CompactBus backplane as local expansion modules.

You must terminate the end of the CompactBus via a 1769-ECR right
end cap.

This equipment is sensitive to electrostatic discharge, which can cause internal damage and
affect normal operation. Follow these guidelines when you handle this equipment:

Touch a grounded object to discharge potential static.

Wear an approved grounding wriststrap.

Do not touch connectors or pins on component boards.

Do not touch circuit components inside the equipment.

Use a static-safe workstation, if available.

Store the equipment in appropriate static-safe packaging when not in use.
