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.
