Prevent Electrostatic Discharge
ATTENTION: 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.
ATTENTION: The ControlLogix system has been agency certified using only the ControlLogix RTBs (catalog numbers 1756-
TBNH and 1756-TBSH). Any application that requires agency certification of the ControlLogix system using other wiring
termination methods may require application specific approval by the certifying agency.

Power Requirements

56
This module receives power from the 1756 chassis power supply and requires 2
sources of power from the backplane:
300mA at 5.1V DC
16mA at 24V DC
Add this current/power value (1.7W) to the requirements of all other modules
in the chassis to prevent overloading the power supply.
