1-6 What is the 1756-SYNCH module?
Preventing Electrostatic
Discharge This module is sensitive to electrostatic discharge.
Removal and Insertion
Under Power These modules are designed to be installed or removed while chassis power is
applied.
Repeated electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create electrical
resistance that can affect module operation.
Chapter Summary and
What’s Next In this chapter, you read about the ControlLogix SynchLink module. For
information about Time Synchronization in the ControlLogix System, see
Chapter 2.
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.
• If available, use a static-safe workstation.
• When not in use, store the equipment in appropriate
static-safe packaging.
WARNING
When you insert or remove the module while backplane
power is on, an electrical arc can occur. This could cause an
explosion in hazardous location installations. Be sure that
power is removed or the area is nonhazardous before
proceeding.
