Installing the ControlLogix
1756sc-CTR8 Module
Use this guide to install and wire your ControlLogix 1756sc-CTR8 module. The
1756sc-CTR8 Module mounts to an Allen-Bradley ControlLogix 1756 Controller
chassis. The module uses a Removable Terminal Block (RTB) to connect all
field-side wiring.
Before you install your module, you should have already:
•
Installed and grounded a 1756 chassis and power supply.
•
Ordered and received an RTB and its components for your application.
WARNING
Electrostatic discharge can damage integrated circuits or
semiconductors if you touch backplane connector pins.
To prevent damage, follow these guidelines when you handle the module:
•
Touch a grounded object to discharge static potential.
•
Wear an approved wrist-strap grounding device.
•
Do not touch the backplane connector or connector pins.
•
Do not touch circuit components inside the module.
•
If available, use a static-safe workstation.
•
When not in use, keep the module in its static-shield box.
WARNING
Hazard of electrical arcing when removing or inserting the module
while power is applied to the rack.
This module is designed so you can remove and insert it under backplane
power and field-side power. When you remove or insert a module while
field-side power is applied, you may cause an electrical arc. An electrical
arc can cause personal injury or property damage because it may:
•
Send an erroneous signal to your system’s field devices, causing
unintended machine motion or loss of process control.
•
Cause an explosion in a hazardous environment.
•
Repeated electrical arcing also causes excessive wear to contacts on
both the module and its mating connector. Worn contacts may create
electrical resistance.
