CompactLogix 5370 L2 Controllers

Catalog Numbers 1769-L24ER-QB1B, 1769-L24ER-QBFC1B,

1769-L27ERM-QBFC1B

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.

CompactLogix 5370 L2 Controllers • You cannot remove nor install Compact I/O modules while the controller is powered. ATTENTION: CompactLogix 5370 L2 control systems do not support removal and insertion under power (RIUP). Removing a 1769 Compact I/O module or end cap will generate a controller fault and may also result in damage to system components. Install the Secure Digital Card The CompactLogix 5370 L2 controller is shipped from the factory with the 1784-SD1 SD card installed.

The beveled corner should be at the bottom. If you feel resistance when inserting the SD card, pull it out and change the orientation. 4. Gently press the card until it clicks into place. 32254-M 5. Close the SD card door. 32255-M We recommend you close the SD card door during system operation.

CompactLogix 5370 L2 Controllers Mount the System Mount a CompactLogix 5370 L2 control system on a DIN rail or a panel. WARNING: When used in a Class I, Division 2, hazardous location, this equipment must be mounted in a suitable enclosure with proper wiring method that complies with the governing electrical codes. Available DIN Rails ATTENTION: This product is grounded through the DIN rail to chassis ground. Use zinc-plated yellow-chromate steel DIN rail to assure proper grounding.

CompactLogix 5370 L2 Controllers 7 Mount the Controller on a Panel Use two M4 or #8 panhead screws to mount the controller. Mounting screws are required on every module. Use this procedure to use the assembled modules as a template for drilling holes in the panel. IMPORTANT Due to module mounting hole tolerance, it is important to follow these procedures. 1. On a clean work surface, assemble no more than three modules. 2.

CompactLogix 5370 L2 Controllers 6. Slide the 1769-ECR end cap onto the right side of the controller. The covering covers the exposed interconnections on the right side of the controller. ATTENTION: Failure to use a protective covering could result in equipment damage or injury from electric shock. 32258-M 7. Push the end cap locking mechanism to the right to lock it onto the controller.

CompactLogix 5370 L2 Controllers 11 Consider these points before completing the steps in this section: • An external power supply must reside in the same enclosure as the CompactLogix 5370 L2 controller. If the external power supply and controller are located in separate enclosures, an electrical arc can occur when power is applied. • Not all Class 2 or SELV-listed power supplies are certified for use in all applications, for example, use in both nonhazardous and hazardous environments.
