Preface Overview Using this Quick Start This quick start is designed to help you quickly install and connect a basic PLC-3 family programmable controller system. Use this guide if you are knowledgeable about PLC-3 family products but may not have used one or more of the products for a period of time. The information we provide is geared to “jog your memory.” What You Need to Do For more information...
P–2 Overview step 4 a b step 5 Install and Connect I/O Install and wire I/O modules (page 5 1) Connect I/O to scanner (page 5 2) Configure and connect a programming terminal (page 6 1) System Components used in this Quick Start Publication 1775 10.
Overview If You Need Help ... A B P–3 If you need additional assistance in installing or connecting your PLC-3 family programmable controller system, start with the troubleshooting section in the appendix of this quick start. If you still experience difficulty, call 1-800-9NEWLIT to order one of the publications suggested below or contact your Allen-Bradley service representative. Publication title: Publication number: PLC 3 Programmable Controllers Installation and Operation Manual 1775 6.7.
Step 1 Configure and Ground I/O and Processor Chassis Configure I/O Chassis a Set the backplane switches.
1–2 Configure and Ground I/O and Processor Chassis Configure Processor Chassis Set the backplane switches located near the upper left hand corner of the chassis backplane.
Step 2 Install Power Supply a Install 1775 P3 Power Supply into the PLC 3/10 (or single chassis PLC 3) Install the dc power cable. PLC 3/10 chassis Feed the dc power cable under the module guides along the backplane. CF2 backplane CF1 Squeeze the side tabs of the plugs as you connect them to the backplane.
2–2 Install Power Supply c Set the voltage switch for the proper range. 115V ac operation 230V ac operation Selector Switch Selector Switch 230V 230V 115V 115V Terminal Strip L1 L2/N GND N.C. COM.

Install Power Supply 2–3 Install 1775 P1 Power Supply into the PLC 3 a Connect the 1775 CAP chassis power cable to the processor chassis. b Optionally, connect the I/O chassis to the power supply using an I/O power cable. We do not recommend this connection for backup system configurations. Power Cable c Make AC power connections.

Step 3 Install Processor, Memory, and Scanner Modules Connect Front Panel Cable and Install Processor Install the processor in the first slot on the left of the chassis for the best heat dissipation. You must install the processor in the chassis numbered 0 if you are using expansion chassis. Install Memory Module(s) (for PLC 3 processor only) a Remove power to the processor chassis.
3–2 Install Processor, Memory, and Scanner Modules Install I/O Scanner Module(s) ! a ATTENTION: Do not change the thumbwheel setting on a scanner while power is on or equipment damage may result. Set each thumbwheel switch to a unique number between 1 and 15. You must have a scanner with the thumbwheel set for 1. If you are installing a multiple chassis PLC 3 system, the scanner module whose thumbwheel you set to 1 must be in the chassis with the front panel.
Step 4 Install, Wire, and Connect I/O Install and Wire I/O Modules For more information... Specific wiring information for each type of I/O module is contained in the product data publication for that specific module. Therefore, refer to the appropriate product data publication when you follow these steps. a Open each module locking bar and insert each I/O module into the slot keyed for it. After you install each module group, secure the modules in place with the module locking bar.
