3 Installing and wiring the hardware14
3.1 What components are required?NoteIf you do not have a motor,you can still implement theexample. In this case, you willobserve the LEDs on the digital outputs of the CPU 312C.In order to control the conveyor belt, you will need the components shown: Power supply for the control components CPU 312C with integrated input and output module Mounting rail for installing the modules Momentary contact switch Motor for driving the conveyor belt (optional) PC with STEP 7 Lite including Service Pack 2 PC Adapter USB for connecting the PC with the CPU 312C15SIMATIC S7-300 Getting Started for First Time UsersGetting Started, 04/2007, 6ZB5310-0NC02-0BA0
3 Installing andwiring the hardware3.2 Installing the componentsIn this section, we show you how to: Install and ground the mounting rail Install the modules on the mounting rail Insert the front panel connectorInstalling and grounding the mounting rail1. Screw the mounting rail to thesubsurface. Use two M6 screwsfor this.2. Connect the mounting rail to theground wire.The prescribed minimum cross-section for the cable to the protective conductoris 10 mm2.Note the following information when installing the mounting rail: Make sure to maintain a clearance of at least 40 mm above and below themounting rail. This is needed to satisfy the requirements for thermal conditions(heat dissipation and ventilation of the module) and to facilitate the installation(mounting and removing, wiring). If the subsurface is a grounded metal plate or a grounded device panel, makesure you have a low resistance connection between the mounting rail and thesubsurface. This produces a uniform reference potential.16SIMATIC S7-300 Getting Started for First Time UsersGetting Started, 04/2007, 6ZB5310-0NC02-0BA0
Installing modules on the mounting rail1. Install the power supply, tightening the screws hand-tight.2. Install the CPU 312C.3. Insert the front panel connector into the CPU 312C until it engages.The front panel connector still protrudes from the module in this wiring position, and is not yet connected to the module. This position makes it easier foryou to complete the wiring.17SIMATIC S7-300 Getting Started for First Time UsersGetting Started, 04/2007, 6ZB5310-0NC02-0BA0
3 Installing andwiring the hardware3.3 Wiring the componentsWarningDangerous electrical voltages!Death or serious bodily injuryand damage to machineryand equipment can occur ifyou do not observe the following safety precautions.Before starting work, disconnect the system and thedevice from the power supply.Wire the system components to the CPU 312C. This enables the CPU 312C todetect and evaluate the state of the components with the help of the control program. The momentary-contact switches are signal transmitters. You connect the signal transmitters to the input terminals of the CPU 312C. The input terminalsare labeled with “DI”. The motor is the signal receiver. You connect the signal receiver to the outputterminals of the CPU 312C. The output terminals are labeled with “DO”.The entire control loop is connected to the power supply via the CPU 312C.Preparing the cables1. Cut the cables to the desiredlength.2. Remove the insulation and pressthe ferrules onto the ends of thecable.18SIMATIC S7-300 Getting Started for First Time UsersGetting Started, 04/2007, 6ZB5310-0NC02-0BA0

3. Set the main switch of the power supply to “ON”.The DC24V LED on the power supply will light up. All LEDs on the CPU 312Cwill light up briefly, and the DC5V LED and the STOP LED will remain lit.29SIMATIC S7-300 Getting Started for First Time UsersGetting Started, 04/2007, 6ZB5310-0NC02-0BA0
3 Installing andwiring the hardwareTesting the connectionsNow, test your wiring to verify that it is functioning properly.NoteTo make the example easierto follow, we will use coloredmomentary contact switches.You can implement the example with commercially available momentary contactswitches of any color.For this purpose, take turns pressing the momentary contact switches andobserve the LEDs on the inputs of the CPU. Whenever an input is activated, thecorresponding LEDs always light up. Press the green momentary contact switch for “Motor ON”. The LED of input0.0 (terminal 2) will light up. Press the red momentary contact switch for “Motor OFF”. The LED of input0.1 (terminal 3) will light up. Press the right momentary contact switch for “Clockwise rotation”. The LED ofinput 0.2 (terminal 4) will light up. Press the left momentary contact switch for “Counterclockwise rotation”. TheLED of input 0.3 (terminal 5) will light up.You have installed, wired, and tested all components. Next, you will create thecontrol structure in STEP 7 Lite and download the configuration to theCPU 312C.30SIMATIC S7-300 Getting Started for First Time UsersGetting Started, 04/2007, 6ZB5310-0NC02-0BA0
