Other Manuals Agency Appr ovals Technical Assistance Preface viii Simatic TI505 RTD Input Module User Manual Many integrated circuit (IC) devices are susceptible to damage by the discharge of static electricity . Follow the suggestions listed below to reduce the probability of damage to these devices when you handle a controller , a base controller , or any of the I/O modules. Both the module and the person who handles the module should be at the same ground potential. T o accomplish this, fulfill the following conditions. • T ransport the module in an anti-static container or anti-static material. • Ensure that the work area has a conductive pad with a lead that connects it to a common ground. • Ground yourself. Make contact with the conductive pad or wear a grounded wrist strap. If there is any visible damage to the module, contact your vendor for replacement.
