Page 4: Handling The Module
DeviceNet RS-232 Interface Module Handling the Module ATTENTION: This RS-232 module uses CMOS technology, which is highly sensitive to electrostatic discharge (ESD). ESD may be present whenever you are handling the module. Take these precautions to guard against electrostatic damage: Avoid touching the interface connector pins on the RS-232 module. - Page 5 1770-5.6, DeviceNet RS-232 Interface Module Installation Instructions If you ordered catalog no. 1770-KFDG, your order also includes a global 9V ac power supply adapter (90 – 260V ac). If you are missing any of these pieces, contact your Allen-Bradley sales representative.
