MicroLogix™ 1762-IQ8 DC Input Module Installation 1762 I/O is suitable for use in an industrial environment when installed in accordance with these instructions. Specifically, this equipment is intended for use in clean, dry environments (Pollution degree 2 ) and to circuits not exceeding Over Voltage Category II (IEC 60664-1). -
Page 5: Mounting
MicroLogix™ 1762-IQ8 DC Input Module Mounting ATTENTION: Do not remove protective debris strip until after the module and all other equipment near the module is mounted and wiring is complete. Once wiring is complete and the module is free of debris, carefully remove protective debris strip. Failure to remove strip before operating can cause overheating. - Page 6 Before mounting the module on a DIN rail, close the DIN rail latch. Press the DIN rail mounting area of the module against the DIN rail. The latch will momentarily open and lock into place. Use DIN rail end anchors (Allen-Bradley part number 1492-EA35 or 1492-EAH35) for vibration or shock environments. End Anchor...
