Prevent Electrostatic Discharge
Electrostatic discharge can damage integrated circuits or semiconductors
if you touch bus connector pins. Follow these guidelines when you handle
the module:
• Touch a grounded object to discharge static potential.
• Wear an approved wrist-strap grounding device.
• Do not touch the bus connector or connector pins.
• Do not touch circuit components inside the module.
• If available, use a static-safe work station.
• When not in use, keep the module in its static-shield box.
Remove Power
Remove power before removing or installing this module. When you
remove or install a module with power applied, an electrical arc may occur.
An electrical arc can cause personal injury or property damage by:
• sending an erroneous signal to your system’s field devices, causing
unintended machine motion
• causing an explosion in a hazardous environment
• causing permanent damage to the module’s circuitry
Electrical arcing causes excessive wear to contacts on both the module
and its mating connector. Worn contacts may create electrical resistance.

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.
Minimum Spacing
Maintain spacing from enclosure
walls, wireways, adjacent
equipment, etc. Allow 50.8 mm
(2 in.) of space on all sides for
adequate ventilation, as shown:
.
1762 expansion I/O may be mounted horizontally only.

DIN Rail Mounting
The module can be mounted using the following DIN rails: 35 x 7.5 mm
(EN 50 022 - 35 x 7.5) or 35 x 15 mm (EN 50 022 - 35 x 15).
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.
During panel or DIN rail mounting of all devices, be sure that all debris
(metal chips, wire strands, etc.) is kept from falling into the module.
Debris that falls into the module could cause damage when power is
applied to the module.
