Compact 16-point 24V dc Sink/Source High-speed Input Module

Module Installation

Compact 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

(1)
Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that occasionally a
temporary conductivity caused by condensation shall be expected.
(2)
Over Voltage Category II is the load level section of the electrical distribution system. At this level transient voltages are
controlled and do not exceed the impulse voltage capability of the product's insulation.
(3)
Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC) designations.

(IEC 60664-1).
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 before removing or inserting this module.
When you remove or insert 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
Electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create
electrical resistance.
