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
Over Voltage Category II
(2)
(IEC 60664-1).
Prevent Electrostatic Discharge
(1)
) and to circuits not exceeding
(3)
ATTENTION
!
Remove Power
ATTENTION
!
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.
(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.

System Assembly
The module can be attached to the controller or an adjacent I/O module before or
after mounting. For mounting instructions, see
Rail Mounting on page 8. To work with a system that is already mounted, see
Replacing a Single Module within a System on page 8.
The following procedure shows you how to assemble the Compact I/O system.

1. Disconnect power.
2. Check that the bus lever of the module to be installed is in the unlocked
(fully right) position.
3. Use the upper and lower tongue-and-groove slots (1) to secure the modules
together (or to a controller).
4. Move the module back along the tongue-and-groove slots until the bus
connectors (2) line up with each other.
5. Push the bus lever back slightly to clear the positioning tab (3). Use your
fingers or a small screw driver.
6. To allow communication between the controller and module, move the bus
lever fully to the left (4) until it clicks. Ensure it is locked firmly in place.
ATTENTION
When attaching I/O modules, it is very important that the
bus connectors are securely locked together to ensure
proper electrical connection.
