This equipment is supplied as open-type equipment for indoor use. It must be
mounted within an enclosure that is suitably designed for those specific
environmental conditions that will be present and appropriately designed to
prevent personal injury resulting from accessibility to live parts. The enclosure
must have suitable flame-retardant properties to prevent or minimize the spread
of flame, complying with a flame spread rating of 5VA or be approved for the
application if nonmetallic. The interior of the enclosure must be accessible only
by the use of a tool. Subsequent sections of this publication may contain more
information regarding specific enclosure type ratings that are required to
comply with certain product safety certifications.
In addition to this publication, see the following:
• Industrial Automation Wiring and Grounding Guidelines, publication
1770-4.1, for more installation requirements.
• NEMA Standard 250 and EN/IEC 60529, as applicable, for explanations of
the degrees of protection provided by enclosures.
ATTENTION: This equipment is sensitive to electrostatic discharge which can
cause internal damage and affect normal operation. Follow these guidelines
when you handle this equipment.
• Touch a grounded object to discharge potential static.
• Wear an approved grounding wriststrap.
• Do not touch connectors or pins on component boards.
• Do not touch circuit components inside the equipment.
• Use a static-safe workstation if available.

Install the Mounting Base
To install the mounting base on the DIN rail (Allen-Bradley® part number 199-DR1;
46277-3; EN50022), proceed as follows.
1. Position the mounting base vertically above the installed units (adapter, power
supply, or existing module).
ATTENTION: This product is grounded through the DIN rail to chassis ground.
Use zinc plated chromate-passivated steel DIN rail to assure proper grounding.
The use of other DIN rail materials (for example, aluminum or plastic) that can
corrode, oxidize, or are poor conductors, can result in improper or intermittent
grounding. Secure DIN rail to mounting surface approximately every 200 mm
(7.8 in.) and use end-anchors appropriately. Be sure to ground the DIN rail
properly. Refer to Industrial Automation Wiring and Grounding Guidelines,
Rockwell Automation publication 1770-4.1, for more information.
WARNING: When used in a Class I, Division 2, hazardous location, this
equipment must be mounted in a suitable enclosure with proper wiring method
that complies with the governing electrical codes.

2. Slide the mounting base down to make the interlocking side pieces engage the
adjacent module or adapter.
3. Press firmly to seat the mounting base on the DIN rail.
The mounting base snaps into place. Be sure that the orange DIN rail locking
screw is in the horizontal position and that it has engaged the DIN rail.
Install the Module
The module can be installed before or after base installation. Make sure that the mounting
base is correctly keyed before installing the module into the mounting base. In addition,
make sure the mounting base locking screw is positioned horizontal referenced to the base.
To install the module, proceed as follows.
1. Use a bladed screwdriver to rotate the keyswitch on the mounting base clockwise
until the number required for the type of module you are installing aligns with
the notch in the base.
2. Verify the DIN rail locking screw is in the horizontal position.
You cannot insert the module if the locking mechanism is unlocked.
ATTENTION: Do not discard the end cap. Use this end cap to cover the exposed
interconnections on the last mounting base on the DIN rail. Failure to do so
could result in equipment damage or injury from electric shock.
WARNING: When you insert or remove the module while backplane power is
on, an electrical arc can occur. This could cause an explosion in hazardous
location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
Repeated electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create electrical
resistance that can affect module operation.

Install the Removable Terminal Block
A Removable Terminal Block (RTB) is supplied with your wiring base assembly. To
remove, pull up on the RTB handle. This allows the mounting base to be removed and
replaced as necessary without removing any of the wiring. To reinsert the Removable
Terminal Block, proceed as follows.
1. Insert the end opposite the handle into the base unit.
This end has a curved section that engages with the wiring base.
2. Rotate the terminal block into the wiring base until it locks itself in place.
3. If an I/O module is installed, snap the RTB handle into place on the module.
WARNING: When you connect or disconnect the Removable Terminal Block
(RTB) with field-side power applied, an electrical arc can occur. This can cause
an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.

Remove a Mounting Base
To remove a mounting base, you must remove any installed module and the module
installed in the base to the right. Remove the removable terminal block, if wired.
1. Unlatch the RTB handle on the I/O module.
2. Pull on the RTB handle to remove the removable terminal block.
3. Press the module lock on the top of the module.
4. Pull on the I/O module to remove from the base.
5. Repeat steps 1, 2, 3, and 4 for the module to the right.
6. Use a small-bladed screwdriver to rotate the orange, base locking screw to a
vertical position.
This releases the locking mechanism.
7. Lift straight up to remove.
WARNING: When you insert or remove the module while backplane power is
on, an electrical arc can occur. This could cause an explosion in hazardous
