Environment and Enclosure
ATTENTION
This equipment is intended for use in a Pollution Degree 2 industrial
environment, in overvoltage Category II applications (as defined in IEC
publication 60664-1), at altitudes up to 2000 meters (6562 ft) without derating.
This equipment is considered Group 1, Class A industrial equipment according
to IEC/CISPR Publication 11. Without appropriate precautions, there may be
potential difficulties ensuring electromagnetic compatibility in other
environments due to conducted as well as radiated disturbance.
This equipment is supplied as open-type equipment. 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, V2, V1, V0 (or equivalent) if
non-metallic. The interior of the enclosure must be accessible only by the use
of a tool. Subsequent sections of this publication may contain additional
information regarding specific enclosure type ratings that are required to
comply with certain product safety certifications.
In addition to this publication, see:
• Industrial Automation Wiring and Grounding Guidelines, Allen-Bradley
publication 1770-4.1
• NEMA Standards publication 250 and IEC publication 60529, as
applicable, for explanations of the degrees of protection provided by
different types of enclosure
, for additional installation requirements.

Prevent Electrostatic Discharge
ATTENTION
ATTENTION
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.
• Store the equipment in appropriate static-safe packaging when not in
use.
POINT I/O is grounded through the DIN rail to chassis ground. Use zinc plated,
yellow-chromate steel DIN rail to be sure of proper grounding. The use of other
DIN rail materials, such as aluminum and 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 (7.87 in.) and
use end-anchors appropriately.
To comply with the CE Low Voltage Directive (LVD), all connected I/O must be
powered from a source compliant with the following:
Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV).

About the Module
The 1734-8CFG module is a 24V DC I/O module with 8 self-configuring
points. Each of the I/O points can be a DC input or output. The module
supports removal and insertion under power, auto-address, and auto-baud in
compliance with the POINTBus backplane.
Before You Begin
See the figures to familiarize yourself with major parts of the module, noting
that the wiring base assembly is one of the following:
• 1734-TB or 1734-TBS POINT I/O two-piece terminal base, which
includes the 1734-RTB removable terminal block and 1734-MB
mounting base
• 1734-TOP or 1734-TOPS POINT I/O one-piece terminal base
The 1734-8CFG module is not compatible with 1734-TB3, 1734-TB3S,
1734-TOP3, and 1734-TOP3S terminal bases.

Install the Mounting Base
Follow these steps to install the mounting base on the DIN rail.
1. Position the mounting base vertically above the installed units, for
example, adapter, power supply, or existing module.
2. Slide the mounting base down so that the interlocking side pieces
engage the adjacent module or adapter.

4. To remove the mounting base from the DIN rail, remove the module,
and use a small bladed screwdriver to rotate the base locking screw to
a vertical position. This releases the locking mechanism. Then lift
straight up to remove.

The module can be installed before, or after base installation. Make sure 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.

Install the Removable Terminal Block
Read this for information if a removable terminal block (RTB) is supplied
with your wiring base assembly, noting that 1734-TOP and 1734-TOPS bases
do not have an RTB.
To insert the RTB, proceed as follows. Note that if you pull up on the RTB
handle to remove the RTB, you can remove and replace the mounting base as
necessary without removing any of the wiring.
1. Insert the end opposite the handle into the base unit, noting that 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 into
place.
3. If an I/O module is installed, snap the RTB handle into place on the
module.
