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 60664-1), at altitudes up to 2000 m (6562 ft) without derating.
This equipment is not intended for use in residential environments and may not
provide adequate protection to radio communication services in such

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 additional
information regarding specific enclosure type ratings that are required to
comply with certain product safety certifications.

ATTENTION: Personnel responsible for the application of safety-related
programmable electronic systems (PES) shall be aware of the safety
requirements in the application of the system and shall be trained in using the
system.
ATTENTION: FLEX I/O systems are grounded through the DIN rail to chassis
ground. Use zinc plated yellow-chromate 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.
ATTENTION: Do not remove or replace a Terminal Base unit while power is
applied. Interruption of the backplane can result in unintentional operation or
machine motion.
ATTENTION: For Class I Division 2 applications, use only Class I Division 2
listed or recognized accessories and modules approved for use within the 1794
platform.
ATTENTION: If this equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be impaired.
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.
WARNING: If you connect or disconnect wiring while the field-side 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.

ATTENTION: During mounting of all devices, be sure that all debris (such as
metal chips or wire strands) is kept from falling into the module. Debris that
falls into the module could cause damage on powerup.
To install the module on a 1794 terminal base, refer to the figure and complete the
following.
1. Rotate the keyswitch (2) on the terminal base (3) clockwise to position 3 as
required for this type of module.
2. Make sure the flexbus connector (7) is pushed all the way to the left to connect
with the neighboring terminal base or adapter.
ATTENTION: You cannot install the module unless the connector is fully
extended.

3. Make sure the pins on the bottom of the module are straight so they align
properly with the connector in the terminal base.
WARNING: If you remove or insert the module while the 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.
4. Position the module (6) with its alignment bar (5) aligned with the groove (4) on
the terminal base.
5. Press firmly and evenly to seat the module in the terminal base unit, noting that
the module is seated when the latching mechanism (1) is locked into the module.
Remove debris wrapper before applying power to the module.

1794-TB3 and 1794-TB3S Terminal Base Wiring
WARNING: If you connect or disconnect wiring while the field-side 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.
To connect wiring for 1794-TB3 and 1794-TB3S bases, refer to the tables and figure and
complete the following.
1. Connect individual input wiring (A+, A-, B+, B-, Z+, Z-, G+, G-) for each
channel to numbered terminals on the 0…15 row (A) as indicated in the table
below.
2. If applicable, connect the encoder commons to any terminal on the 16…33 row
(B) for each input as indicated.
ATTENTION: To reduce susceptibility to noise, power analog modules and
digital modules from separate power supplies. Do not exceed a length of 3 m
(9.8 ft) for DC power cabling.
