European Hazardous Location Approval
The following input modules are European Zone 2 approved: 1794-IB8, -IB16, and
-IB16K.
European Zone 2 Certification (The following applies when the product bears the
Ex Marking)
This equipment is intended for use in potentially explosive atmospheres as defined by
European Union Directive 94/9/EC and has been found to comply with the Essential Health
and Safety Requirements relating to the design and construction of Category 3 equipment
intended for use in potentially explosive atmospheres, given in Annex II to this Directive.
Compliance with the Essential Health and Safety Requirements has been assured by
compliance with EN
60079-15 and EN 60079-0.
Observe the following additional Zone 2 certification requirements.
• This equipment is not resistant to sunlight or other sources of UV
radiation.
• This equipment must be installed in an enclosure providing at least
IP54 protection when applied in Zone 2 environments.
• This equipment shall be used within its specified ratings defined
by Allen-Bradley.
• Provision shall be made to prevent the rated voltage from being
exceeded by transient disturbances of more than 40% when
applied in Zone 2 environments
• This equipment must be used only with ATEX certified backplanes.
• Secure any external connections that mate to this equipment by
using screws, sliding latches, threaded connectors, or other means

• Do not disconnect equipment unless power has been removed or
the area is known to be nonhazardous.
Environment and Enclosure
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 considered Group 1, Class A industrial equipment
according to IEC/CISPR 11. Without appropriate precautions, there may be
difficulties with electromagnetic compatibility in residential and other
environments due to conducted and radiated disturbances.
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
requirements.
• NEMA Standards 250 and IEC 60529, as applicable, for explanations
of the degrees of protection provided by different types of enclosure.
This product is 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.

The module mounts on a 1794 terminal base.
During mounting of all devices, be sure that all debris (such as metal chips
and wire strands) is kept from falling into the module. Debris that falls into
the module could cause damage on power up.
1. Rotate the keyswitch (1) on the terminal base (2) clockwise to position 2 as
required for this type of module.
2. Make certain the flexbus connector (3) is pushed all the way to the left to
connect with the neighboring terminal base/adapter. 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 will
align properly with the connector in the terminal base.
If 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.
4. Position the module (4) with its alignment bar (5) aligned with the groove
(6) on the terminal base.
5. Press firmly and evenly to seat the module in the terminal base unit. The
module is seated when the latching mechanism (7) is locked into the
module.
Connect Wiring for the 1794-IB8, -IB16, and -IB16K using a 1794-TB3 or -TB3S
1. Connect individual input wiring to numbered terminals on the 0…15 row
(A) as indicated in the following table on the next page.
2. Connect the associated +V DC power lead of the input device to the
corresponding terminal on the 34…51 row (C) for each input as indicated
in the following table. (The +V power terminals of row (C) are internally
connected together.)
3. Connect the associated input common (3-wire devices only) to the
corresponding terminal on the 16…33 row (B) for each input as indicated
in the following table. (Commons are internally connected together.)
4. Connect +V DC power to terminal 34 on the 34…51 row (C).
5. Connect DC common to terminal 16 on the 16…33 row (B).
6. If daisychaining power to the next terminal base, connect a jumper from
terminal 51 (+V DC) on this base unit to terminal 34 on the next base unit.
7. If continuing DC common to the next base unit, connect a jumper from
terminal 33 (common) on this base unit to terminal 16 on the next base
unit.
