Digital Input Module NAMUR Ex i Inputs, 16 Channels Series 9470/22
✗
For installation in hazardous areas the module has to be
fitted into an enclosure which is certified appropriate to the
requirements (e.g. R. STAHL Type 8126).
Assembly and Installation
The national installation instructions
(e.g. IEC/EN 60079-14) must be observed.
Intrinsically-safe and non-intrinsically safe circuits must
not be used in a common cable duct!
Ensure that there is a distance of at least 50 mm
between connection facilities of intrinsically-safe and
non-intrinsically safe circuits!
The screens on the fieldbus cabling must be connected
to the equipotential bonding system of the hazardous
area!
For this purpose the screens on the fieldbus cabling
must be connected to the screen bars installed in the
enclosures as close as possible to the entry point!
The screen bars must also be connected to the
mounting plate close to the entry points for the fieldbus
cabling by the shortest possible route!
The module and plug-in terminals X1 and X2 can be
safely connected or disconnected during operation in
potentially explosive area (hot swap).
Assembly on the BusRail
• Connect the field devices to the plug-in terminals X1 and X2.
A connection diagram is imprinted on the rear side of
the symbol label at the protective cover.
• Position the module vertically at the intended slot of the
BusRail.
• Engage the module by slightly pressing it.
• If necessary, engage the partition between the modules.
Operation of the module is permissible only in the
following assembly positions:
Vertical assembly with plug-in terminals below, on the
left or right.
• Plug in the plug-in terminals X1 and X2 into the module and
secure it by means of screws against loosening.

Replacing the Module
Before removing the partition between the module and
a Zone 2 module the plug-in terminals X1 and X2 must
be pulled out of the module to be replaced!
When replacing the module with a module identical in
construction the previous parameters are applied.
No further settings are necessary.
When replacing the module by another module it is
identified correctly at the slot, since the previously set
parameters do not suit this module, it reports a
configuration fault. The module must be either
parameterised again or it is necessary to connect the
module of the right type.
• Loosen the screws of the plug-in terminals X1 and X2.
• Pull out the terminals from the module.
• If necessary, remove the partition.
• Pull the red detent lever of the module upwards to unlock the
module.
• Remove the module vertically from the BusRail.
• Position the new module vertically onto the BusRail and
engage it by slightly pressing it.
• If necessary, engage the partition between the modules.
• Plug in the plug-in terminals X1 and X2 into the module and
secure it by means of screws against loosening.
Maintenance and Servicing
The module is maintenance-free.
• Observe the function according to designated use.
• Adhere to the directives according to IEC/EN 60079-17.
• Adhere to permissible temperatures according to
IEC/EN 60079-0.
Repair
For repair send the module to the responsible sales organisation
(address see www.stahl.de).
Repair is to be performed only by the manufacturer.
Transport and Storage
Transport and storage are permitted only in the original
packaging.
Disposal
Observe the national standards for refuse disposal.
