CPU module for Zone 2
Series 9442/35
3.1
Intended Use
The 9442/35 CPU module functions as a gateway between the IS1+ Remote I/O System and
the automation system. All supported communication protocols are in the CPU module and
can be selected by the user. In addition to the process values, other information such as
diagnostics, parameterisation and configuration are transmitted over the CPU module.
Communication with the I/O modules is implemented via the 9496 base and the 9494 Bus
-
Rail. Integration in control systems and plant asset management tools is implemented using
standards such as GSD, EDS, web servers and FDT/DTM.
The device is approved for use in hazardous areas of Zone 2 and in safe areas. The device
is intended for installation in areas with a degree of pollution of 1 or 2 in accordance with
IEC/EN 60664-1.
"Intended use" includes complying with these operating instructions and the other applicable
documents, e.g. the data sheet. Any other use of the device is not intended.
3.2
Personnel qualification
Qualified specialist personnel are required to perform the activities described in these
operating instructions. This primarily applies to work in the following areas:
• Product selection, project engineering and modification
• Mounting/dismounting the device
• Installation
• Commissioning
• Maintenance, repair, cleaning
Specialists who perform these tasks must have a level of knowledge that meets applicable
national standards and regulations.
Additional knowledge is required for tasks in hazardous areas! R. STAHL recommends
having a level of knowledge equal to that described in the following standards:
• IEC/EN 60079-14 (Electrical installations design, selection and erection)
• IEC/EN 60079-17 (Inspection and maintenance of electrical installations)
• IEC/EN 60079-19 (Equipment repair, overhaul and reclamation)
3.3
Residual risks
3.3.1 Explosion hazard
Despite the device's state-of-the-art design, explosion hazards cannot be entirely eliminated
in hazardous areas.
Perform all work steps in hazardous areas with the utmost care at all times!
Transport, store, plan, install and operate the device in compliance with the technical data
exclusively (see the "Technical data" chapter).
Possible moments of danger (residual risks) can be categorised according to the following
