GENERAL SAFETY INFORMATION
Safety instructions for installation and operating personnel
See Appendix on ATEX certification for countries in EEC, or governed by these standards.
The operating instructions provided here contain essential safety instructions for installation personnel and those engaged in the
operation, maintenance and servicing of the equipment.
Before commencing installation or commissioning:
◆Read and understand the contents of this manual
◆Ensure installation and operating personnel have received adequate training for this task
◆Ensure that any operating instructions are fully understood by the personnel responsible.
◆Observe national and local installation and mounting regulations (e.g. IEC 60079-14).
During operation:
◆Make the relevant instructions available at all times to the operating personnel.
◆Observe safety instructions.
◆Observe national safety and accident prevention regulations.
◆Operate the equipment within its published specification.
◆Servicing, maintenance work or repairs not described in this manual must not be performed without prior agreement with the
manufacturer.
◆Any damage to this equipment may render its explosion protection null and void.
◆No changes to any of the components that might impair their explosion protection are permitted.
If any information provided here is not clear:
◆Contact Eaton’s MTL product line or one of its representatives.
Note: Improper installation and operation of the enclosure can result in the invalidation of the guarantee.
WARNING!
Failure to comply with these instructions can endanger the lives or health of personnel and
risk damage to the plant and the environment.
WARNING!
The responsibility for planning, installation, commissioning, operation and maintenance,
particularly with respect to applications in explosion-hazard areas, lies with the plant
operator.

1 OVERVIEW
The 9107-22 power supply systems provide an intrinsically safe field network for Foundation
fieldbus™ systems in hazardous areas. It is intended for use with host cotrol systems equipped with
H1 interface cards that do not need to draw current from the fieldbus segment in order to operate.
Such systems include:
• ABB IndustrialIT with LD800HSE Linking Device
• Softing FG-100 FF/HSE Linking Device
The output of the power supply modules complies with the Fieldbus Intrinsically Safe Concept
(FISCO) model, in accordance with IEC standard 60079-27 (2006). The key advantages of FISCO
over earlier ‘Entity’ model installations to FF-816 are higher available field current and reduced
safety documentation, while retaining the ability to conduct maintenance while energised and
without ‘gas clearance’.
The 9107-22 system builds on the MTL 912x-IS range of power supplies, which have become
established as the industry standard solution for FISCO networks. The systems now achieve higher
levels of overall system availability by providing redundancy of the power modules.
When used with intrinsically safe versions of MTL-Relcom Megablock field wiring hubs, the power
supply systems allow complete FISCO networks to be assembled for even the most demanding
process applications. The data sheet for the 9107-22 is referenced on the opposite page.
2 DESCRIPTION
2.1 Architecture
Each IS fieldbus segment is powered by a redundant pair of pluggable FISCO power supply
modules. The modules operate in active/hot standby mode, ensuring that the fieldbus segments are
continually powered.
In the event of a failure of an active power supply module, the field circuit is automatically transferred
to the standby module. The change-over is managed by Supply Arbitration Modules (SAMs), which
monitor the health of the FISCO power supplies while maintaining intrinsic safety requirements
during the transition to the standby module. The SAMs are also duplicated and replaceable,
meaning that there are no non-redundant system components.
Switch-over is achieved rapidly and in accordance with Foundation fieldbus™ specifications,
and without risk of losing fieldbus devices from the bus. A combination of LED diagnostics and
alarm signalling provides failure notification of FISCO power supplies and SAMs, allowing failed
hardware to be identified and full redundancy to be restored by module replacement.
