Notes and Symbols used in this manual
This symbol calls attention to items which "must" be considered and implemented
when designing and building an AADvance controller for use in a Safety
Instrumented Function (SIF). It appears extensively in the AADvance Safety Manual.
Note: Notes are used extensively to provide important information about the
product.
Standard Warnings and Cautions
WARNING ELECTRICAL ARCS AND EXPLOSION RISK IN HAZARDOUS
AREAS
If you connect or disconnect wiring, modules or communications cabling while
power is applied, an electrical arc can occur. This could cause an explosion in
hazardous location installations. Do not remove wiring, fuses, modules or
communications cabling while circuit is energized unless area is known to be
non hazardous.
Failure to follow these instructions may result in personal injury.
WARNING MAINTENANCE
Maintenance must be carried out by people who are experienced in working on
electronic equipment and in particular safety related systems.They should have
knowledge and experience of local operating and safety standards. Failure to
follow these recommendations may result in situations that can lead system
damage and even personal injury.
CAUTION RADIO FREQUENCY INTERFERENCE
Most electronic equipment is influenced by Radio Frequency Interference.
Caution should be exercised with regard to the use of portable communications
equipment around such equipment. Signs should be posted in the vicinity of the
equipment cautioning against the use of portable communications equipment.
CAUTION HEAT DISSIPATION AND ENCLOSURE POSITION
System and field power consumption by modules and termination assemblies is
dissipated as heat. You should consider this heat dissipation on the design and
positioning of your enclosure; e.g. enclosures exposed to continuous sunlight
will have a higher internal temperature that could affect the operating
temperature of the modules. Modules operating at the extremes of the
temperature band for a continuous period can have a reduced reliability.
