effects of electrical interference. Analog inputs are highly susceptible to
electrical noise. Electrical noise coupled to the analog inputs will reduce the
performance (accuracy) of the module. Group your modules to minimize adverse
effects from radiated electrical noise and heat. Consider the following conditions
when selecting a location for the analog module. Position the module:
Away from sources of electrical noise such as hard-contact switches,
•
relays, and AC motor drives.
•
Away from modules which generate significant radiated heat. Refer to
the module's heat dissipation specification.
In addition, route shielded, twisted-pair, analog input wiring away from any high
voltage I/O wiring.
POSSIBLE EQUIPMENT OPERATION
Before installing or removing your module, always disconnect power
from the SLC 500 system and from any other source to the module (in
other words, do not "hot swap" your module), and disconnect any devices
wired to the module.
Failure to observe this precaution can cause unintended equipment
operation and damage.
When inserting your module into the rack, you do not need to remove the
supplied 16-position terminal block from the module. If, however, you do
remove the terminal block, apply the supplied write-on label to the terminal
block, and use the write-on label to identify your module's location.
