ATTENTION: Personnel responsible for the application of safety-related
programmable electronic systems (PES) shall be aware of the safety
requirements in the application of the system and shall be trained in using the
system.
ATTENTION: FLEX I/O systems are grounded through the DIN rail to chassis
ground. Use zinc plated yellow-chromate steel DIN rail to assure proper
grounding. The use of other DIN rail materials (for example, aluminum or
plastic) that can corrode, oxidize, or are poor conductors, can result in improper
or intermittent grounding. Secure DIN rail to mounting surface approximately
every 200 mm (7.8 in.) and use end-anchors appropriately.
ATTENTION: Do not remove or replace a Terminal Base unit while power is
applied. Interruption of the backplane can result in unintentional operation or
machine motion.
ATTENTION: For Class I Division 2 applications, use only Class I Division 2
listed or recognized accessories and modules approved for use within the 1794
platform.
ATTENTION: If this equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be impaired.
WARNING: When used in a Class I, Division 2, hazardous location, this
equipment must be mounted in a suitable enclosure with proper wiring
method that complies with the governing electrical codes.
WARNING: If you connect or disconnect wiring while the field-side power is
on, an electrical arc can occur. This could cause an explosion in hazardous
location installations. Be sure that power is removed or the area is
nonhazardous before proceeding.
