Intended use
CPX terminals are intended for installation in machines or
automation systems. Depending on the CPX bus node used,
they can be connected to a special field bus system and serve
to interrogate sensor signals and to control pneumatic and
electric actuators.
The individual CPX modules of the CPX terminal are docu
mented in specific manuals. The safety instructions listed in
the manuals must always be observed and the relevant CPX
module must only be used as intended. CPX modules and
cables are only to be used as follows:
 Only in an industrial environment
Asintended
Inoriginal status without unauthorised modifications.
Only the conversions or modifications described in the
documentation supplied with the product are permitted.
Inperfect technical condition.
When used together with commercially available compo
nents, such as sensors and actuators, the specified limits for
pressures, temperatures, electrical data, torques etc. must be
observed. Also observe the standards specified in the rele
vant chapters, as well as national and local laws and technical
regulations.
