CAUTION!
Risk of explosion!
Do not open, re-charge or disassemble a lithium battery. Attempts to charge
lithium batteries lead to overheating and possible explosions.
Protect them from heat and fire and store them in a dry place.
Never short-circuit or operate lithium batteries with the polarities reversed. The
batteries are likely to overheat and explode. Avoid chance short circuiting and
therefore do not store batteries in metal containers and do not place them on
metallic surfaces. Escaping lithium is a health hazard.
Environment considerations
Recycle exhausted batteries. Dispose batteries in an environmentally conscious
manner, in accordance to local-authority regulations.
This equipment is intended for use in a Pollution Degree 2 industrial environ-
ment, in overvoltage Category II applications (as defined in IEC publication
60664-1), at altitudes up to 2.000 meters without derating.
This equipment is considered Group 1, Class A industrial equipment according
to IEC/CISPR Publication 11. Without appropriate precautions, there may
be potential difficulties ensuring electromagnetic compatibility in other environ-
ments due to conducted as well as radiated disturbance.
This equipment is supplied as "open type" equipment. It must be mounted
within an enclosure that is suitably designed for those specific environmental
conditions that will be present and appropriately designed to prevent personal
injury resulting from accessibility to live parts. The interior of the enclosure must
be accessible only by the use of a tool. Subsequent sections of this publication
may contain additional information regarding specific enclosure type ratings that
are required to comply with certain product safety certifications.
Refer to NEMA Standards publication 250 and IEC publication 60529, as appli-
cable, for explanations of the degrees of protection provided by different types
of enclosure. Also see the appropriate sections in this manual.
2.4 Overall information (valid for complete AC500 product family)
2.4.1 Serial I/O bus
The synchronized serial I/O bus is the I/O data bus for the I/O modules connected with the
processor modules or communication interface modules. Through this bus, I/O and diagnosis
data are transferred.
Up to 10 I/O terminal units (for 1 I/O module each) can be added to one terminal base or to one
AC500-eCo processor module. The I/O terminal units and the AC500-eCo I/O modules, have
a bus input at the left side and a bus output at the right side. Thus the length of the I/O bus
increases with the number of attached I/O modules.
