Overview
Engineering with CARE
During CARE engineering, the type of I/O modules, terminal
assignment and module configuration are defined
depending on the application.
Planning
In this step, the following has to be defined, if applicable:
Power supply
Fusing
Earth grounding
Lightning protection
Panel Bus wiring
Design of a L
ON
W
ORKS
network
Design of a C-Bus network
Useful accessories
Cable selection
Transformer Selection
Note
In Europe the system transformer(s) must be safety isolating
transformers according to IEC61558-2-6.
In the U.S.A. and Canada, NEC Class-2 transformers must
be used.
Power Consumption
When selecting the appropriate transformer, take into
account the number of individual modules, accessories, and
field devices in determining the total power consumption.
