Planning

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
W
ON ORKS
 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.
