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. The same applies to
engineering with COACH (which is possible starting with
COACH version 2.02).
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
ONWORKS 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.
Current Requirement
When selecting the appropriate transformer, take into
account the number of individual modules, accessories, and
field devices in determining the total current requirement.
