WIRING
There are 2 ways to connect CX³ EMS
modules:
- Via the communication rail. To do this,
you need to remove the plastic protection
from the rear communication ports of the
modules.
To avoid damaging the rail or the
connections, the module should
not be moved along the
communication rail once fitted.
- Via cables which connect to the bottom
of each module.
Each CX³ EMS module has 2 bus
connectors.
The 2 types of connection can be
used in the same enclosure.
A module whose protection has
been removed can be used on a
single DIN rail. We recommend
protecting the module against any
contact by adding insulation of your
choice on the DIN rail.
