■ CX³ EMS communication
rail protection:
The unused part of the communication rail
must be protected by the plastic cover.
The cover can be cut to the required length.
A visible rail which is not protected
against direct contact can be
responsible for a short-circuit on
the CX³ EMS bus.
■ CX³ EMS communication cable:
Communication cables are available in
3 lengths: 250, 500, 1000 mm.
You can make your own cable.
We cannot guarantee it will work.
We offer an extension connector which can
be used to extend the cable length.
Cables link the CX³ EMS modules.
Cables link 2 communication rails by
linking 2 CX³ EMS modules.
The maximum length of a cable or
“ connectors” must be
less than 3 m.
