1. DESCRIPTION - USE

. Module dedicated to Energy Management System (EMS CX3) use.
. Auxiliary and Fault signalling electronic module (CA+SD): indicates
contacts position (open or closed) and fault tripping of Legrand
modular associated device (MCB, RCBO, RCCB or Remote trip
head IS).

Symbol:

2. RANGE

. Cat. n° 4 149 29: electronic auxiliary contact (CA) + fault signalling
(SD).

Width:

. ½ module. 8,8 mm width.

3. OVERALL DIMENSIONS

4. PREPARATION -CONNECTION

Fixing:

. On symmetric rail EN/IEC 60715 or DIN 35 rail

Operating positions:

. Vertical, Horizontal, Upside down, On the side

Power Supply:

. Mandatory in 12 VDC via the specific Power supply module Cat n°4
149 45
. Two ways:
via specific communication patch cords (cat. nos 4 149 07/08/09) to
connect at the downstream through dedicated ports

via specific communication rails (cat. nos 4 149 01/02/03) to
connect at the rear through dedicated connectors.

EMS CX3 - Signalling Auxiliary Contact
(CA + SD)

Cat. N°: 4 149 29

4. PREPARATION –CONNECTION

(continued)

Manual action of the CA + SD:

. By the handle of the associated device.

Assembling:

. On the left side of Legrand MCB, IS, RCBO or RCCB
. No tools are required. Clipped by mean of plastic clamps on the
associated device.
. Assembling products in OFF position
. The switching device of signalling auxiliaries must fit into the
housing of the handle of the associated device.

List of allowed associations (General rules):

Three auxiliaries maximum which:

- two signalling auxiliaries
(Cat. nos 4 062 50/52/56/58/60/62/64/66, 4 149 29).

- only one control auxiliary
(Cat. nos 4 062 76/78/80/82/84/86/87).

. If signalling and control auxiliaries are associated on the same
circuit breaker, the control auxiliary must be placed to the left of the
signal auxiliary (ref. 4 062 5x / 6x or 4 149 29).

List of allowed associations (Particular rules):

. With MCB’s 1,5 modules per pole width:

- if a remote tripping auxiliary (Cat. nos 4 062 76/78/80/82/84/86/

87) is already mounted on this kind of device, only 1 module
width signalling auxiliaries (Cat. nos. 4 062 64/66) can be added.
In this set up the ½ module signalling auxiliaries will not operate.
Nothing changes for the other modular references.

. With an isolating switch DX3-IS:

- only one signalling auxiliary CA type (Cat. nos 4 062
50/56/58/62/64/66) or CA+SD (Cat. n° 4 149 29).

. With a remote trip head isolating switch DX3-IS, three auxiliaries
maximum which:

- one or two signalling auxiliaries CA type Cat. nos 4 062
50/56/58/62/64/66) or CA+SD (Cat. n° 4 149 29).

- one control auxiliary (Cat nos 4 062 4 062 76/78/80/82/84/86/

87).

. For devices 1 module per pole width:

. For devices 1,5 modules per pole width:

EMS CX3 - Signalling Auxiliary Contact
(CA + SD)

Cat. N°: 4 149 29

4. PREPARATION –CONNECTION

(continued)

Data connection (EMS CX3 modules inter-connection):

. Via specific communication patch cords (cat. nos 4 149 07/08/09)

Allow data transmission between the different EMS CX3 modules.
This type of connection is recommended when there are few EMS
CX3 modules, distributed all over the enclosure.

Implementing: with this configuration, the plastic protection cover of
the backside communication ports on the EMS CX3 module must be
keep on.

4. PREPARATION –CONNECTION

(continued)

Data connection (EMS CX3 modules inter-connection)

(continued)

:

. Via specific communication rails (cat. nos 4 149 01/02/03).

. Allow data transmission between the different EMS CX3 modules.
This type of connection is recommended when there are several
EMS CX3 modules on the same DIN row.

Implementing: with this configuration, the plastic protection cover of
the backside communication ports on the EMS CX3 module must be
removed.

EMS CX3 - Signalling Auxiliary Contact
(CA + SD)

Cat. N°: 4 149 29

4. PREPARATION –CONNECTION

(continued)

Data connection (EMS CX3 modules inter-connection)

(continued)

:

. Via a mix between specific communication patch cords and
communication rails in order to create a link between several rows

Two situations:

- Individually connected with communication rails.

The communication patch cord allows to connect two rows.

- Individually connected with communication patch cords &

communication rail.
The communication patch cords allow to connect EMS CX3
module on a row and to connect two rows.
