Power Supply; Led - Emerson AVENTICS Modbus TCP Manual De Instrucciones

The tightening torque for the M4x0.7 nut (SW7) on the ground screw is 1.25 Nm
+0.25.
Fieldbus connection
The X7E1 (5) and X7E2 (6) fieldbus connections are designed as integrated M12
sockets, female, 4-pin, D-coded.
For pin assignments of the fieldbus connections see g Table 4. The view shown
displays the device connections.

Housing Ground
The AES series bus coupler for Modbus TCP has a 100 Mbit full duplex 2-port
switch, so that several AES series devices for Modbus TCP can be connected in se-
ries. As a result, the controller can be connected to either fieldbus connection
X7E1 or X7E2. Both fieldbus connections are identical.
Fieldbus cable
Danger caused by incorrectly assembled or damaged cables!
The bus coupler may be damaged.
Only use shielded and tested cables.
u
Faulty wiring!
Faulty wiring can lead to malfunctions as well as damage to the network.
1. Comply with the specifications for Modbus TCP.
2. Only a cable that meets the fieldbus specifications as well as the connection
speed and length requirements should be used.
3. In order to assure both the protection class and the required strain relief,
the cable and plug assembly must be done professionally and in accor-
dance with the assembly instructions.
4. Never connect the two fieldbus connections X7E1 and X7E2 to the same
switch/hub.
5. Make sure that you do not create a ring topology without a ring master.

Power supply

Electric shock due to incorrect power pack!
Danger of injury!
1. The units are permitted to be supplied by the following voltages only:
24 V DC SELV or PELV circuits, whereby each of the DC supply circuits must
be provided with a DC-rated fuse which is capable of opening at a current of
6.67 A in 120 s or less, or
24 V DC circuits which fulfill the requirements of a limited-energy circuit ac-
cording to clause 9.4 of standard UL 61010-1, 3rd edition, or
24 V DC circuits which fulfill the requirements of limited power sources ac-
cording to clause 2.5 of standard UL 60950-1, 2nd edition, or
24 V DC circuits which fulfill the requirements of NEC Class II according to
standard UL 1310.
2. Make sure that the power supply of the power pack is always less than
300 V AC (outer conductor – neutral wire).
The X1S power supply connection (7) is an M12 plug, male, 4-pin, A-coded.

• The voltage tolerance for the electronic components is 24 V DC ±25%.
• The voltage tolerance for the actuator voltage is 24 V DC ±10%.
• The maximum current for both power supplies is 4 A.
• The power supplies are equipped with internal electrical isolation.

Fig. 6: FE connection
To discharge the EMC interferences, connect the FE connection (8) on the bus
u
coupler via a low-impedance line to functional earth.
The line cross-section must be selected according to the application.

4.1.2 LED

The bus coupler has 6 LEDs.
The table below describes the functions of the LEDs. For a comprehensive de-
scription of the LEDs, see section
