Assembling The Product; Connecting The Supply Voltage - Emerson AVENTICS PROFINET DDL Betriebsanleitung

5 Assembly
Danger of injury if assembled under pressure or voltage!
Assembling when under pressure or electrical voltage can lead to injuries and
damage to the product or system components.
1. Make sure that the relevant system component is without pressure and
voltage before you assemble the product.
2. Protect the system against being restarted.

5.1 Assembling the product

Danger of injury due to incorrect assembly!
Incorrect assembly can lead to uncontrolled product or system movements.
1. Make sure that the bus coupler is correctly fastened.
2. Make sure that the device is securely fastened with the correct tightening
torque.
1. Let the bus coupler acclimate itself for several hours before installation; other-
wise water may condense in the housing.
2. Make sure the relevant system part is without pressure and voltage.
3. Remove the four mounting screws.
4. Set the bus coupler in the desired position on the mounting plate (any) or
control cabinet (on the side).
5. Tighten the four M5 mounting screws (tightening torque: 6 Nm).

5.2 Electrically connecting the product
5.2.1 Connecting the DDL and bus coupler
The electrical connections of the bus coupler are established using threaded
M12x1 round plug connectors.
Attach the connectors to the bus coupler.
u
Material damage due to penetration of liquids and foreign objects!
Liquids and foreign objects could penetrate the plug connections if seals and
plugs are missing and cause damage to the product or system components.
1. Use round plug connectors with the IP65 protection class or better.
2. Make sure that the seals are integrated in the plug and not damaged.
3. Close all unused plug connectors with sealing caps (blanking plugs).
4. Make sure that all plugs are correctly connected before commissioning.

The valve coils are provided with voltage via the integrated X1S POWER SUPPLY
(4) plug.

Pin 1 24 V electronics
Pin 2 24 V valves
Pin 3 0 V (max. 4 A)
Pin 4 FE
The electronics of the bus coupler and the electronics of all I/O modules and ini-
tiators connected through the DDL are supplied via X1S, Pin 1 (for modules with-
out external power supply).
When using modules without an external power supply, the switching voltage for
the connected valves must be supplied via X1S, Pin 2.
The separate supply voltages via pin 1 and pin 2 make it possible to
switch off only the valves in an emergency OFF situation, while the
PLC, serial interfaces and initiators remain in operation. Shutting off
the supply voltage for the serial interface can cause the PLC to STOP.
Damage can occur if the device is assembled or disassembled under voltage/
load!
Inadvertently connecting and disconnecting the product or system parts under
voltage/load can cause damage.
Make sure that all relevant system parts are not under voltage before in-
u
serting or disconnecting plug connectors.
• Only use 4-pin M12 connection sockets where pin 5 is closed, in order to rule
out confusion with other connections.
• Make sure that the largest connection cross-section possible is selected, at
least 0.55 mm².
• Secure both supply voltages with external 3-A-T fuses.
The applied supply voltage is indicated by a green LED (5 V): The LED il-
luminates as soon as the electronics voltage > 18 V. See g Table 5.
The maximum permissible current in the 0 V line is limited to 4 A by
the plug connector.
Only use a shared power pack or a shared 0 V connection for the 24 V
power supply. This must be a power pack with safe isolation in accor-
dance with DIN EN 60742, classification VDE 0551.
