2.1.3 Use of the 750 Series in Complianc e wit h Unde rlying Provisions

Couplers, controllers and I/O modules found in the modular WAGO-I/O­SYSTEM 750 receive digital and analog signals from sensors and transmit them
to the actuators or higher-level control systems. Using programmable controllers,
the signals can also be (pre-) processed.

The components have been developed for use in an environment that meets the
IP20 protection class criteria. Protection against finger injury and solid impurities
up to 12.5 mm diameter is assured; protection against water damage is not
ensured. Unless otherwise specified, operation of the components in wet and
dusty environments is prohibited.

Operating 750 Series components in home applications without further measures
is only permitted if they meet the emission limits (emissions of interference)
according to EN 61000-6-3. You will find the relevant information in the section
on "WAGO-I/O-SYSTEM 750"  "System Description"  "Technical Data" in
the manual for the used fieldbus coupler/controller.

4.1 Assembly Sequence

All system components can be snapped directly on a carrier rail in accordance
with the European standard EN 50022 (DIN 35).

The reliable positioning and connection is made using a tongue and groove
system. Due to the automatic locking, the individual components are securely
seated on the rail after installation.

Starting with the coupler/controller, the I/O modules are assembled adjacent to
each other according to the project design. Errors in the design of the node in
terms of the potential groups (connection via the power contacts) are recognized,
as the I/O modules with power contacts (male contacts) cannot be linked to I/O
modules with fewer power contacts.

Risk of injury due to sharp-edged male contacts!

The male contacts are sharp-edged. Handle the module carefully to prevent injury.

Connect the I/O modules in the required order!

Never plug I/O modules from the direction of the end terminal. A ground wire
power contact, which is inserted into a terminal without contacts, e.g. a 4-channel
digital input module, has a decreased air and creepage distance to the neighboring
contact in the example DI4.

Assemble the I/O modules in rows only if the grooves are open!

Please take into consideration that some I/O modules have no or only a few power
jumper contacts. The design of some modules does not allow them to be
physically assembled in rows, as the grooves for the male contacts are closed at
the top.

Don't forget the end module!

Always plug an end module 750-600 onto the end of the fieldbus node! You must
always use an end module at all fieldbus nodes with the WAGO I/O System 750
fieldbus couplers/controllers to guarantee proper data transfer.

Use caution when interrupting the PE!

Make sure that people or equipment are not placed at risk when removing an I/O
module and the associated PE interruption. To prevent interruptions, provide ring
feeding of the ground conductor, see section "Grounding/Ground Conductor" in

5.1 Connecting a Conductor to the CAGE CLAMP®

The WAGO CAGE CLAMP® connection is appropriate for solid, stranded and
finely stranded conductors.

Only connect one conductor to each CAGE CLAMP® connection!

Only one conductor may be connected to each CAGE CLAMP® connection.
Do not connect more than one conductor at one single connection!

If more than one conductor must be routed to one connection, these must be
connected in an up-circuit wiring assembly, for example using WAGO feed­through terminals.

Exception:

If it is unavoidable to jointly connect 2 conductors, then you must use a ferrule to
join the wires together. The following ferrules can be used:
Length 8 mm
Nominal cross section
WAGO Product 216-103 or products with comparable properties.

1. To open the CAGE CLAMP® insert the actuating tool into the opening

above the connection.

1 mm2 for 2 conductors with 0.5 mm2 each

max.

2. Insert the conductor into the corresponding connection opening.

3. To close the CAGE CLAMP® simply remove the tool - the conductor is

then clamped firmly in place.

Mapping of process data in the process image of fieldbus systems

The representation of the process data of some I/O modules or their variations in
the process image depends on the fieldbus coupler/controller used. Please take
this information from the section "Fieldbus Specific Design of the Process Data"
included in the description concerning the process image of the corresponding
coupler/controller.

The analog output module 750-585 transmits 16-bit measured values and 8
optional status bits per channel.
The digitalized output value is transmitted in a data word (16 bits) as output byte
0 (low) and output byte 1 (high) via the process image of the
fielbuscoupler/controller.
The output current ranging from 0 mA to 20 mA is scaled on the numerical values
ranging from 0x0000 to 0x7FFF.
This value is represented with a 12 bit resolution on bit B3 ... B14. The three least
