Safety Notes
WAGO-I/O-SYSTEM 751
AS-Interface Components IP20
1.4 Safety Notes
Attention
Switch off the system prior to working on bus modules!
In the event of deformed contacts, the module in question is to be replaced, as
its functionality can no longer be ensured on a long-term basis.
The components are not resistant against materials having seeping and
insulating properties. Belonging to this group of materials is: e.g. aerosols,
silicones, triglycerides (found in some hand creams).
If it cannot be ruled out that these materials appear in the component
environment, then additional measures are to be taken:
- installation of the components into an appropriate enclosure
- handling of the components only with clean tools and materials.
Attention
Cleaning of soiled contacts may only be done with ethyl alcohol and leather
cloths. Thereby, the ESD information is to be regarded.
Do not use any contact spray. The spray may impair the functioning of the
contact area.
The AS-Interface Slaves IP20 from the WAGO-I/O-SYSTEM 751 are open
components. They must only be assembled in housings, cabinets or in
electrical operation rooms. Access must only be given via a key or tool to
authorized qualified personnel.
The relevant valid and applicable standards and guidelines concerning the
installation of switch boxes are to be observed.
1.5 Scope
This manual describes the Digital Input Module 751-3502
AS-Interface Module 4IN 24V A/B of the modular WAGO-I/O-SYSTEM
751.
Handling, assembly and start-up are described in the manual of the Fieldbus
Coupler. Therefore this documentation is valid only in the connection with the

2.1.1.2 Description
The AS-Interface module 751-3502 is an economical solution for a fieldbus-
independent and flexible connection of actuators and sensors from the field
and the control cabinet. The module is in accordance with AS-Interface
specification V.3.0.
The module works in extended address area and can be set to one of 62
addresses ranging from 1A ... 31A resp. 1B … 31B.
The voltage for the sensors is supplied via the AS-Interface cable and is short
circuit protected.
The AS-Interface module 751-3502 provides 4 digital 24 V inputs.
Sensors, actuators, AS-Interface power supply and actuator supply are
connected using connectors from the WAGO Multi Connection System Mini.
LEDs indicate the status of inputs and outputs, the AS-Interface and actuator
supply as well as a short circuit or overload condition.

2.1.1.8 Assembly
The IP20 AS-Interface Slaves are snapped onto DIN 35 carrier rails. Please
ensure that the space for the connection of the female connectors is big
enough. The IP20 AS-Interface Slaves must only be used in enclosures,
cabinets or electrical service rooms. Only authorised qualified personnel are
allowed to access via key or tool.
Depending on the type of slave, 3- or 4-pole WAGO female connectors of
Series 734 (CAGE CLAMP®connection) for the connection of AS-Interface,
AUX, sensors or actuators are included in the delivery. The female connectors
are appropriate for the connection of solid, stranded and fine-stranded
conductors from 0.08 ... 1.5 mm² (AWG 28 ... 14) with a stripped length of
7 mm.
2.1.1.9 Start-up and diagnosis
Attention
Operating an AS-Interface network with components that do not comply with
the AS-Interface specification may lead to malfunctions or restrictions.
Please note the AS interface master manual and the manual for the start-up
tool WAGO-I/O-CHECK 2 (759-302) for start-up and diagnosis of the AS
interface slaves with AS interface master 750-655 from the WAGO-I/O-
SYSTEM 750.
For start-up and diagnosis of AS interface slaves with an AS interface master
or an AS interface programming device of another manufacturer, please note
the corresponding operating manuals.
