The I/O module 750-496 shall only be installed and operated according to the
instructions in this manual and in the manual for the used fieldbus
coupler/controller.
Consider power layout of the WAGO-I/O-SYSTEM 750!
In addition to these operating instructions, you will also need the manual for the
used fieldbus coupler/controller, which can be downloaded at www.wago.com.
There, you can obtain important information including information on electrical
isolation, system power and supply specifications.

2.1.1 Subject to Changes
WAGO Kontakttechnik GmbH & Co. KG reserves the right to provide for any
alterations or modifications. WAGO Kontakttechnik GmbH & Co. KG owns all
rights arising from the granting of patents or from the legal protection of utility
patents. Third-party products are always mentioned without any reference to

2.1.2 Personnel Qualifications
All sequences implemented on WAGO-I/O-SYSTEM 750 devices may only be
carried out by electrical specialists with sufficient knowledge in automation. The
specialists must be familiar with the current norms and guidelines for the devices
and automated environments.
All changes to the coupler or controller should always be carried out by qualified
personnel with sufficient skills in PLC programming.

2.1.3 Use of the WAGO-I/O-SYSTEM 750 in Compliance with
Underlying Provisions
Fieldbus couplers, fieldbus controllers and I/O modules found in the modular
WAGO-I/O-SYSTEM 750 receive digital and analog signals from sensors and
transmit them to actuators or higher-level control systems. Using programmable
controllers, the signals can also be (pre-) processed.
The devices 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 devices in wet and dusty
environments is prohibited.
Operating the WAGO-I/O-SYSTEM 750 devices 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 “Device Description” > “Standards and Guidelines” in the manual
for the used fieldbus coupler/controller.
Appropriate housing (per 2014/34/EU) is required when operating the WAGO-
I/O-SYSTEM 750 in hazardous environments. Please note that a prototype test

Install the device only in appropriate housings, cabinets or in electrical
operation rooms!
The WAGO-I/O-SYSTEM 750 and its components are an open system. As such,
install the system and its components exclusively in appropriate housings,
cabinets or in electrical operation rooms. Allow access to such equipment and
fixtures to authorized, qualified staff only by means of specific keys or tools.

Do not exceed maximum current via power jumper contacts!
The maximum current to flow through the power jumper contacts is 10 A.
Greater currents can damage the contacts.
When configuring your system, ensure that this current is not exceeded.
If exceeded, insert an additional supply module.

Use supply modules for ground (earth)!
The I/O module has no power jumper contacts for receiving and transmitting the
earth potential. Use a supply module when an earth potential is needed for the
subsequent I/O modules.

Field supply must be provided!
An additional supply module must be used, which provides 24 V field supply
voltage via the power jumper contacts.

Use shielded signal lines!
Only use shielded signal lines for analog signals and I/O modules which are
equipped with shield clamps. Only then can you ensure that the accuracy and
interference immunity specified for the respective I/O module can be achieved
even in the presence of interference acting on the signal cable.
