2.1.1 Subject to Changes

WAGO Kontakttechnik GmbH & Co. KG reserves the right to provide for any

alterations or modifications that serve to increase the efficiency of technical

progress. WAGO Kontakttechnik GmbH & Co. KG owns all rights arising from

the granting of patents or from the legal protection of utility patents. Third-party

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.

Only connect or disconnect lines when power is safely isolated!

The lines to the device can carry hazardous voltages and currents. Contact with

the lines when live can result in severe injury or death. Therefore, read and

observe the following safety rules before you perform work on the device:

1. Disconnect the respective system component from the power supply.

2. Secure the system component against unintentional restart.

3. Check if the voltage is positively isolated.

Version 1.2.1

Protect the components against materials having seeping and insulating

properties!

The components are not resistant to materials having seeping and insulating

properties such as: aerosols, silicones and triglycerides (found in some hand

creams). If you cannot exclude that such materials will appear in the component

environment, then install the components in an enclosure being resistant to the

above-mentioned materials. Clean tools and materials are imperative for handling

devices/modules.

Only connect to I/O modules with the same field power supply!

The I/O module 750-512 requires a field supply not equal to 24 VDC.

Therefore, this I/O module 750-512 shall only be connected to modules having

the same field power supply.

If using an adjacent I/O module designed for another field power supply, place an

appropriate supply module between this adjacent module and the I/O module

750-512.

Failure to observe these instructions may result in damage to properties or injuries

to people.

The I/O module receives the 230 VAC or 30 VDC potential for the field level

from an upstream I/O module or from the fieldbus coupler/controller via the

power contacts used as blade contacts. It then provides this potential to

subsequent I/O modules via the power contacts used as spring contacts.

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
