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.

received via the CAGE CLAMP® connections AI 1 or AI 2.
The channels have a common reference potential and a shield connection.
The shield connection is fed directly to the carrier rail and contact is made

automatically by snapping the module onto the rail.

The assignment of the connections is described in the “Connectors” section.
Connection examples are shown in section “Connecting Devices” > … >

“Connection Example(s)”.

The input signal is electrically isolated and transmitted with a resolution of 16
bits.

The operational readiness and the trouble-free internal data bus communication of
the channels are indicated via a green function LED.

One red error LED per channel indicates when the measuring range is exceeded or
falls below for the respective channel.

The meaning of the LEDs is described in the “Display Elements” section.

Power to the internal electronics is supplied via internal data bus.

The I/O module 750-476 (2AI ±10V DC S.E.) receives the 24 V voltage supply
for the field level from an upstream I/O module or from the fieldbus
coupler/controller via blade-formed power jumper contacts. It then provides these
potentials to subsequent I/O modules via spring-formed power jumper 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
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.

750-476 2AI ±10V DC S.E.

With consideration of the power jumper contacts, the individual modules can be
arranged in any combination when configuring the fieldbus node. An arrangement
in groups within the group of potentials is not necessary.

The I/O module 750-476 can be used with all fieldbus couplers/controllers of the
WAGO-I/O-SYSTEM 750 (except for the economy types 750-320, -323, -324
and -327).
