The I/O module 750-495/040-00x shall only be installed and operated according
to the instructions in this manual, in the system description for the WAGO-I/O-
SYSTEM 750 XTR and in the manual for the used fieldbus coupler/controller.
Consider power layout of the WAGO-I/O-SYSTEM 750 XTR!
In addition to these operating instructions, you will also need the system
description “Design Notes XTR – Guidelines and Recommendations for
Increasing Operational Safety” and 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.

Fieldbus couplers, 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 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 or 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 certificate must be obtained that confirms the correct installation of
the system in a housing or switch cabinet.
The implementation of safety functions such as EMERGENCY STOP or safety
door monitoring must only be performed by the F-I/O modules within the modular
WAGO-I/O-SYSTEM 750. Only these safe F-I/O modules ensure functional
safety in accordance with the latest international standards. WAGO's
interference-free output modules can be controlled by the safety function.

Avoid electrostatic discharge!
The devices are equipped with electronic components that may be destroyed by
electrostatic discharge when touched. Please observe the safety precautions
against electrostatic discharge per DIN EN 61340-5-1/-3. When handling the
devices, please ensure that environmental factors (personnel, work space and
packaging) are properly grounded.

Use only direct current (DC) for insulation testing!
Both the system voltage and field voltage side are capacitively coupled to the
DIN-rail. If an I/O module is mounted on the DIN-rail, application of an AC voltage
between the DIN-rail and at least one of these two potentials can lead to the
destruction of the module.
Use only direct current (DC) for insulation testing. To avoid destroying the I/O
module, you must discharge it completely before applying the test voltage again.

The 750-495/040-00x 3-Phase Power Measurement Module (also referred to by
the short name “I/O module”) allows measurement of electrical data in a 3-phase
supply network.
The I/O module provides a large number of measured quantities, allowing
comprehensive analysis of the 3-phase network. These measured values allow
the operator optimized control of the supply to a drive or machine, protecting the
system from damage and failure.
The measured values provided indicate the load type (inductive or capacitive)
and whether it is an energy consumer or producer, for example. This allows e.g.
visualization as a 4-quadrant display, as has been implemented in the display of
the measured values in WAGO-I/O-CHECK.
The voltages of the three phases are connected to CAGE CLAMP® connections
L1, L2, L3 and N, the currents are connected via current transformers to CAGE
CLAMP®connections I1+ and I1−, I2+ and I2−, I3+ and I3− and IN+ and IN−, or
via Rogowski coils to CAGE CLAMP®connections RC1+ and RC1−, RC2+ and
RC2−, RC3+ and RC3− and RCN+ and RCN−. On the basis of these input
signals, the I/O module determines the various AC measured quantities, such as
voltage and current, reactive, apparent and effective power, energy consumption,
power factor, phase angle and frequency. Harmonic analysis (current/voltage) is
also possible for a selectable phase up to the 41st harmonic. The measured
quantities are available in the process image, without requiring high processing
power from the controller.
In firmware versions 05 and above, the I/O module offers the option of
distinguishing the following topologies:
• “4-Wire Wye” (default) for the measurement on 3 line conductors in
3-phase and 1-phase networks with a neutral conductor
• “3-Wire Wye/Delta for the measurement in 3-phase networks without a
neutral conductor using the 2-wattmeter method (Aron circuit/Blondel’s
Theorem)
• “4-Wire Wye, 2 Phases” for the measurement on 2 line conductors in
3-phase networks with a neutral conductor
• “Artificial Star Point” for the measurement in 3-phase networks without a
neutral conductor using the 3-wattmeter method (ASP)
You can find information on the possible connection diagrams in the sections
“Power Measurement with 4-Wire Connection on Y Networks” and “Power
Measurement with 3-Wire Connection on Y/Δ Networks.”
Each of these sections is followed by sections describing the measured values
provided.

Manual
Version 1.2.0
The 750-495/040-000 I/O module measures currents up to 1 A, the
750-495/040-001 version measures currents up to 5 A, and the 750-495/040-002
measures currents up to 500 A (RT500) and 2000 A (RT2000) using Rogowski
coils.
With firmware versions 03 and above, RC70, RC125 and RC175 are also
supported for measurements up to 4000 A. Firmware versions 05 and above
support user-defined coils.
The input of the 750-495/040-002 version processes secondary voltages of
Rogowski coils up to 88 mVRMS AC. The maximum primary current resulting from
this is calculated according to the following formula:

Explanation of the factors:

RRC: Internal resistance in ohms [Ω]
Always use current transformers
For measuring current, it is essential to use current transformers.
For line voltages ULN ≤ 400 V, current transformers with basic insulation are
required. For line voltages ULN > 400 V, current transformers with reinforced
insulation are required.
Otherwise, touch-proof protection from the system may no longer be given in the
event of a fault. This can cause electric shock or burns. Furthermore, current
measurement without a current transformer can lead to a short circuit in the
power network and destruction of the I/O module.

Mixed operation (standard/XTR modules) within a node is possible when groups
of modules are electrically isolated on the field side (i.e., electrically isolated
power supply).
