Safety Notes
WAGO-I/O-SYSTEM 750
I/O Modules
1.4 Safety Notes
Warning
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 WAGO-I/O-SYSTEM 750 and its components are an open system. It
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.
ESD (Electrostatic Discharge)
The modules are equipped with electronic components that may be destroyed
by electrostatic discharge. When handling the modules, ensure that the
environment (persons, workplace and packing) is well grounded. Avoid
touching conductive components, e.g. gold contacts.
1.5 Scope

2.1.1.2 Description
The overvoltage protection module 750-626 is used to supply a fieldbus node.
This module has a filter for the 24 V system power supply and is equipped
with surge suppression for both the system and field side power supply via
power jumper contacts.
The WAGO-I/O-SYSTEM 750 can also be used in shipping industry
applications. Suitable onshore and offshore installations are: platforms,
loading facilities, cranes, monitor systems for containers, and other onboard
systems. This is possible via certification under the standards of leading
agencies such as Germanischer Lloyd and Lloyd‘s Register. Proper system
operation is ensured (certified) by using this filter module.

Warning
The maximum current of the filter module is 10 A. When configuring the
system it is important not to exceed the maximum/sum current. However, if
such a case should occur, another supply module must be added.
The filter module 750-626 can be used with all couplers/controllers of the
WAGO-I/O-SYSTEM 750.

Fig. 2.1.1-1: Power supply concept g060203e
The 24 V system power supply of the coupler / controller must be filtered
using the filter module 750-626 and protected against overvoltages.
The 24 V field power supplies must be protected against overvoltage using the
filter modules 750-624 or 750-626.
When supplying the ground (earth) potential via the power jumper contacts or
if a fuse protection or monitoring of the field power supply is required, a
supply module 750-601 (24 V power supply with fuse), 750-602 (24 V power
supply without fuse) or 750-610 (24 V power supply with fuse and
diagnostics) should be used in addition to the filter module 750-626.
Otherwise the use of a supply module is not required in addition to the filter
module 750-626. The downstream modules can then be directly supplied via
the power jumper contacts of the filter module 750-626.
For each additional 24 V field side power supply, a filter module 750-624 is to
be used in addition to the supply module 750-601, 750-602 or 750-610.
No filter module is required using 230 V field side power supply.
