2.4 Notes on electrostatically sensitive equipment
NOTICE
Electrostatic sensitive product
The assemblies might get damaged.
Ensure sufficient grounding of persons and working material!
Handling
Murrelektronik assemblies include highly integrated MOS com-
ponents. These components are extremely sensitive to over-
voltage occurring, for example, due to electrostatic discharge.
Assemblies at risk are marked with the adjacent symbol.
The symbol is affixed to assemblies, sub-racks or packaging
and indicates electrostatically sensitive equipment. These as-
semblies may become irreparably damaged by voltage and energy levels
which are far below the perception levels of human beings.
If a person who is not electrostatically discharged handles electrostatically
sensitive equipment, voltages may be produced. They may damage compo-
nents, impair the functioning of assemblies or render assemblies inoperative.
Frequently, assemblies thus damaged cannot directly be recognized as faulty.
The fault may only show up after prolonged operation.

For your own safety
User manual 57120_hdb_en_12 10 / 70
Components damaged by electrostatic discharge may produce temporary
faults in case of temperature changes, vibrations or load changes.
Only with a consistent use of protective devices and a responsible compliance
of the instructions for use can you avoid malfunctions or failures of the elec-
trostatically sensitive equipment.
Shipping For shipping electrostatically sensitive equipment, use always the original
packaging.
Measurements Observe the following notes for measurements on electrostatically sensitive
equipment:
Discharge potential-free measuring instrument briefly
Ground the measuring instruments used

For your own safety
User manual 57120_hdb_en_12 11 / 70
2.5 EMC installation guidelines
Industrial use The Cube20S is an electronic device manufactured according to the current
state-of-the-art standards. Both the robust mechanical construction and the
design of the electronic components make it ideal for industrial use.
To guarantee a trouble-free operation, observe the following rules when in-
stalling the device in systems. Otherwise, the high interference immunity and
resistance to damage of the device may become partially ineffective.
The interference immunity of the entire system considerably depends on the
correct installation, location and wiring.
1 | For safe operation, check the installation regulations stipulated by the
manufacturer of the controller.
2 | Bring them in line with the recommendations for an EMC-compatible de-
sign.
3 | Then install Cube20S.
2.6 Notes on spare parts and accessories
Spare parts
Only use the original spare parts or spare parts by other manufacturers ex-
pressly authorized by Murrelektronik GmbH.
Check the function of the device after having replaced a component.
Accessories
The use of accessories may alter the device function. Use only accesso-
ries authorized by Murrelektronik GmbH.
Observe the enclosed instructions of the accessories when installing
them.

System description
User manual 57120_hdb_en_12 13 / 70
3 System description
Overview The Cube20S system is a modular automation system mounted on a 35 mm
DIN rail in the control cabinet.
Using 2-, 4- and 8-channel expansion modules, you can adapt this system ex-
actly to your automation tasks.
You do not need much wiring because the 24 V DC power supply is integrated
in the backplane bus. Defective electronic modules can be replaced without
having to replace the wiring.
The use of power modules with different colors allows you to define further po-
tential ranges for the 24 V DC power supply within the system or expand the
electronic supply by 2 A.
Fig. 3-1: Cube20S system
Components The Cube20S system consists of the following components:
Bus node
Expansion modules
Accessories
NOTE
The use of the Cube20S system is only permitted with a combination of mod-
ules from Murrelektronik. Operation together with modules of other manufac-
turers is impermissible!

System description
User manual 57120_hdb_en_12 14 / 70
Bus node Bus interface and power module of the bus node are integrated in one hous-
ing. The bus interface is used for connection to a superior bus system.
Both bus interface and the electronics of the connected expansion modules
are supplied with power via the power module.
There is another connection on the power module for the 24 V DC power sup-
ply of the connected expansion modules.
Bus cover
By installing up to 64 expansion modules
on the bus node, they will be electrically
connected, i.e.:
they are incorporated in the back-
plane bus,
the electronic modules are supplied
with power,
each expansion module is connected
to the 24 V DC power supply.
Each bus node has a cover to protect the
contacts.
Remove the cover on the bus node
before installing Cube20 modules.
To protect the contacts, mount the
bus cover on the outermost module.
The bus cover is also available as acces-
sory (see chapter 11.1 "Accessories").

System description
User manual 57120_hdb_en_12 15 / 70
Expansion modules Each expansion module consists of a terminal and an electronic module.
1 Terminal module
2 Electronic module
Terminal module
Electronic module
The terminal module consists of the fol-
lowing functional elements:
sliding mechanism to fasten the elec-
tronic module,
backplane bus with power supply for
the electronics,
connection to the 24 V DC power
supply,
staircase-shaped terminal block for
wiring,
safe locking system for fastening on
a mounting rail.
This locking mechanism allows you to
mount your Cube20S system outside the
control cabinet and fix the complete sys-
tem later in the control cabinet.
The functionality of an expansion module
is defined over the electronic module.
If the electroni c module is defective, it
can be replaced while wiring is kept.
There are LEDs indicating the status
on the front side.
To facilitate wiring, there are wiring di-
agrams on the front and on the side
of each electronic module.

System description
User manual 57120_hdb_en_12 16 / 70
Power modules
Power modules provide the Cube20S
system with power. The power modules
are either integrated into the bus node or
may be plugged in between the expan-
sion modules.
Depending on the type of power module,
groups of potential can be defined for the
24 V DC power supply, or the electronics
supply may be extended by 2 A.
For better recognition, the power modules
have a color different from the expansion
modules.

3.1 Hardware revision
Front printing The hardware revision is printed on each Cube20S module.
Since a Cube20S module consists of a terminal and an electronic module,
the respective hardware revision is printed on both modules.
Important for the hardware revision of a Cube20S module is the hardware
revision of the electronic module, which can be found below the labeling
strip of the respective electronic module.
On modules without labeling strip, the hardware revision is printed on the
front side.
The example below shows the hardware revision 1. The number 1 is identified
with an "X".
Fig. 3-2: Front printing
Web server The hardware version "HW revision" for bus nodes with web server can be
output via the integrated web server.
