3.6 Protective Clothing and Equipment
3.7 Reconstruction and Modifications of the Product
3.8 Safety Appliance
3.9 Special Safety Messages
If working with or on the I/O Modules, wear special ESD clothing. Because
static electrification can destroy parts of the buscoupler which can cause a
malfunction of the whole product.
Follow the instructions and regulations of the employer.
Reconstructions and modifications of the product can cause property
damages or personal injuries. Do not reconstruct or modify the product if the
manufacturer does not allow it explicit in writing.
Do not bypass protection equipment and safety arrangements. The product
can be damaged by overvoltage and electric shocks are possible.
The I/O modules do not garuantee the safety of the whole process and/or
the whole system.
Use a nominal operating voltage of 24 Volts. The lower (16.8 Volts) and upper
(30 Volts) threshold voltage is given in the technical data. A higher voltage can
cause electric shocks and damage the product.
Dismount all electronic modules and their connections of the frame if
intended to do some welding. The product can be damaged by compensating
current.

4.2 System Overview
The I/O modules can be integrated in the product line of the DIOLINE20
automating system as follows.
The DIOLINE product line contains modular components. A unit consists of a
controller with an integrated CPU and an extension module. It is possible to
connect max. 10 local I/O extension modules on the controller. The extension
modules are connected over the L-Bus. The graphic shows the DIOLINE product
after their intelligence. The first module is the most intelligent one. The last one is
a module with the fewest intelligence.

To connect the modules correctly read the chapter of the required module. In the
chapters you will also find information about the pin assignments.
9.1 Power Supply
The built in microcontroller of the digital I/O module is feeded by the L-Bus
interface. The power supply has to be connected over the cage clamps of the
modules. Read the required chapter. To ground the module connect the mounting
tab X0.
