5 Safety regulations and installation notes
5.1 Installation notes for ATEX/IECEx conformance
•The category3 device is designed for installation in
zone2 potentially explosive areas. It meets the
requirements of EN60079-0:2012+A11:2013 and
EN60079-15:2010.
•Installation, operation, and maintenance may only be
carried out by qualified electricians. Follow the
installation instructions as described.
•When installing and operating the device, the
applicable regulations and safety directives (including
national safety directives), as well as general technical
regulations, must be observed. The technical data is
provided in the package slip and on the certificates
(conformity assessment, additional approvals where
applicable).
•The device must not be opened or modified. Do not
repair the device yourself, replace it with an equivalent
device. Repairs may only be carried out by the
manufacturer. The manufacturer is not liable for
damage resulting from violation.
•The IP20 protection (IEC 60529/EN 60529) of the
device is intended for use in a clean and dry
environment. The device must not be subject to
mechanical strain and/or thermal loads, which exceed
the limits described.
•To protect the device against mechanical or electrical
damage, install it in a suitable housing with appropriate
degree of protection as per IEC60529.
•The device is not designed for use in atmospheres with
a danger of dust explosions.
•If dust is present, it is necessary to install into a suitable
approved housing, whereby the surface temperature of
the housing must be taken into consideration.
Installation in zone2
•Install the device in a suitable approved housing (with at
least IP54 protection) that meets the requirements of
EN60079-15.
•Observe the requirements of EN 60079-14.
•Only connect devices to the supply and signal circuits in
zone 2 that are suitable for operation in potentially
explosive areas of zone 2 and for the conditions at the
installation location.
•The switches of the device that can be accessed may
only be actuated when the power supply to the device is
disconnected.
•The device must be stopped and immediately removed
from the hazardous area if it is damaged, was subject to
an impermissible load, stored incorrectly or if it
malfunctions.
WARNING: Risk of electric shock
– Provide a switch/circuit breaker close to
the device, which is labeled as the
disconnect device for this device or the
entire control cabinet.
– Disconnect the device from all power
sources during maintenance work and
configuration (the device can remain
connected to SELV or PELV circuits).
– The housing of the device provides a
basic insulation against the neighboring
devices, for 300 V eff. If several devices
are installed next to each other, this has
to be taken into account, and additional
insulation has to be installed if necessary.
If the neighboring device is equipped with
basic insulation, no additional insulation
is necessary.
WARNING:
Observe the following safety notes when
using the device.
WARNING: Explosion hazard when used
in potentially explosive areas
Please make sure that the following notes and
instructions are observed.

6.3 Configuration
The DIP switches on the front configure the input signal
ranges (0 to 5V or 0 to 10V).
Figure 4 DIP switches
I/O MAP address
Figure 5 Thumbwheel
Use the thumbwheel to set the I/O MAP address. The
extension module in the Radioline wireless system is
addressed using the I/O MAP address.
On the entire wireless network, addresses 1 to 99 (I/O MAP)
(maximum) may be assigned for the I/O extension modules.
Wireless module in I/O data mode
The input device must be provided with the same I/O MAP
address as the assigned output device at the other wireless
station (I/O mapping).
The I/O MAP address of an input module may only appear
once in the network.
Only the RAD-AO4-IFS module can be assigned to the
RAD-AI4-U-IFS module.
Wireless module in PLC/Modbus RTU mode
The I/O MAP address of an input module may only appear
once in the network.
The input data is saved in a Modbus memory map in the
master wireless module.
You can read or write the process data via the serial
interface of the master wireless module (RAD-ID=01) using
the Modbus RTU commands (see Section7).

6.4 Display and diagnostic elements
The I/O extension module uses a total of three LEDs to
indicate the operating states.
Figure 6 Display and diagnostic elements
6.5 Analog input
The analog input of the extension module is able to process
0 to 5V and 0 to 10V signals.
All the inputs are electrically isolated from one another, from
the supply voltage (via bus foot), and from other electronic
components.
A supply voltage of 12VDC, 30 mA maximum, is available
at the connection terminal block (PWR1) for the use of
passive sensors (1 in Figure 2, connection assignment see
Figure 3).
6.6 Mounting and removing
Connection station with I/O extension modules
Up to 32different I/O extension modules can be connected
to every wireless module via the DIN rail connector (see
accessories). Data is transmitted and power is supplied to
the I/O extension modules via the bus foot.

connector in connection with 24 V DC devices.
1. Connect the DIN rail connectors together for a
connection station.
2. Push the connected DIN rail connectors into the DIN
rail.
3. Hold the device above the DIN rail, ensuring that the
device and DINrail connector are aligned correctly, and
rotate the device into the DIN rail and connector until it
snaps fast.
4. Connect the desired number of I/O extension modules
to the wireless module via the DIN rail connector.
•In order to meet the requirements for the protection
class, install the device in suitable housing.
•During startup, check that the device is operating,
wired, and marked correctly.
•You can establish a connection between two DIN rail
connectors using MINI COMBICON connectors:
MC 1,5/5-ST-3,81 (female, 1803604); IMC 1,5/5-ST-
3,81 (male, 1857919).
Removing
1. Use a suitable screwdriver to release the locking
mechanism on the snap-on foot of the device.
2. Rotate the device away from the DIN rail.
3. Carefully lift the device off the DIN rail and DIN rail
connector.
6.7 Connecting cables
Figure 9 Connecting cables
•Crimp ferrules to the wires.
Permissible cable cross section: 0.2...2.5mm².
•Insert the wire with ferrule into the corresponding
