zone2 potentially explosive areas. It meets the
requirements of EN60079-0:2012+A11:2013 and
EN60079-15:2010.
• 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 IEC60529.
• 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.
5.2 Installation in Zone 2
• Observe the specified conditions for use in potentially

5.3 UL Notes
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.

6.3 Setting the DIP switches
The DIP switches on the front can be used to set the
behavior of the outputs in the event of an error
(e.g.,interruption of the bus communication by interruption
of the wireless connection).
For digital outputs DO1...DO4 and DO5...DO8 you can
choose between:
– Reset
– Hold last valid state (Hold)
Figure 3 DIP switches
6.4 Network applications (operating mode)
You can set the network application of the wireless module
with the SATEL-LP-CONF software. All SATEL-LP wireless
modules are set to I/O data mode (wire in/wire out) by
default.
Wireless module in I/O data mode
In an I/O-to-I/O network, only the I/O signals of the
connected analog and digital I/O extension modules are
transmitted. Assign the inputs and outputs of the extension
modules quickly using the white thumbwheel.
In this mode, the serial RS-232 and RS-485 interfaces on
the wireless module are deactivated.
Wireless module in PLC/Modbus RTU mode
In PLC/Modbus RTU mode, the wireless master operates as
a Modbus slave. The master PLC controls all commands
and initiates all data requests.
Input and output data is stored in a Modbus Memory Map in
the master wireless module. In this mode, you can access
process and diagnostic data for the individual network
devices via a Modbus controller.

Wireless module in I/O data mode
The output device must be provided with the same I/O MAP
address as the assigned input device at the other wireless
station (I/O mapping).
Output modules with the same I/O MAP address may
appear several times in the network at different stations.
Only the SATEL-LP-DI8 module can be assigned to the
SATEL-LP-DO8 module.
Wireless module in PLC/Modbus RTU mode
The I/O MAP address may only appear once in the network.
Exception: Output modules with the same I/O MAP address
may appear several times in the network at different
stations.
The output 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
Section7).
6.6 Display and diagnostic elements
The I/O extension module uses a total of eleven LEDs to
indicate the operating states.
Figure 5 Display and diagnostic elements
6.7 Digital outputs
The eight outputs are arranged in two groups of four outputs
each with a common electrical supply. The two output
groups are electrically isolated from one another, from the
supply voltage (via bus foot), and from other electronic
components.
The digital outputs must be externally supplied.
Outputs DO1...DO4 are supplied using terminals 1.1 and
1.2/1.3.
Outputs DO5...DO8 are supplied using terminals 6.1 and
6.2/6.3.

6.8 Mounting and removing
Connection station with I/O extension modules
Up to 32different 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.
Figure 6 SATEL-LP connection station with up to
32I/O extension modules
Assembly
Figure 7 Mounting and removing
When using the device in a connection station, use the
17.5 mm wide DIN rail connector supplied. Only use the DIN
rail connector in connection with 24 V DC devices.
• Connect the DIN rail connectors together for a
connection station.
• Push the connected DIN rail connectors into the DIN
rail.
• Place the device onto the DIN rail from above. Ensure
the device and DIN rail connector are aligned correctly.
• Holding the device by the housing cover, carefully push
the device towards the mounting surface so that the
device bus connector is securely fixed onto the DIN rail
connector.
• Once the snap-on foot has been audibly snapped onto
the DIN rail, check that it is fixed securely. The device is
only mechanically secured via the DIN rail.
• 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.
Removing
• Use a suitable screwdriver to release the locking
mechanism on the snap-on foot of the device.
• Hold onto the device by the housing cover and carefully
tilt it upwards.
• Carefully lift the device off the DIN rail connector and the
DIN rail.
Only mount the I/O extension modules to the
right of the wireless module.
