5 Safety regulations and installation
notes
5.1 Installation notes
• The category3 device is designed for installation in
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.
WARNING: Risk of electric shock
During operation, certain parts of this device
may carry hazardous voltages. Disregarding
this warning may result in damage to
equipment and/or serious personal injury.
– For applications with high operating
voltages, ensure sufficient distance or
insulation and provide shock protection.
– 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.

the requirements of EN 60079-14.
• In zone2, only connect devices to the supply and signal
circuits that are suitable for operation in the Ex zone 2
and the conditions at the installation location.
• In potentially explosive areas, terminals may only be
snapped onto or off the DIN rail connector and wires
may only be connected or disconnected when the
power is switched off.
• 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 Ex area if it is damaged, was subject to an
impermissible load, stored incorrectly or if it
malfunctions.

6.3 I/O MAP address in the SATEL-LP wireless
system
Figure 3 Thumb wheel
Use the thumbwheel to set the I/O-MAP address. The
extension module in the SATEL-LP 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 SATEL-LP-DOR4 module can be assigned to the
SATEL-LP-DI4 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
Section7).

the I/O extension modules via the bus foot.
Figure 5 SATEL-LP connection station with up to
32I/O extension modules
Assembly
Figure 6 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.
