Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent damage to property. The
notices referring to your personal safety are highlighted in the manual by a safety alert symbol, notices referring only to property damage
have no safety alert symbol. These notices shown below are graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will be used. A notice warning of
injury to persons with a safety alert symbol may also include a warning relating to property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by
personnel qualified
for the specific task in accordance with
the relevant documentation, in particular its warning notices and safety instructions. Qualified personnel are those who, based on their
training and experience, are capable of identifying risks and avoiding potential hazards when working with these products/systems.
Proper use of Siemens products
Note the following:
WARNING
Siemens products may only be used for the applications described in the catalog and in the relevant technical documentation. If products
and components from other manufacturers are used, these must be recommended or approved by Siemens. Proper transport, storage,
installation, assembly, commissioning, operation and maintenance are required to ensure that the products operate safely and without any
problems. The permissible ambient conditions must be complied with. The information in the relevant documentation must be observed.

Characteristics
Using the power splitter, two antennas can be connected to one antenna connector of a reader. The power fed in at the input
(S) is split over two outputs (1, 2).

Example of a configuration
The following example of a configuration shows a setup with one RF680R reader, one power splitter and two RF640A
antennas.
Figure 3-1 Example of a configuration with an RF600 system with a power splitter
The link between the reader and the power splitter (3.2 dB attenuation) is via a cable 1 m in length (0.5 dB cable
attenuation). Between the power splitter and the antennas a cable with a length of 3 m (1 dB cable attenuation) and a cable
with a length of 5 m (1.25 dB cable attenuation) are used.
To calculate the total attenuation made up of the cable attenuation and the attenuation of the power splitter, the branch with
the lowest cable attenuation must be considered. For the configuration shown above, the total attenuation is as follows:
0.5 dB + 3.2 dB + 1 dB = 4.7 dB
The total attenuation of 4.7 dB must be stored in the configuration of the reader as user-defined cable attenuation. When
using several different antennas, the antenna gain of the antenna with the highest gain must be specified. This ensures that
the maximum permitted transmit power is not exceeded.
Note that when using different antenna cable lengths, the radiated power of the antenna with the longer cable is lower.
