ATTENTION
Radiated electromagnetic field strengths
w
The device sends ultrahigh frequency electromagnetic waves. It complies with the
country-specific limit values for the public and workers.
u
Disconnect the device in the vicinity of medical equipment.
6.1 Installation instructions for devices
Devices installed next to each other interfere if they are not configured correspondingly.
When mounting several RFID units adhere to the minimum distances between the systems.
Installing a unit in or on metal reduces the read and write distance.
Device performance can be affected if positioned in the immediate vicinity of powerful HF
emission sources such as welding transformers or converters.
6.2 Installation instructions for ID tags
For installation in and on metal use the ID tags provided for this purpose.
Position the ID tag in the area of the sensing face. When doing so, the angle of aperture and the
operating distance must be adhered to (→ Data sheet of the device).
Align the axes of the RFID device and the ID-TAG in the same way.
6.3 Avoiding interference
The device generates a modulated electromagnetic field with a frequency of 13.56 MHz.
Interference in data communication is avoided if there are no other RFID UHF devices in the vicinity. If
there are other RFID UHF devices in the vicinity:
u
The mounting distances between the devices should be as large as possible.
u
Use the RSSI filter.
u
Use the devices in alternating operation.
u
Switch the HF field of the device on/off.
The UHF field is attenuated if there are people or objects (cables, metal profiles, etc.) between
the device and ID tag.
u
Keep the area between the device and ID tag clear during reading or writing.
